Description

本発明は、光通信分野やマイクロ波通信およびミリ波通信等の分野で用いられる、高い周波数帯で作動する各種電子部品を収納する電子部品搭載用パッケージおよびこれを用いた電子装置に関する。   The present invention relates to an electronic component mounting package for storing various electronic components operating in a high frequency band, and an electronic apparatus using the same, which are used in the fields of optical communication, microwave communication, millimeter wave communication, and the like.

近年、40ｋｍ以下の伝送距離における高速通信に対する需要が急激に増加しており、高速大容量の情報伝送に関する研究開発が進められている。とりわけ、光通信装置を用いて光信号を受発信する半導体装置等の電子装置の高速化が注目されており、電子装置による光信号の高出力化と高速化が伝送容量を向上させるための課題として研究開発されている。   In recent years, the demand for high-speed communication at a transmission distance of 40 km or less has increased rapidly, and research and development on high-speed and large-capacity information transmission has been promoted. In particular, increasing speed of electronic devices such as semiconductor devices that receive and transmit optical signals using optical communication devices has been attracting attention, and the issue of increasing the output and speed of optical signals by electronic devices to improve transmission capacity As research and development.

従来の半導体装置に代表される電子装置の光出力は0.2〜0.5ｍＷ程度であり、電子部品として用いられる半導体素子の駆動電力は５ｍＷ程度であった。しかし、より大出力の半導体装置では、光出力が１ｍＷのレベルになってきており、また、半導体素子の駆動電力も10ｍＷ以上が要求されている。さらに、従来の半導体装置による伝送信号の周波数は2.5〜10ＧＨｚ程度であったが、近年では要求される伝送速度が高まり、伝送信号の周波数が25〜40ＧＨｚ程度まで向上してきており、半導体装置をより高出力化させ、高速化させることが要求されている。   The optical output of an electronic device typified by a conventional semiconductor device is about 0.2 to 0.5 mW, and the driving power of a semiconductor element used as an electronic component is about 5 mW. However, in a semiconductor device having a higher output, the optical output has become a level of 1 mW, and the driving power of the semiconductor element is required to be 10 mW or more. Furthermore, the frequency of the transmission signal by the conventional semiconductor device was about 2.5 to 10 GHz. However, in recent years, the required transmission speed has been increased, and the frequency of the transmission signal has been improved to about 25 to 40 GHz. There is a demand for higher output and higher speed.

光通信装置に用いられているＬＤ（Laser Diode：レーザダイオード）やＰＤ（Photo Diode：フォトダイオ−ド）等の光半導体素子を含む電子部品を従来の電子部品搭載用パッケージに搭載した電子装置の斜視図を図13に、また図13のＡ−Ａ線における断面図を図14に示す。従来の電子部品搭載用パッケージは、円板状の金属製の基体104に、基体104の上面から下面にかけて貫通する貫通孔104ｃを設け、この貫通孔104ｃに充填された絶縁性ガラスから成る封止材105を貫通して信号端子102が固定されているものである。また、基体104の下面には、２つの貫通孔104ｃ・104ｃの間に接地端子106が接続されている。この電子部品搭載用パッケージの上面に電子部品107を搭載し、電子部品搭載用パッケージの信号端子102の上端部と電子部品108の端子とをボンディングワイヤ108を介して電気的に接続し、基体104の上面の外周領域に電子部品107を覆うように金属製の蓋体109を溶接またはろう接により接合部104ｂに接合して気密封止することにより、電子装置としていた。また、蓋体109の電子部品107と対向する部分に光ファイバを固定したり、電子部品107と対向する部分に光を透過させる窓を設けたりしたものもある（例えば、特許文献１，特許文献２を参照。）。   An electronic device in which an electronic component including an optical semiconductor element such as an LD (Laser Diode) or PD (Photo Diode) used in an optical communication device is mounted on a conventional electronic component mounting package. FIG. 13 is a perspective view, and FIG. 14 is a cross-sectional view taken along line AA in FIG. In a conventional electronic component mounting package, a disk-shaped metal base 104 is provided with a through-hole 104c penetrating from the upper surface to the lower surface of the base 104, and sealing is made of insulating glass filled in the through-hole 104c. The signal terminal 102 is fixed through the material 105. In addition, a ground terminal 106 is connected to the lower surface of the base body 104 between the two through holes 104c and 104c. The electronic component 107 is mounted on the upper surface of the electronic component mounting package, the upper end portion of the signal terminal 102 of the electronic component mounting package and the terminal of the electronic component 108 are electrically connected via the bonding wire 108, and the base 104 A metal lid 109 is joined to the joint 104b by welding or brazing so as to cover the electronic component 107 in the outer peripheral area of the upper surface of the above, and hermetically sealed. In addition, there is a case in which an optical fiber is fixed to a portion of the lid 109 facing the electronic component 107 or a window for transmitting light is provided in a portion facing the electronic component 107 (for example, Patent Document 1, Patent Document). 2).

このような電子装置では、信号端子102と電子部品107の端子とはボンディングワイヤ108を介して電気的に接続されており、ボンディングワイヤ108と接地面である搭載面104ａとの間の浮遊容量が大きいので、高周波信号の伝送損失が大きいものであった。このため、図15に斜視図で、図16に図15のＡ−Ａ線における断面図で示すように、基体104から突出した搭載部104ａを設け、基体104に対して略垂直な搭載部104ａの搭載面104ｂに搭載した配線基板101に電子部品107を搭載して、配線基板101の基板101a上に形成された信号線路導体101ｂと信号端子102とをろう材103で接合することにより電気的接続を行ない、より伝送特性を向上させることも行なわれていた。   In such an electronic device, the signal terminal 102 and the terminal of the electronic component 107 are electrically connected via the bonding wire 108, and the stray capacitance between the bonding wire 108 and the mounting surface 104a that is the ground plane is generated. Since it is large, the transmission loss of the high frequency signal is large. Therefore, as shown in the perspective view of FIG. 15 and the cross-sectional view taken along the line AA of FIG. 15, the mounting portion 104a protruding from the base body 104 is provided, and the mounting portion 104a substantially perpendicular to the base body 104 is provided. The electronic component 107 is mounted on the wiring board 101 mounted on the mounting surface 104b of the wiring board 101, and the signal line conductor 101b and the signal terminal 102 formed on the board 101a of the wiring board 101 are joined by the brazing material 103 to electrically Connections have been made to further improve transmission characteristics.

また、同様に高周波信号を伝送するための電子部品搭載用パッケージとして、基体の上面の搭載部に半導体素子および配線基板を搭載し、この載置部を囲むように、側部に貫通孔が形成された枠体を取り付け、貫通孔内に充填された封止材を貫通して固定された信号端子と配線基板上の信号線路導体とをろう材で接合することにより電気的に接続したものがある。そして、このような構造の電子部品搭載用パッケージにおいて、信号端子の信号線路導体との接続部分の厚さを残部の10〜50％とすることで、インピーダンスギャップを小さくすることが提案されている（例えば、特許文献３を参照。）。
特開2006−179775号公報 特開平８−130266号公報 特開2002−319643号公報 Similarly, as an electronic component mounting package for transmitting a high-frequency signal, a semiconductor element and a wiring board are mounted on the mounting portion on the upper surface of the base, and a through hole is formed in the side portion so as to surround the mounting portion. The frame body is attached and electrically connected by joining the signal terminal fixed through the sealing material filled in the through hole and the signal line conductor on the wiring board with a brazing material. is there. In the electronic component mounting package having such a structure, it has been proposed to reduce the impedance gap by setting the thickness of the connection portion of the signal terminal to the signal line conductor to 10 to 50% of the remaining portion. (For example, see Patent Document 3).

しかしながら、近年、伝送される情報量の増大に伴い伝送信号の高周波化および伝送速度の高速化がさらに進んでおり、30ＧＨｚ以上のより高い周波数の信号を伝送する場合においては、信号端子の厚みを薄くしインピーダンスギャップを小さくしても、無視できるほど十分に小さなものではなくなってきているという問題があった。これは、従来の電子部品搭載用パッケージにおける信号端子と信号線路導体との接続構造は、信号端子と信号線路導体とを上下に重ねてその間のろう材により接続しているものであることから、この信号端子と信号線路導体とが上下に重なった接続部分では、信号端子の厚みを薄くしても残りの信号端子の厚みとろう材の厚みとにより信号線路導体の厚みが見かけ上厚くなってしまうことによるものであった。すなわち、信号線路導体の厚みが厚くなることによりこの接続部分の側面の面積が増加し、この面積が増加した側面と配線基板の下面の接地導体（接地電極に接続された搭載部）との間の結合が増加することにより、この接続部分のインピーダンスが小さくなってしまい、信号線路導体の信号端子と重なっていない部分とでインピーダンスギャップが発生し、より高い周波数の信号を伝送する場合は、小さなインピーダンスギャップでも反射損失が大きくなり、伝送効率が低下してしまうからである。   However, in recent years, with the increase in the amount of information to be transmitted, the frequency of transmission signals and the transmission speed have been further increased, and in the case of transmitting a signal with a higher frequency of 30 GHz or higher, the thickness of the signal terminal is reduced. There is a problem that even if the impedance gap is reduced by making it thinner, it is no longer small enough to be ignored. This is because the connection structure between the signal terminal and the signal line conductor in the conventional electronic component mounting package is such that the signal terminal and the signal line conductor are overlapped with each other by a brazing material therebetween, In the connection part where the signal terminal and the signal line conductor overlap each other, the thickness of the signal line conductor is apparently thick due to the remaining thickness of the signal terminal and the thickness of the brazing material even if the signal terminal is thin. It was due to that. That is, as the thickness of the signal line conductor increases, the area of the side surface of the connection portion increases, and the area between the increased side surface and the ground conductor on the lower surface of the wiring board (the mounting portion connected to the ground electrode) When the coupling of the signal line conductor increases, the impedance of this connection part becomes small, an impedance gap is generated in the part that does not overlap the signal terminal of the signal line conductor, and if a higher frequency signal is transmitted, it is small. This is because reflection loss increases even in the impedance gap, and transmission efficiency decreases.

本発明は上記問題点に鑑み完成されたものであり、その目的は、より高周波化が進んでも、高周波信号の入出力時における反射損失を小さくすることにより、電子部品の高周波での作動性が良好な信号端子と信号線路導体との接続構造を提供することにある。また、本発明の他の目的は、その信号端子と信号線路導体との接続構造を用いた高周波での作動が良好な電子部品搭載用パッケージを提供することにある。また、本発明のさらに他の目的は、その電子部品搭載用パッケージを用いた、高周波での作動が良好な電子装置を提供することにある。   The present invention has been completed in view of the above problems, and its purpose is to improve the operability of electronic components at high frequencies by reducing reflection loss at the time of input / output of high frequency signals even if the frequency is increased. An object is to provide a connection structure between a good signal terminal and a signal line conductor. Another object of the present invention is to provide an electronic component mounting package that uses a connection structure between the signal terminal and the signal line conductor and that operates well at high frequencies. It is still another object of the present invention to provide an electronic device that uses the electronic component mounting package and has favorable operation at high frequencies.

本発明の信号端子と信号線路導体との接続構造は、高周波信号を伝送する線状の導体からなる信号端子が、配線基板の一方の主面の端部に形成された、底面が前記主面より低い段差部の前記底面に接するとともに、前記配線基板の前記主面に前記段差部まで形成された信号線路導体に、前記主面側から見て前記信号端子と前記信号線路導体とが上下に重ならずに同一線上に連続して配置され、前記配線基板の側面側から見て前記信号端子と前記配線基板とが重なるように配置されてろう材により接続されていることを特徴とするものである。   In the connection structure between the signal terminal and the signal line conductor of the present invention, the signal terminal made of a linear conductor for transmitting a high-frequency signal is formed at the end of one main surface of the wiring board, and the bottom surface is the main surface. A signal line conductor formed on the main surface of the wiring board up to the step portion is in contact with the bottom surface of the lower step portion, and the signal terminal and the signal line conductor are vertically arranged when viewed from the main surface side. It is arranged continuously on the same line without overlapping, and the signal terminal and the wiring board are arranged so as to overlap each other when viewed from the side surface side of the wiring board and are connected by a brazing material It is.

また、本発明の信号端子と信号線路導体との接続構造は、上記構成において、前記信号端子は、前記段差部の前記底面に接着されていることを特徴とするものである。   Further, the connection structure between the signal terminal and the signal line conductor according to the present invention is characterized in that, in the above configuration, the signal terminal is bonded to the bottom surface of the step portion.

また、本発明の信号端子と信号線路導体との接続構造は、上記構成において、前記配線基板の側面側から見て前記信号端子の中心と前記信号線路導体の上面とが重なるように配置されていることを特徴とするものである。   Further, the connection structure between the signal terminal and the signal line conductor of the present invention is arranged so that the center of the signal terminal and the upper surface of the signal line conductor are overlapped when viewed from the side surface side of the wiring board in the above configuration. It is characterized by being.

また、本発明の信号端子と信号線路導体との接続構造は、上記構成において、前記信号端子の端面が対向する段差部の側面に側面導体が形成されており、該側面導体に前記信号端子の前記端面がろう材により接続されていることを特徴とするものである。   Further, in the connection structure between the signal terminal and the signal line conductor of the present invention, in the above configuration, a side conductor is formed on the side surface of the stepped portion where the end face of the signal terminal faces, and the side of the signal terminal is connected to the side conductor. The end faces are connected by a brazing material.

本発明の電子部品搭載用パッケージは、上記いずれかの本発明の信号端子と信号線路導体との接続構造を有することを特徴とするものである。   The electronic component mounting package of the present invention is characterized by having a connection structure between any of the signal terminals of the present invention and a signal line conductor.

本発明の電子装置は、上記本発明の電子部品搭載用パッケージに電子部品が実装されて前記信号線路導体に接続されていることを特徴とするものである。   The electronic device of the present invention is characterized in that an electronic component is mounted on the electronic component mounting package of the present invention and connected to the signal line conductor.

本発明の信号端子と信号線路導体との接続構造によれば、高周波信号を伝送する線状の導体からなる信号端子が、配線基板の一方の主面の端部に形成された、底面が前記主面より低い段差部の前記底面に接するとともに、配線基板の主面に段差部まで形成された信号線路導体に、主面側から見て信号端子と信号線路導体とが上下に重ならずに同一線上に連続して配置され、配線基板の側面側から見て信号端子と配線基板とが重なるように配置されてろう材により接続されていることから、段差部の高さの設定により信号端子と信号線路導体との接続部において信号線路導体の見かけ上の厚みが厚くなることを容易に抑えることができるので、接続部での特性インピーダンスの不整合が小さくなり、高周波信号の反射損失が小さく伝送特性が良好な接続構造となる。   According to the connection structure of the signal terminal and the signal line conductor of the present invention, the signal terminal made of a linear conductor for transmitting a high-frequency signal is formed at the end of one main surface of the wiring board, and the bottom surface is the above-mentioned The signal line conductor formed on the main surface of the wiring board up to the stepped portion does not overlap the signal terminal and the signal line conductor when viewed from the main surface side while contacting the bottom surface of the stepped portion lower than the main surface. Since the signal terminal and the wiring board are arranged so as to overlap each other when viewed from the side of the wiring board and are connected by the brazing material, the signal terminal is set by setting the height of the stepped portion. It is possible to easily suppress an increase in the apparent thickness of the signal line conductor at the connection part between the signal line conductor and the signal line conductor, thereby reducing the characteristic impedance mismatch at the connection part and reducing the reflection loss of the high-frequency signal. Good transmission characteristics The Do connection structure.

また、本発明の信号端子と信号線路導体との接続構造によれば、上記構成において、信号端子は、段差部の底面に接着されていることから、信号端子が信号線路導体が形成された配線基板に対して段差部でも固定されるので、信号端子と信号線路導体とをろう材だけで接合する場合と比較して、信号端子と信号線路導体との間のろう材に加わる応力を低減することができ、信号端子と信号線路導体との接続信頼性を高めることができる。   Further, according to the connection structure between the signal terminal and the signal line conductor of the present invention, in the above configuration, the signal terminal is bonded to the bottom surface of the stepped portion, so that the signal terminal is a wiring in which the signal line conductor is formed. Since the step is also fixed to the substrate, the stress applied to the brazing material between the signal terminal and the signal line conductor is reduced compared to the case where the signal terminal and the signal line conductor are joined only by the brazing material. The connection reliability between the signal terminal and the signal line conductor can be improved.

また、本発明の信号端子と信号線路導体との接続構造によれば、上記構成において、配線基板の側面側から見て信号端子の中心と前記信号線路導体の上面とが重なるように配置されている場合は、信号端子の上下の表面それぞれから信号線路導体の上面への距離の差が最も小さくなり、信号端子の上下それぞれの表面を伝送して信号線路導体に入射する高周波信号におけるそれぞれの伝送経路の長さの差が最も小さくなるので、反射損失がより小さくなり、高周波信号の伝送特性がより良好なものとなる。   Further, according to the connection structure between the signal terminal and the signal line conductor of the present invention, in the above configuration, the center of the signal terminal and the upper surface of the signal line conductor are arranged so as to overlap each other when viewed from the side surface side of the wiring board. The difference in distance from the upper and lower surfaces of the signal terminal to the upper surface of the signal line conductor is the smallest, and the respective transmissions in the high-frequency signal transmitted through the upper and lower surfaces of the signal terminal and incident on the signal line conductor Since the path length difference is the smallest, the reflection loss is smaller and the transmission characteristics of the high-frequency signal are better.

また、本発明の信号端子と信号線路導体との接続構造によれば、上記構成において、信号端子の端面が対向する段差部の側面に側面導体が形成されており、この側面導体に信号端子の端面がろう材により接続されている場合は、側面導体により、ろう材による信号端子と配線基板との接合面積が増加して信号端子と信号線路導体の接合が補強されるので、接合信頼性がより優れた接続構造となる。   Further, according to the connection structure of the signal terminal and the signal line conductor of the present invention, in the above configuration, the side conductor is formed on the side surface of the stepped portion where the end face of the signal terminal faces, and the signal conductor is connected to the side conductor. When the end faces are connected by a brazing material, the side conductor increases the bonding area between the signal terminal and the wiring board by the brazing material and reinforces the bonding between the signal terminal and the signal line conductor. A better connection structure.

本発明の電子部品搭載用パッケージによれば、上記いずれかの本発明の信号端子と信号線路導体との接続構造を有することから、信号端子と信号線路導体との接合部での特性インピーダンスのずれを小さくできるので、高周波信号の反射損失を小さくすることができ、高周波での作動が良好な電子部品搭載用パッケージとなる。   According to the electronic component mounting package of the present invention, since it has the connection structure between the signal terminal and the signal line conductor according to any one of the present inventions described above, the characteristic impedance shift at the junction between the signal terminal and the signal line conductor Therefore, the reflection loss of the high-frequency signal can be reduced, and the electronic component mounting package can be operated with high frequency.

本発明の電子装置によれば、本発明の電子部品搭載用パッケージに電子部品が実装されて信号線路導体に接続されていることにより、信号端子と信号線路導体との接合部での特性インピーダンスのずれを小さくできるので、高周波信号の反射損失を小さくすることができ、高周波での作動が良好な電子装置となる。   According to the electronic device of the present invention, since the electronic component is mounted on the electronic component mounting package of the present invention and connected to the signal line conductor, the characteristic impedance at the joint between the signal terminal and the signal line conductor is reduced. Since the deviation can be reduced, the reflection loss of the high-frequency signal can be reduced, and the electronic device can operate well at high frequencies.

The wiring board 1 is mounted on the side mounting surface 4b, and the side surfaces of the signal terminals 2 and 2 fixed through the sealing material 5 filled in the through holes 4c formed in the base body 4 are the wiring board. 1 is in contact with the bottom surface of the stepped portion 1e, and its end is connected to the signal line conductor 1b on the main surface of the wiring board 1 by a brazing material 3 such as solder. Then, the electronic component 7 is mounted on the grounding conductor 1c of the wiring board 1, and the terminal of the electronic component 7 is connected to the signal line conductor 1b on the wiring board 1 by the bonding wire 8, and as shown in FIG. In addition, the electronic device of the present invention is basically configured by joining the lid 9 as shown by the broken line to the joint 4d on the upper surface of the substrate 4.

本発明の信号端子２と信号線路導体１ｂとの接続構造は、図３に示すように、高周波信号を伝送する線状の導体からなる信号端子２が、配線基板１の一方の主面の端部に形成された、底面が主面より低い段差部１ｅの底面に接するとともに、配線基板１の主面に段差部１ｅまで形成された信号線路導体１ｂに、主面側から見て信号端子２と信号線路導体１ｂとが上下に重ならずに同一線上に連続して配置され、その線に交差する方向の配線基板１の側面側から見て信号端子２と配線基板１とが前後で重なるように配置されて、両者の端部間に配置したろう材３により接続されていることを特徴とするものである。   The connection structure between the signal terminal 2 and the signal line conductor 1b according to the present invention is such that the signal terminal 2 made of a linear conductor for transmitting a high-frequency signal is connected to the end of one main surface of the wiring board 1, as shown in FIG. The signal line conductor 1b formed on the signal line conductor 1b formed on the main surface of the wiring board 1 up to the stepped portion 1e is in contact with the bottom surface of the stepped portion 1e formed on the main surface. And the signal line conductor 1b are arranged continuously on the same line without overlapping vertically, and the signal terminal 2 and the wiring board 1 overlap in the front and rear direction when viewed from the side of the wiring board 1 in the direction intersecting the line. It arrange | positions in this way, It is characterized by being connected by the brazing | wax material 3 arrange | positioned between both edge part.

このことから、信号端子２と信号線路導体１ｂとを上下に重ねてその間のろう材３により接続した従来の接続構造と比較すると、段差部１ｅの高さの設定により信号端子２と信号線路導体１ｂとの接続部において信号線路導体１ｂの見かけ上の厚みが厚くなることを容易に抑えることができるので、接続部での特性インピーダンスの不整合が小さくなり、高周波信号の反射損失が小さく伝送特性が良好な接続構造となる。   Therefore, as compared with the conventional connection structure in which the signal terminal 2 and the signal line conductor 1b are overlapped with each other and connected by the brazing material 3 therebetween, the signal terminal 2 and the signal line conductor are set by setting the height of the step portion 1e. Since it is possible to easily suppress the apparent thickness of the signal line conductor 1b at the connection portion with 1b, mismatching of characteristic impedance at the connection portion is reduced, reflection loss of high-frequency signals is reduced, and transmission characteristics are reduced. Is a good connection structure.

図４は本発明の電子部品搭載用パッケージの実施の形態の一例の信号端子２と信号線路導体１ｂとの接続部を拡大して示す側面図であり、図５は図４におけるＢ部を拡大した一例を示す斜視図であり、図６は図３と同様の本発明の電子部品搭載用パッケージの実施の形態の一例を示す断面図であり、信号端子２と信号線路導体１ｂとの接続部を拡大して示したものである。図４〜図６において、図１〜図３と同様の部位には同じ符号を付しており、10は接着剤である。   4 is an enlarged side view showing a connecting portion between the signal terminal 2 and the signal line conductor 1b as an example of an embodiment of the electronic component mounting package according to the present invention, and FIG. 5 is an enlarged view of a portion B in FIG. 6 is a cross-sectional view showing an example of an embodiment of the electronic component mounting package of the present invention similar to FIG. 3, and is a connection portion between the signal terminal 2 and the signal line conductor 1b. Is an enlarged view. 4-6, the same code | symbol is attached | subjected to the site | part similar to FIGS. 1-3, 10 is an adhesive agent.

本発明の信号端子２と信号線路導体１ｂとの接続構造は、図４〜図６に示す例のように、上記構成において、信号端子２は段差部１ｅの底面に接着されていることを特徴とするものである。   The connection structure between the signal terminal 2 and the signal line conductor 1b according to the present invention is characterized in that, in the above configuration, the signal terminal 2 is bonded to the bottom surface of the step portion 1e as shown in the examples shown in FIGS. It is what.

このことにより、信号端子２は信号線路導体１ｂが形成された配線基板１に対して段差部１ｅでも固定されるので、信号端子２と信号線路導体１ｂとをろう材３だけで接合する場合と比較して、信号端子２と信号線路導体１ｂとの間のろう材に加わる応力を低減することができ、信号端子２と信号線路導体１ｂとの接続信頼性を高めることができる。   As a result, the signal terminal 2 is fixed to the wiring board 1 on which the signal line conductor 1b is formed even at the stepped portion 1e. Therefore, the signal terminal 2 and the signal line conductor 1b are joined only by the brazing material 3; In comparison, the stress applied to the brazing material between the signal terminal 2 and the signal line conductor 1b can be reduced, and the connection reliability between the signal terminal 2 and the signal line conductor 1b can be increased.

また、本発明の信号端子２と信号線路導体１ｂとの接続構造は、図３〜図６に示す例のように、上記構成において、配線基板１の側面側（信号端子２と信号線路導１ｂとが同一線上に配置されているその線に交差する方向の側面の側）から見て、信号端子２の中心と信号線路導体１ｂの上面とが重なるように配置されていることが好ましい。   Further, the connection structure between the signal terminal 2 and the signal line conductor 1b according to the present invention is the same as the example shown in FIGS. 3 to 6, in the above configuration, the side surface side of the wiring board 1 (the signal terminal 2 and the signal line conductor 1b). Are arranged so that the center of the signal terminal 2 and the upper surface of the signal line conductor 1b overlap each other when viewed from the side of the side in the direction intersecting with the line arranged on the same line.

このことにより、信号端子２の上下の表面それぞれからろう材３を介して信号線路導体１ｂの上面への距離の差が最も小さくなり、信号端子２の上下それぞれの表面を伝送してろう材３を介して信号線路導体１ｂに入射する高周波信号におけるそれぞれの伝送経路の長さの差が最も小さくなる。また、信号端子２と信号線路導体１ｂとの間のろう材３による信号の伝送経路も短くなり、信号端子２や信号線路導体１ｂに対して高周波信号の伝送経路の屈曲角度が小さいものとなる。このようなことから、信号端子２と信号線路導体１ｂとの接続部における反射損失がより小さくなり、高周波信号の伝送特性がより良好なものとなる。   As a result, the difference in distance from the upper and lower surfaces of the signal terminal 2 to the upper surface of the signal line conductor 1b via the brazing material 3 is minimized, and the brazing material 3 is transmitted through the upper and lower surfaces of the signal terminal 2 respectively. The difference in the lengths of the respective transmission paths in the high-frequency signal incident on the signal line conductor 1b via the line is the smallest. Also, the signal transmission path by the brazing material 3 between the signal terminal 2 and the signal line conductor 1b is shortened, and the bending angle of the high-frequency signal transmission path is small with respect to the signal terminal 2 and the signal line conductor 1b. . For this reason, the reflection loss at the connection portion between the signal terminal 2 and the signal line conductor 1b becomes smaller, and the transmission characteristics of the high-frequency signal become better.

図７は、図３と同様の本発明の電子部品搭載用パッケージの一例を示す断面図であり、信号端子２と信号線路導体１ｂとの接続部を拡大して示したものである。また、図８は、図７におけるＢ部を拡大した一例を示す斜視図である。図７および図８において、図１〜図３と同様の部位には同じ符号を付しており、１ｆは信号端子２が対向する段差部１ｅの側面に設けられた側面導体である。   FIG. 7 is a cross-sectional view showing an example of an electronic component mounting package of the present invention similar to FIG. 3, and shows an enlarged connection portion between the signal terminal 2 and the signal line conductor 1b. FIG. 8 is a perspective view showing an example in which the portion B in FIG. 7 is enlarged. 7 and 8, the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and 1f is a side conductor provided on the side surface of the stepped portion 1e that the signal terminal 2 faces.

本発明の信号端子２と信号線路導体１ｂとの接続構造は、上記構成において、図７および図８に示すように、信号端子２の端面が対向する段差部１ｅの側面に側面導体１ｆが形成されており、側面導体１ｆに信号端子２の端面がろう材３により接続されているときには、側面導体１ｆにより、ろう材３による信号端子２と配線基板１との接合面積が増加して信号端子２と信号線路導体１ｂの接合が補強されるので、接合信頼性がより優れた接続構造となる。   In the connection structure between the signal terminal 2 and the signal line conductor 1b of the present invention, as shown in FIGS. 7 and 8, the side conductor 1f is formed on the side surface of the stepped portion 1e where the end face of the signal terminal 2 faces. When the end face of the signal terminal 2 is connected to the side conductor 1f by the brazing material 3, the joining area between the signal terminal 2 and the wiring board 1 by the brazing material 3 is increased by the side conductor 1f. 2 and the signal line conductor 1b are reinforced, resulting in a connection structure with better joint reliability.

本発明の電子部品搭載用パッケージは、上記いずれかの本発明の信号端子２と信号線路導体１ｂとの接続構造を有することを特徴とするものである。このことから、信号端子２と信号線路導体１ｂとの接合部での特性インピーダンスのずれを小さくできるので、高周波信号の反射損失を小さくすることができ、高周波での作動が良好な電子部品搭載用パッケージとなる。   The electronic component mounting package of the present invention is characterized by having a connection structure between any one of the signal terminals 2 of the present invention and the signal line conductor 1b. As a result, the deviation of the characteristic impedance at the junction between the signal terminal 2 and the signal line conductor 1b can be reduced, so that the reflection loss of the high-frequency signal can be reduced and the operation at high frequency is good. It becomes a package.

本発明の電子装置は、上記本発明の電子部品搭載用パッケージに電子部品７が実装されて信号線路導体１ｂに接続されていることを特徴とするものである。このことにより、電子部品７の端子に接続された信号線路導体１ｂと信号端子２との接合部での特性インピーダンスのずれを小さくできるので、高周波信号の反射損失を小さくすることができ、高周波での作動が良好な電子装置となる。   The electronic device of the present invention is characterized in that the electronic component 7 is mounted on the electronic component mounting package of the present invention and is connected to the signal line conductor 1b. As a result, the deviation in characteristic impedance at the joint between the signal line conductor 1b connected to the terminal of the electronic component 7 and the signal terminal 2 can be reduced, so that the reflection loss of the high frequency signal can be reduced and It becomes an electronic device with good operation.

配線基板１は、例えば図１に示す例では、配線導体として基板１ａの上面には高周波信号を伝送するとともに信号端子２・２が接続される信号線路導体１ｂと、電子部品７が搭載されるとともに電子部品７の下面の接地電極が接続される接地用導体１ｃとが形成され、下面には配線基板１を基体４に搭載して接続するための搭載用導体１ｄが形成されている。接地用導体１ｃと搭載用導体１ｄとは、基板１ａの側面に形成された、または基板１ａを貫通して形成された接続導体により接続される。また、図７および図８に示す例では、配線導体として、信号端子２の端面が対向する段差部１ｅの側面に、信号端子２がろう材３により接続される側面導体１ｆがさらに形成されている。このような配線導体は、電子部品７によりその接続が異なるので、それに応じて形成されるものである。   In the example shown in FIG. 1, for example, the wiring board 1 has a signal line conductor 1 b that transmits a high-frequency signal as a wiring conductor and is connected to the signal terminals 2 and 2, and an electronic component 7. In addition, a grounding conductor 1c to which the ground electrode on the lower surface of the electronic component 7 is connected is formed, and a mounting conductor 1d for mounting and connecting the wiring board 1 to the base 4 is formed on the lower surface. The grounding conductor 1c and the mounting conductor 1d are connected by a connection conductor formed on the side surface of the substrate 1a or formed through the substrate 1a. In the example shown in FIGS. 7 and 8, a side conductor 1f is further formed as a wiring conductor on the side face of the stepped portion 1e where the end face of the signal terminal 2 is opposed to the signal terminal 2 by the brazing material 3. Yes. Such a wiring conductor is formed according to the connection of the electronic component 7 because the connection is different.

また、電子部品７と配線導体とは例えばボンディングワイヤ８により接続されるが、このボンディングワイヤ８を短くすることによって高周波信号の伝送損失を少なくするために、例えば図１に示すように信号線路導体１ｂを信号端子２と電子部品７との間で屈曲した形状として、ボンディングワイヤ８の接続位置が電子部品７にできるだけ近くなるようにしてもよい。なお、信号線路導体１ｂを屈曲させる場合には、例えば図１に示すように屈曲角度が90°より大きくなるように段階的に屈曲させたり、屈曲する角部に丸みをつけたりすると、屈曲部での反射による高周波信号の損失を少なくすることができるので好ましい。信号線路導体１ｂを段階的に屈曲させる場合は、屈曲角度を120°以上とすると、高周波信号の損失がより少なくなるのでより好ましい。   The electronic component 7 and the wiring conductor are connected by, for example, a bonding wire 8. In order to reduce the transmission loss of the high-frequency signal by shortening the bonding wire 8, for example, as shown in FIG. The connecting position of the bonding wire 8 may be as close as possible to the electronic component 7 by bending 1b between the signal terminal 2 and the electronic component 7. When the signal line conductor 1b is bent, for example, as shown in FIG. 1, if the bending angle is bent stepwise so that the bending angle becomes larger than 90 °, or the bent corner is rounded, This is preferable because the loss of the high-frequency signal due to the reflection can be reduced. When the signal line conductor 1b is bent stepwise, it is more preferable that the bending angle be 120 ° or more because the loss of the high-frequency signal is reduced.

配線基板１の段差部１ｅの底面から信号線路導体１ｂの上面までの高さは、信号端子２の径（厚み）に応じて設定する。この高さを、最大で信号端子２の径（厚み）と等しくすることで、配線基板１の側面側から見て信号端子２と信号線路導体１ｂの上面とが重なるように配置すると、信号端子２の表面から信号線路導体１ｂの上面へ伝送される信号が屈曲する幅が信号端子の厚みまでに抑えられ、信号の反射損失が抑えられるので好ましい。上述したように、配線基板１の側面側から見て信号端子２の中心と信号線路導体１ｂの上面とが重なるように配置するのがより好ましく、この場合は、この高さを信号端子２の厚みの１／２とすればよい。   The height from the bottom surface of the stepped portion 1 e of the wiring board 1 to the top surface of the signal line conductor 1 b is set according to the diameter (thickness) of the signal terminal 2. When this height is made equal to the diameter (thickness) of the signal terminal 2 at the maximum, the signal terminal 2 and the upper surface of the signal line conductor 1b are arranged so as to overlap each other when viewed from the side surface side of the wiring board 1. The width at which the signal transmitted from the surface 2 to the upper surface of the signal line conductor 1b bends is suppressed to the thickness of the signal terminal, which is preferable because the signal reflection loss is suppressed. As described above, it is more preferable that the center of the signal terminal 2 and the upper surface of the signal line conductor 1b overlap with each other when viewed from the side of the wiring board 1, and in this case, the height of the signal terminal 2 is What is necessary is just to set it as 1/2 of thickness.

図９（ａ）は、図８に示す例の配線基板１を段差部１ｅ側から見た側面図であり、図９（ｂ）〜（ｄ）は、それぞれ他の例を示す図９（ａ）と同様の側面図である。これらの図においては、側面導体１ｆの形状等が分かりやすいように、信号端子２およびろう材３を省略している。   FIG. 9A is a side view of the wiring substrate 1 of the example shown in FIG. 8 as viewed from the stepped portion 1e side, and FIGS. 9B to 9D are views of other examples, respectively. ) Is a side view similar to FIG. In these drawings, the signal terminal 2 and the brazing material 3 are omitted so that the shape and the like of the side conductor 1f can be easily understood.

側面導体１ｆは、信号端子２の端面が対向する段差部１ｅの側面に形成されていれば、信号端子２とろう材３により接続することで信号端子２と信号線路導体１ｂとの接続の補強となるので、側面導体１ｆは、図９（ｄ）に示す例のように、信号線路導体１ｂと接続されていなくてもよいし、図９（ａ）〜（ｃ）に示す例のように、信号線路導体１ｂと接続されていてもよい。図９（ｄ）に示す例のように、側面導体１ｆが信号線路導体１ｂから離れて信号の伝送経路がろう材３の部分で分岐した形状になると、この部分で信号の反射が発生して損失が大きくなる場合があるので、図９（ａ）〜（ｃ）に示す例のように、側面導体１ｆは信号線路導体１ｂから連続して形成されて接続されているのが好ましい。   If the side surface conductor 1f is formed on the side surface of the stepped portion 1e where the end surface of the signal terminal 2 faces, the connection between the signal terminal 2 and the signal line conductor 1b is reinforced by connecting the signal terminal 2 and the brazing material 3 to each other. Therefore, the side conductor 1f may not be connected to the signal line conductor 1b as in the example shown in FIG. 9D, or as in the examples shown in FIGS. 9A to 9C. The signal line conductor 1b may be connected. If the side conductor 1f is separated from the signal line conductor 1b and the signal transmission path branches off at the brazing filler metal 3 portion as shown in FIG. 9D, signal reflection occurs at this portion. Since the loss may increase, the side conductor 1f is preferably formed continuously from the signal line conductor 1b and connected as in the example shown in FIGS. 9 (a) to 9 (c).

また、図９（ａ）〜（ｃ）に示す例のように、信号端子２と信号線路導体１ｂとの接合を補強し、信号の反射を抑えるためには、段差部１ｅの側面の信号端子２の端面が対向する領域（側面視して信号端子２と重なる領域）に形成されているのが好ましい。信号端子２と信号線路導体１ｂとの接合を補強するためには、側面導体１ｆの面積を基板１ａの側面の信号端子２が対向する領域よりもある程度大きくするのが好ましい。   Further, as in the example shown in FIGS. 9A to 9C, in order to reinforce the joint between the signal terminal 2 and the signal line conductor 1b and suppress the signal reflection, the signal terminal on the side surface of the step portion 1e. 2 is preferably formed in a region where the two end faces are opposed to each other (a region overlapping the signal terminal 2 in a side view). In order to reinforce the bonding between the signal terminal 2 and the signal line conductor 1b, it is preferable that the area of the side conductor 1f is made somewhat larger than the area where the signal terminal 2 on the side face of the substrate 1a faces.

このとき、図９（ｂ）および（ｃ）に示す例のように、側面導体１ｆの形状を信号線路導体１ｂの幅に対して両側に同程度拡がった形状にすると、ろう材３による接続を行なう際に、溶融したろう材の表面張力により信号端子２が引っ張られて信号端子２と信号線路導体１ｂとが同一線上からずれてしまうことがないので好ましい。また、信号端子２と側面導体１ｆとの間に形成されるろう材３のフィレット形状や大きさも、信号端子２の両側で同程度となることから、フィレット部に加わる応力が信号端子２の両側で同程度となるので接続信頼性が高くなる。さらに、図９（ｃ）に示す例のように、信号端子２から側面導体１ｆの端部までの距離が均等になるような形状とすると、信号端子２の周囲に形成されるろう材のフィレット形状や大きさが均等になり、フィレット部に応力が集中する部分が生じるのを抑えられることから、接続信頼性がより高くなるので好ましい。   At this time, as in the example shown in FIGS. 9B and 9C, when the shape of the side conductor 1f is expanded to the same extent on both sides with respect to the width of the signal line conductor 1b, the connection by the brazing material 3 is established. When performing, it is preferable because the signal terminal 2 is not pulled by the surface tension of the molten brazing material and the signal terminal 2 and the signal line conductor 1b are not displaced from the same line. In addition, since the fillet shape and size of the brazing material 3 formed between the signal terminal 2 and the side conductor 1f are approximately the same on both sides of the signal terminal 2, stress applied to the fillet portion is applied to both sides of the signal terminal 2. Therefore, connection reliability is improved. Further, as in the example shown in FIG. 9C, if the shape is such that the distance from the signal terminal 2 to the end of the side conductor 1f is uniform, a fillet of brazing material formed around the signal terminal 2 Since the shape and size are equalized, and the occurrence of a portion where stress is concentrated on the fillet portion is suppressed, it is preferable because the connection reliability becomes higher.

また、図９（ｃ）に示す例は、図９（ｂ）と比較すると、側面導体１ｆの面積は同程度であるので補強の効果は同程度であるが、側面導体１ｆの形状が搭載用導体１ｄ（基体４）に近い部分の面積が小さい形状となっていることから、側面導体１ｆに接続された信号端子２と搭載用導体１ｄ（基体４）との間の容量結合の増加がより小さく、インピーダンスの低下が抑えられるので好ましい。   Further, in the example shown in FIG. 9C, compared with FIG. 9B, the area of the side conductor 1f is almost the same, so that the effect of reinforcement is the same, but the shape of the side conductor 1f is the same for mounting. Since the area near the conductor 1d (base 4) has a small shape, the increase in capacitive coupling between the signal terminal 2 connected to the side conductor 1f and the mounting conductor 1d (base 4) is further increased. It is preferable because it is small and the decrease in impedance can be suppressed.

配線基板１は、例えば、比誘電率が9.5の酸化アルミニウム質焼結体から成り、厚みが0.3ｍｍである基板１ａを用いた場合であれば、信号線路導体１ｂの幅を0.3ｍｍとし、厚みを0.002ｍｍとすることにより、信号線路導体１ｂを50Ωにインピーダンス整合させることができる。この配線基板１に直径0.2ｍｍの信号端子２を接続する場合は、基板１ａに高さが0.098ｍｍの段差部１ｅを設けると、配線基板１の側面側から見て信号端子２の中心と信号線路導体１ｂの上面とが重なるように信号端子を配置することができる。   For example, if the wiring board 1 is made of an aluminum oxide sintered body having a relative dielectric constant of 9.5 and a thickness of 0.3 mm, the width of the signal line conductor 1b is set to 0.3 mm. By setting the distance to 0.002 mm, the signal line conductor 1b can be impedance-matched to 50Ω. When the signal terminal 2 having a diameter of 0.2 mm is connected to the wiring board 1, if the step portion 1 e having a height of 0.098 mm is provided on the board 1 a, the center of the signal terminal 2 and the signal are viewed from the side of the wiring board 1. The signal terminal can be arranged so as to overlap the upper surface of the line conductor 1b.

配線基板１は、酸化アルミニウム（アルミナ：Ａｌ２Ｏ３）質焼結体，窒化アルミニウム（ＡｌＮ）質焼結体等のセラミックス絶縁材料等から成る基板１ａに信号線路導体１ｂを含む配線導体が形成されたものである。基板１ａが例えば酸化アルミニウム質焼結体から成る場合であれば、まずアルミナ（Ａｌ２Ｏ３）やシリカ（ＳｉＯ２），カルシア（ＣａＯ），マグネシア（ＭｇＯ）等の原料粉末に適当な有機溶剤，溶媒を添加混合して泥漿状とし、これを周知のドクターブレード法やカレンダーロール法等によりシート状に成形してセラミックグリーンシート（以下、グリーンシートともいう）を得る。その後、グリーンシートを所定形状に打ち抜き加工するとともに必要に応じて複数枚積層して積層体を作製し、これを約1600℃の温度で焼成することにより製作される。 The wiring substrate 1 includes a wiring conductor including a signal line conductor 1b formed on a substrate 1a made of a ceramic insulating material such as an aluminum oxide (alumina: Al 2 O 3 ) sintered body or an aluminum nitride (AlN) sintered body. It has been done. When the substrate 1a is made of, for example, an aluminum oxide sintered body, first, an organic solvent suitable for a raw material powder such as alumina (Al 2 O 3 ), silica (SiO 2 ), calcia (CaO), magnesia (MgO), etc. , A solvent is added and mixed to form a slurry, which is formed into a sheet by a known doctor blade method, calendar roll method, or the like to obtain a ceramic green sheet (hereinafter also referred to as a green sheet). Thereafter, the green sheet is punched into a predetermined shape, and a plurality of laminated sheets are produced as necessary to produce a laminate, which is then fired at a temperature of about 1600 ° C.

基板１ａに段差部１ｅを形成するには、平板状の基板１ａを作製した後に、１辺の外縁部の厚みが薄くなるように研削加工するか、基板１ａに底が平らな面を持つ溝を研削加工により形成して溝部で切断すればよい。あるいは、基板１ａ作製する際に、最上層のグリーンシートを小さいものにするなどして、段差を有する積層体を作製してもよい。   In order to form the stepped portion 1e on the substrate 1a, after forming the flat substrate 1a, the substrate 1a is ground so that the thickness of the outer edge of one side is reduced, or the substrate 1a has a flat bottom surface. May be formed by grinding and cut at the groove. Alternatively, when the substrate 1a is manufactured, a laminate having a step may be manufactured by making the uppermost green sheet small.

信号線路導体１ｂを含む配線導体の形成方法は、基板１ａと同時焼成により、あるいは基板１ａを作製した後に金属メタライズを形成する周知の方法や、基板１ａを作製した後に蒸着法やフォトリソグラフィ法により形成する方法がある。電子装置が小型であり、それに搭載される配線基板１はさらに小さいので、配線導体は微細なものとなるため、信号線路導体１ｂと信号端子２との位置合わせ精度を高めるためには、蒸着法やフォトリソグラフィ法により形成する方法が好ましい。この場合は、配線導体の形成前に必要に応じて基板１ａの主面に研磨加工を施す場合もある。   The wiring conductor including the signal line conductor 1b can be formed by a well-known method of forming metal metallization after the substrate 1a is produced by simultaneous firing with the substrate 1a, or by vapor deposition or photolithography after the substrate 1a is produced. There is a method of forming. Since the electronic device is small and the wiring substrate 1 mounted on the electronic device is smaller, the wiring conductor becomes fine. Therefore, in order to increase the alignment accuracy between the signal line conductor 1b and the signal terminal 2, a vapor deposition method is used. Or a method of forming by photolithography. In this case, polishing may be performed on the main surface of the substrate 1a as necessary before the formation of the wiring conductor.

段差部１ｅを有する基板１ａの上に蒸着法により薄膜導体を全面に形成した後、フォトリソグラフィ法により信号線路導体１ｂ等の配線導体を形成する場合は、段差部１ｅに合わせた３次元構造の金属製のマスクを用いることにより、段差部１ｅの側面上でもマスクと薄膜導体とを密着させることができ、精度よく側面導体１ｆを形成することができる。   When a thin film conductor is formed on the entire surface of the substrate 1a having the stepped portion 1e by vapor deposition, and then a wiring conductor such as the signal line conductor 1b is formed by photolithography, a three-dimensional structure matching the stepped portion 1e is formed. By using a metal mask, the mask and the thin film conductor can be brought into close contact with each other even on the side surface of the stepped portion 1e, and the side conductor 1f can be formed with high accuracy.

以下、配線導体を蒸着法やフォトリソグラフィ法により形成する場合について詳細に説明する。配線導体は、例えば密着金属層，拡散防止層および主導体層が順次積層された３層構造の導体層から成る。   Hereinafter, the case where the wiring conductor is formed by vapor deposition or photolithography will be described in detail. The wiring conductor is composed of a conductor layer having a three-layer structure in which, for example, an adhesion metal layer, a diffusion prevention layer, and a main conductor layer are sequentially laminated.

密着金属層は、セラミックス等から成る基板１ａとの密着性を良好とするという観点からは、チタン（Ｔｉ），クロム（Ｃｒ），タンタル（Ｔａ），ニオブ（Ｎｂ），ニッケル−クロム（Ｎｉ−Ｃｒ）合金，窒化タンタル（Ｔａ２Ｎ）等の熱膨張率がセラミックスと近い金属のうちの少なくとも１種より成るのが好ましく、その厚みは0.01〜0.2μｍ程度が好ましい。密着金属層の厚みが0.01μｍ未満では、密着金属層を基板１ａに強固に密着させることが困難となる傾向がある。一方、密着金属層の厚みが0.2μｍを超えると、成膜時の内部応力によって密着金属層が基板１ａから剥離し易くなる傾向がある。 From the viewpoint of improving the adhesion with the substrate 1a made of ceramics or the like, the adhesion metal layer is made of titanium (Ti), chromium (Cr), tantalum (Ta), niobium (Nb), nickel-chromium (Ni-). It is preferable that the thermal expansion coefficient is at least one of metals close to that of ceramics, such as a Cr) alloy and tantalum nitride (Ta 2 N), and the thickness is preferably about 0.01 to 0.2 μm. If the thickness of the adhesion metal layer is less than 0.01 μm, it tends to be difficult to firmly adhere the adhesion metal layer to the substrate 1a. On the other hand, if the thickness of the adhesion metal layer exceeds 0.2 μm, the adhesion metal layer tends to be peeled off from the substrate 1a due to internal stress during film formation.

拡散防止層は、密着金属層と主導体層との相互拡散を防ぐという観点からは、白金（Ｐｔ），パラジウム（Ｐｄ），ロジウム（Ｒｈ），ニッケル（Ｎｉ），Ｎｉ−Ｃｒ合金，Ｔｉ−Ｗ合金等の熱伝導性の良好な金属のうち少なくとも１種より成ることが好ましく、その厚みは0.05〜１μｍ程度が好ましい。拡散防止層の厚みが0.05μｍ未満では、ピンホール等の欠陥が発生して拡散防止層としての機能を果たしにくくなる傾向があり、１μｍを超えると、成膜時の内部応力により拡散防止層が密着金属層から剥離し易く成る傾向がある。なお、拡散防止層にＮｉ−Ｃｒ合金を用いる場合は、Ｎｉ−Ｃｒ合金は基板１ａとの密着性が良好なため、密着金属層を省くことも可能である。   From the viewpoint of preventing mutual diffusion between the adhesion metal layer and the main conductor layer, the diffusion prevention layer is platinum (Pt), palladium (Pd), rhodium (Rh), nickel (Ni), Ni—Cr alloy, Ti— It is preferably made of at least one metal having good thermal conductivity such as W alloy, and the thickness is preferably about 0.05 to 1 μm. If the thickness of the diffusion prevention layer is less than 0.05 μm, defects such as pinholes tend to be generated, making it difficult to perform the function as the diffusion prevention layer. If the thickness exceeds 1 μm, the diffusion prevention layer is caused by internal stress during film formation. There is a tendency to easily peel from the adhesion metal layer. When a Ni—Cr alloy is used for the diffusion preventing layer, the Ni—Cr alloy has good adhesion to the substrate 1a, so that the adhesion metal layer can be omitted.

主導体層は、電気抵抗の小さい金（Ａｕ），Ｃｕ，Ｎｉ，銀（Ａｇ）の少なくとも１種より成ることが好ましく、その厚みは0.1〜５μｍ程度が好ましい。主導体層の厚みが0.1μｍ未満では、電気抵抗が大きなものとなって配線基板１の配線導体に要求される電気抵抗を満足できなくなる傾向があり、５μｍを超えると、成膜時の内部応力により主導体層が拡散防止層から剥離し易く成る傾向がある。また、Ｃｕは酸化し易いので、その上にＮｉおよびＡｕからなる保護層を被覆してもよい。   The main conductor layer is preferably made of at least one of gold (Au), Cu, Ni, and silver (Ag) having a low electric resistance, and the thickness is preferably about 0.1 to 5 μm. If the thickness of the main conductor layer is less than 0.1 μm, the electric resistance tends to be large and the electric resistance required for the wiring conductor of the wiring board 1 tends not to be satisfied. Therefore, the main conductor layer tends to be easily peeled off from the diffusion preventing layer. Further, since Cu is easily oxidized, a protective layer made of Ni and Au may be coated thereon.

信号端子２は、Ｆｅ−Ｎｉ−Ｃｏ合金やＦｅ−Ｎｉ合金等の金属から成る。例えば信号端子２がＦｅ−Ｎｉ−Ｃｏ合金から成る場合は、Ｆｅ−Ｎｉ−Ｃｏ合金のインゴット（塊）に圧延加工や打ち抜き加工あるいは引き抜き加工や押し出し加工等の周知の金属加工方法を施すことによって、長さが1.5〜22ｍｍで直径が0.1〜１ｍｍの線状に製作される。信号端子２の強度を確保しながら、基体４に形成された貫通孔４ｃに充填された封止材５を貫通して固定した状態でより高いインピーダンスでのマッチングを行ないつつ小型にするには、信号端子２の直径は0.15〜0.6ｍｍが好ましい。信号端子２の直径が0.15ｍｍより細くなると、電子部品搭載用パッケージを実装する場合の取り扱いで信号端子２が曲がりやすくなり、作業性が低下しやすくなる。また、直径が0.6ｍｍより太くなると、インピーダンス整合させた場合の貫通孔１ｃの径が信号端子２の径に伴い大きくなるので、製品の小型化に向かないものとなってしまう。   The signal terminal 2 is made of a metal such as an Fe—Ni—Co alloy or an Fe—Ni alloy. For example, when the signal terminal 2 is made of an Fe—Ni—Co alloy, a known metal working method such as rolling, stamping, drawing or extruding is applied to the ingot of the Fe—Ni—Co alloy. It is manufactured in a linear shape with a length of 1.5-22 mm and a diameter of 0.1-1 mm. In order to make the signal terminal 2 small while performing matching with a higher impedance in a state where the sealing material 5 filled in the through hole 4c formed in the base body 4 is fixed while securing the strength of the signal terminal 2, The diameter of the signal terminal 2 is preferably 0.15 to 0.6 mm. When the diameter of the signal terminal 2 is smaller than 0.15 mm, the signal terminal 2 is easily bent by handling when mounting the electronic component mounting package, and the workability is easily lowered. On the other hand, if the diameter is larger than 0.6 mm, the diameter of the through hole 1c when impedance matching is increased with the diameter of the signal terminal 2, which is not suitable for downsizing of the product.

また、図６に図３と同様の断面図で示すように、信号端子２は、貫通孔１ｃから突出した部分において、配線基板１の側面側から見て信号線路導体１ｂとの接続部側の端部にかけて細くなる（厚みが薄くなる）形状であるのが好ましい。このような形状にすると、信号端子２の端部におけるインピーダンスの変化が緩やかになるとともに、十分な接合強度が得られるようなろう材３のフィレット形状にしても、信号線路導体１ｂの上のろう材３の厚みを薄くすることができるので、インピーダンスの低下がより少なくなり、高周波信号の反射損失が小さく伝送特性が良好な接続構造とすることができる。また、信号線路導体１ｂの上のろう材３の厚みを薄くしつつ、信号端子２とろう材３とが接続される面積を増加させることができるので、信号端子２と信号線路導体１ｂとの接続強度が向上し、接続信頼性に優れた接続構造とすることができる。   Further, as shown in the cross-sectional view similar to FIG. 3 in FIG. 6, the signal terminal 2 has a portion protruding from the through hole 1 c on the side of the connection portion with the signal line conductor 1 b when viewed from the side surface side of the wiring board 1. A shape that becomes thinner (thinner thickness is reduced) is preferable. With such a shape, the change in impedance at the end of the signal terminal 2 becomes gradual, and the brazing material 3 has a fillet shape so that sufficient bonding strength can be obtained. Since the thickness of the material 3 can be reduced, it is possible to obtain a connection structure in which the decrease in impedance is reduced, the reflection loss of high-frequency signals is small, and the transmission characteristics are good. Moreover, since the area where the signal terminal 2 and the brazing material 3 are connected can be increased while reducing the thickness of the brazing material 3 on the signal line conductor 1b, the signal terminal 2 and the signal line conductor 1b can be connected to each other. The connection strength is improved, and a connection structure with excellent connection reliability can be obtained.

図６に示す例のように、配線基板１の側面側から見て信号端子２の中心と信号線路導体１ｂの上面とが重なるように配置されている場合は、信号端子２の端部を上下から中心に向かって同程度薄くなるようにすればよい。信号端子２の中心が信号線路導体１ｂの上面とずれて配置される場合は、信号端子２の上下から信号線路導体１ｂの上面に向かって薄くなるようにすればよい。   When the center of the signal terminal 2 and the upper surface of the signal line conductor 1b overlap with each other when viewed from the side of the wiring board 1 as in the example shown in FIG. It may be as thin as about from the center to the center. When the center of the signal terminal 2 is shifted from the upper surface of the signal line conductor 1b, the signal terminal 2 may be thinned from the upper and lower sides of the signal terminal 2 toward the upper surface of the signal line conductor 1b.

信号端子２の端部を薄くするのは、線状に形成した信号端子２の端部をプレス加工や研削加工することによって可能である。   The end of the signal terminal 2 can be thinned by pressing or grinding the end of the signal terminal 2 formed in a linear shape.

図１に示すような電子部品搭載用パッケージの場合は、まず、信号端子２を基体４に形成された貫通孔４ｃに充填された封止材５を貫通して固定する。そして、例えば金−ゲルマニウム（Ａｕ−Ｇｅ）合金等のプリフォームやペースト状の接合材を搭載部４ａの上に載置し、その上に配線基板１の段差部１ｅの底面を信号端子２の側面に接するようにして配置して加熱することにより配線基板１を基体４の搭載部４ａ上に接合して搭載した後に、信号端子２と信号線路導体１ｂとをろう材３で接続する。接合材とろう材３とに同じものを用い、配線基板１の搭載部４ａへの接合と信号端子２と信号線路導体１ｂとの接続を同時に行なってもよい。   In the case of the electronic component mounting package as shown in FIG. 1, first, the signal terminal 2 is fixed by penetrating the sealing material 5 filled in the through hole 4 c formed in the base 4. Then, for example, a preform such as a gold-germanium (Au—Ge) alloy or a paste-like bonding material is placed on the mounting portion 4 a, and the bottom surface of the stepped portion 1 e of the wiring board 1 is placed on the mounting portion 4 a. The wiring board 1 is bonded and mounted on the mounting portion 4 a of the base 4 by being placed in contact with the side surface and heated, and then the signal terminal 2 and the signal line conductor 1 b are connected by the brazing material 3. The same material may be used for the bonding material and the brazing material 3, and the bonding of the wiring board 1 to the mounting portion 4a and the connection of the signal terminal 2 and the signal line conductor 1b may be performed simultaneously.

信号端子２の搭載部４ａ側の面から搭載面４ｂまでの距離は、配線基板１の段差部１ｅの底面から搭載面４ｂまでの距離に等しく、段差部１ｅの厚みに接合材の厚みを加えたものになる。高周波信号が良好に伝送されるように配線基板１、信号端子２、封止材５、貫通孔４ｃ等を設計した上で、これらに応じて搭載面４ｂの位置を設定する。そして、配線基板１を搭載部４ａに搭載する際に、信号端子２の側面が配線基板１の段差部１ｅの底面に接するように接合材の厚みを調整して配線基板１を搭載部４ａ上に接合して搭載する。   The distance from the surface of the signal terminal 2 on the mounting portion 4a side to the mounting surface 4b is equal to the distance from the bottom surface of the stepped portion 1e of the wiring board 1 to the mounting surface 4b, and the thickness of the stepped portion 1e is added to the thickness of the bonding material. It becomes a thing. The wiring board 1, the signal terminal 2, the sealing material 5, the through hole 4c, and the like are designed so that the high-frequency signal is transmitted satisfactorily, and the position of the mounting surface 4b is set according to these. Then, when mounting the wiring board 1 on the mounting portion 4a, the thickness of the bonding material is adjusted so that the side surface of the signal terminal 2 is in contact with the bottom surface of the stepped portion 1e of the wiring substrate 1, and the wiring substrate 1 is mounted on the mounting portion 4a. Bonded to and mounted.

信号端子２を段差部１ｅの底面に接着する場合は、接着強度が強く、絶縁性である接着剤を用いて接着する。導電性のもので接着すると、接着した部分では信号端子の見かけ上の幅が大きくなることになるので、反射損失が大きくなってしまう場合があるからである。また、接着剤の比誘電率が大きいとインピーダンスのずれが大きくなるので、接着剤の比誘電率は小さいものが好ましい。このような点から、例えば、エポキシ樹脂やポリアミド樹脂を主成分とする接着剤を用いるとよい。このような樹脂製の接着剤は、加熱硬化型の場合であっても、信号端子２と信号線路導体１ｂとを接続するためのろう材３や配線基板１を基体４に接合するための接合材の融点より低い温度で硬化するものが一般的であるので、配線基板１を基体４上に搭載し、信号端子２と信号線路導体１ｂとを接続した後に接着してもろう材３や接合材を溶融させることがなく、接続信頼性に影響を与えることがないので好ましい。   When the signal terminal 2 is bonded to the bottom surface of the stepped portion 1e, the signal terminal 2 is bonded using an adhesive having high bonding strength and insulation. This is because, when the conductive material is bonded, the apparent width of the signal terminal is increased at the bonded portion, so that the reflection loss may increase. Moreover, since the shift | offset | difference of an impedance will become large when the dielectric constant of an adhesive agent is large, the thing with a small dielectric constant of an adhesive agent is preferable. From such a point, for example, an adhesive mainly composed of an epoxy resin or a polyamide resin may be used. Such a resinous adhesive is a bonding for bonding the brazing material 3 for connecting the signal terminal 2 and the signal line conductor 1b and the wiring board 1 to the base 4 even in the case of the thermosetting type. Since it is generally hardened at a temperature lower than the melting point of the material, even if the wiring board 1 is mounted on the base 4 and the signal terminal 2 and the signal line conductor 1b are connected and then bonded, the brazing material 3 or bonding It is preferable because the material is not melted and connection reliability is not affected.

配線基板１の信号線路導体１ｂと信号端子２との距離は、できるだけ小さくする（例えば0.15ｍｍ以下）と、損失が小さくなるので好ましい。この場合は、例えば、信号線路導体１ｂと信号端子２との間をつなぐようにろう材３として金−錫（Ａｕ−Ｓｎ）合金等の半田のペーストをシリンジで塗布するか、金−錫合金半田リボンを載置した後に、窒素中で半田が溶融する330℃程度まで加熱することで接続できる。配線基板１の段差部１ｅの側面を固定された信号端子２の端部に突き当てるようにして配線基板１を配置した後にろう材３で接続すると信号線路導体１ｂと信号端子２との距離を小さくすることができる。一方、配線基板１と信号端子２との距離が大きい場合には、信号線路導体１ｂおよび信号端子２のそれぞれの接合部側の端部に予めろう材３として金−錫合金を形成しておき、それらをつなぐようにして同じくろう材３として金−錫合金等から成る半田リボンを載置し、窒素中で金錫合金半田が溶融する330℃程度まで加熱することで接続できる。このとき、予め形成しておく金−錫合金を共晶組成にしておき、金−錫合金半田リボンを共晶温度より高い温度で溶融する組成にしておくと、両方の端をなだらかな形状にして接続できるので、高周波特性のよい接続部とすることができる。信号線路導体１ｂおよび信号端子２の端部に予め金−錫合金を形成するには、これらの上にそれぞれ金−錫合金半田のペーストを塗布して加熱することにより行なえばよい。   It is preferable to make the distance between the signal line conductor 1b and the signal terminal 2 of the wiring board 1 as small as possible (for example, 0.15 mm or less) because loss is reduced. In this case, for example, a solder paste such as a gold-tin (Au—Sn) alloy is applied as a brazing material 3 with a syringe so as to connect between the signal line conductor 1 b and the signal terminal 2, or a gold-tin alloy. After placing the solder ribbon, it can be connected by heating to about 330 ° C. where the solder melts in nitrogen. When the wiring board 1 is arranged so that the side surface of the stepped portion 1e of the wiring board 1 abuts against the end of the fixed signal terminal 2 and then connected with the brazing material 3, the distance between the signal line conductor 1b and the signal terminal 2 is increased. Can be small. On the other hand, when the distance between the wiring board 1 and the signal terminal 2 is large, a gold-tin alloy is previously formed as the brazing material 3 at the end of each of the signal line conductor 1b and the signal terminal 2 on the joint portion side. Similarly, a solder ribbon made of gold-tin alloy or the like is placed as the brazing material 3 so as to connect them, and can be connected by heating to about 330 ° C. at which the gold-tin alloy solder melts in nitrogen. At this time, if the gold-tin alloy previously formed has a eutectic composition and the gold-tin alloy solder ribbon is melted at a temperature higher than the eutectic temperature, both ends have a gentle shape. Therefore, it is possible to provide a connection portion with good high frequency characteristics. In order to form the gold-tin alloy in advance on the ends of the signal line conductor 1b and the signal terminal 2, it is only necessary to apply and heat a gold-tin alloy solder paste on them.

基体４は、上面の中央部に電子部品７の搭載部４ａを有するとともに搭載された電子部品７が発生する熱をパッケージの外部に放散する機能を有する。このため、基体４は、熱伝導性の良い金属から成り、搭載される電子部品７やセラミック製の配線基板１の熱膨張係数に近いものやコストの安いものとして、例えば、Ｆｅ99.6質量％−Ｍｎ0.4質量％系のＳＰＣ（Steel Plate Cold）材や、Ｆｅ−Ｎｉ−Ｃｏ合金やＦｅ−Ｍｎ合金等から選ばれる。例えば基体４がＦｅ−Ｍｎ合金から成る場合は、Ｆｅ−Ｍｎ合金のインゴット（塊）に圧延加工や打ち抜き加工等の周知の金属加工方法を施すことによって所定形状に製作され、貫通孔１ｃはドリル加工や金型による打ち抜き加工により形成される。また、基体４が搭載部４ａとして突出部を有する形状の場合は、切削加工やプレス加工により形成することができる。   The base 4 has a mounting portion 4a for the electronic component 7 in the center of the upper surface and has a function of radiating heat generated by the mounted electronic component 7 to the outside of the package. For this reason, the base 4 is made of a metal having good thermal conductivity, and is close to the thermal expansion coefficient of the electronic component 7 or ceramic wiring board 1 to be mounted or has a low cost. For example, Fe 99.6% by mass -Mn 0.4 mass% SPC (Steel Plate Cold) material, Fe-Ni-Co alloy, Fe-Mn alloy, or the like. For example, when the substrate 4 is made of an Fe—Mn alloy, the ingot (lumb) of the Fe—Mn alloy is manufactured to a predetermined shape by applying a known metal processing method such as rolling or punching, and the through hole 1c is drilled. It is formed by machining or punching with a mold. Moreover, when the base | substrate 4 is a shape which has a protrusion part as the mounting part 4a, it can form by cutting or press work.

基体４の形状は、通常は厚みが0.5〜２ｍｍの平板状であり、その形状は特に制限はないが、例えば直径が３〜10ｍｍの円板状，半径が1.5〜８ｍｍの円周の一部を切り取った半円板状，一辺が３〜15ｍｍの四角板状等であり、上面から下面にかけて形成された直径が0.6〜2.65ｍｍの貫通孔１ｃを複数有する。図１〜図６に示す例では、２つの貫通孔１ｃを有する基体４に１個の電子部品７を搭載しているが、複数の電子部品７を搭載したり、電子部品７の数や電子部品７の端子の数に応じて信号端子２を固定する貫通孔１ｃを２つより多く形成したりしても構わない。   The shape of the substrate 4 is usually a flat plate having a thickness of 0.5 to 2 mm, and the shape is not particularly limited, but for example, a disk having a diameter of 3 to 10 mm and a part of a circumference having a radius of 1.5 to 8 mm. And a plurality of through holes 1c having a diameter of 0.6 to 2.65 mm formed from the upper surface to the lower surface. In the example shown in FIGS. 1 to 6, one electronic component 7 is mounted on the base body 4 having two through holes 1 c, but a plurality of electronic components 7, the number of electronic components 7, and the number of electronic components 7 Depending on the number of terminals of the component 7, more than two through holes 1c for fixing the signal terminal 2 may be formed.

基体４の厚みは0.5ｍｍ以上２ｍｍ以下が好ましい。基体４の厚みが0.5ｍｍ未満の場合は、電子部品７を保護するための金属製の蓋体９を金属製の基体４の上面に接合する際に、接合温度等の接合条件により基体４が曲がったりして変形し易くなる。一方、基体４の厚みが２ｍｍを超えると、電子部品搭載用パッケージや電子装置の厚みが不要に厚いものとなり、小型化し難くなる。   The thickness of the substrate 4 is preferably 0.5 mm or more and 2 mm or less. When the thickness of the substrate 4 is less than 0.5 mm, when the metal lid 9 for protecting the electronic component 7 is bonded to the upper surface of the metal substrate 4, the substrate 4 is bonded depending on the bonding conditions such as the bonding temperature. It becomes easy to bend and deform. On the other hand, when the thickness of the substrate 4 exceeds 2 mm, the thickness of the electronic component mounting package or the electronic device becomes unnecessarily thick, and it is difficult to reduce the size.

また、基体４の表面には、耐食性に優れ、電子部品７や配線基板１あるいは蓋体９を接合し固定するためのろう材との濡れ性に優れた、厚さが0.5〜９μｍのＮｉ層と厚さが0.5〜５μｍのＡｕ層とをめっき法により順次被着させておくのがよい。これにより、基体４が酸化腐食するのを有効に防止できるとともに、電子部品７や配線基板１あるいは蓋体９を基体４に良好にろう付けすることができる。   Further, a Ni layer having a thickness of 0.5 to 9 μm is excellent on the surface of the base body 4 with excellent corrosion resistance, excellent wettability with a brazing material for joining and fixing the electronic component 7, the wiring board 1 or the lid 9. And an Au layer having a thickness of 0.5 to 5 μm are preferably sequentially deposited by a plating method. Thereby, it is possible to effectively prevent the base 4 from being oxidatively corroded, and the electronic component 7, the wiring board 1 or the lid 9 can be brazed to the base 4 satisfactorily.

基体４に形成された貫通孔１ｃには、封止材５が充填されており、この封止材５を貫通して信号端子２が固定されている。信号端子２は、一方の端部（上端部）は基体４の上面から２ｍｍ程度まで突出させて固定される。一方、信号端子２の他方の端部（下端部）は、外部電気回路（図示せず）に接続するために基体４の下面から１〜20ｍｍ程度突出しているのが好ましい。こうして、図１に示す例のように、信号端子２の上端部と電子部品７とを電気的に接続するとともに、信号端子２の下端部を外部電気回路（図示せず）に電気的に接続することにより、信号端子２は電子部品７と外部電気回路との間で高周波の入出力信号を伝送する機能を果たす。   A through hole 1 c formed in the base 4 is filled with a sealing material 5, and the signal terminal 2 is fixed through the sealing material 5. The signal terminal 2 is fixed with one end (upper end) protruding from the upper surface of the base 4 to about 2 mm. On the other hand, it is preferable that the other end (lower end) of the signal terminal 2 protrudes from the lower surface of the base 4 by about 1 to 20 mm in order to connect to an external electric circuit (not shown). Thus, as in the example shown in FIG. 1, the upper end of the signal terminal 2 and the electronic component 7 are electrically connected, and the lower end of the signal terminal 2 is electrically connected to an external electric circuit (not shown). Thus, the signal terminal 2 functions to transmit high-frequency input / output signals between the electronic component 7 and the external electric circuit.

封止材５は、ガラスやセラミックスなどの絶縁性の無機材料から成り、信号端子２と基体４との絶縁間隔を確保するとともに、信号端子２を基体４の貫通孔１ｃ内に固定する機能を有する。このような封止材５の例としては、ホウケイ酸ガラス，ソーダガラス等のガラスおよびこれらのガラスに封止材５の熱膨張係数や比誘電率を調整するためのセラミックフィラーを加えたものが挙げられ、インピーダンスマッチングのためにその比誘電率を適宜選択する。比誘電率を低下させるフィラーとしては、酸化リチウム等が挙げられる。例えば、特性インピーダンスを50Ωとするには、貫通孔１ｃの内径が1.75ｍｍで信号端子２の外径が0.2ｍｍの場合、あるいは貫通孔１ｃの内径が2.2ｍｍで信号端子２の外径が0.25ｍｍの場合であれば、封止材５の比誘電率が6.8であるものを用いればよい。また、貫通孔１ｃの内径が1.65ｍｍで信号端子２の外径が0.25ｍｍの場合であれば、封止材５の比誘電率が５であるものを用いればよい。   The sealing material 5 is made of an insulating inorganic material such as glass or ceramics, and has a function of securing an insulating interval between the signal terminal 2 and the base 4 and fixing the signal terminal 2 in the through hole 1 c of the base 4. Have. Examples of such a sealing material 5 include glass such as borosilicate glass and soda glass, and those added with a ceramic filler for adjusting the thermal expansion coefficient and relative dielectric constant of the sealing material 5. The relative dielectric constant is appropriately selected for impedance matching. Examples of the filler that lowers the dielectric constant include lithium oxide. For example, in order to set the characteristic impedance to 50Ω, the inner diameter of the through hole 1c is 1.75 mm and the outer diameter of the signal terminal 2 is 0.2 mm, or the inner diameter of the through hole 1c is 2.2 mm and the outer diameter of the signal terminal 2 is 0.25. In the case of mm, the sealing material 5 having a relative dielectric constant of 6.8 may be used. Further, when the inner diameter of the through hole 1c is 1.65 mm and the outer diameter of the signal terminal 2 is 0.25 mm, the sealing material 5 having a relative dielectric constant of 5 may be used.

信号端子２を貫通孔１ｃに充填された封止材５を貫通して固定するには、例えば、封止材５がガラスから成る場合は、周知の粉体プレス法や押し出し成形法を用いてガラス粉末を成形して、内径を信号端子２の外径に合わせ、外径を貫通孔１ｃの内径に合わせた筒状の成形体を作製し、この封止材５の成形体を貫通孔１ｃに挿入し、さらに信号端子２をこの封止材５の孔に挿通し、しかる後、所定の温度に加熱して封止材５を溶融させた後、冷却して固化させることにより行なうことができる。これにより、封止材５により貫通孔１ｃが気密に封止されるとともに、封止材５によって信号端子２が基体４と絶縁されて固定され、同軸線路が形成される。   To fix the signal terminal 2 through the sealing material 5 filled in the through hole 1c, for example, when the sealing material 5 is made of glass, a known powder pressing method or extrusion molding method is used. A glass powder is molded to make a cylindrical molded body whose inner diameter is matched with the outer diameter of the signal terminal 2 and whose outer diameter is matched with the inner diameter of the through hole 1c, and the molded body of the sealing material 5 is formed into the through hole 1c. The signal terminal 2 is inserted into the hole of the sealing material 5 and then heated to a predetermined temperature to melt the sealing material 5 and then cooled and solidified. it can. Thus, the through hole 1c is hermetically sealed by the sealing material 5, and the signal terminal 2 is insulated and fixed by the sealing material 5 from the base body 4, thereby forming a coaxial line.

However, the electronic component mounting package of the present invention is illustrated in FIGS. It may be a box-type electronic component mounting package as shown. 7 is a perspective view showing another example of the embodiment of the electronic component mounting package of the present invention, and FIG. 8 is a cross-sectional view showing an example of a cross section taken along the line AA in FIG. 9 is an enlarged cross-sectional view of a portion B (connection portion) in FIG. 7-9, 4e is the frame part of the base | substrate 4, 4f is the cylindrical part of the base | substrate 4, 5a is a tubular member, 11 is a translucent member.

図７〜図９に示す例の電子部品搭載用パッケージは、基体４の上に搭載部４ａが設けられ、この搭載部４ａを囲むように搭載部４ａの搭載面４ｂに略垂直な枠部４ｅが設けられている。配線基板１は搭載部４ａの搭載面４ｂの上に搭載され、信号端子２は枠部４ｅに形成された貫通孔４ｃ内に封止材５により固定されている。そして、この信号端子２と配線基板１の主面上の信号線路導体１ｂとがろう材３によって電気的に接続され、本発明の信号端子２と信号線路導体１ｂとの接続構造となっている。   The electronic component mounting package of the example shown in FIGS. 7 to 9 is provided with a mounting portion 4a on the base 4, and a frame portion 4e substantially perpendicular to the mounting surface 4b of the mounting portion 4a so as to surround the mounting portion 4a.

枠部４ｅは、基体４と同様の金属のインゴットを圧延加工，打ち抜き加工，切削加工など周知の金属加工法を用いて作製した枠体を銀ろう等の接合材で基体４に接合することによって形成される。また、例えばメタル・インジェクション・モールド法等によって枠部４ｅを基体４と一体的に形成してもよい。   The frame portion 4e is formed by joining a frame body made by using a known metal working method such as rolling, punching, cutting, etc., to the base 4 using a joining material such as silver brazing. It is formed. Further, the frame portion 4e may be formed integrally with the base body 4 by, for example, a metal injection molding method or the like.

Therefore, the direction in which the thickness of the end portion of the signal terminal 2 is reduced is not shifted.

図７に示す例の場合の配線基板１は、図１に示す例の配線基板１と同様にして作製されるが、配線基板１の一方の主面には電子部品７は搭載されないので信号線路導体１ｂのみが形成され、この信号線路導体１ｂと接地導体として機能する他方の主面側の搭載用導体１ｄとでマイクロストリップ線路を構成している。   The wiring board 1 in the case of the example shown in FIG. 7 is manufactured in the same manner as the wiring board 1 of the example shown in FIG. 1, but the electronic component 7 is not mounted on one main surface of the wiring board 1, so that the signal line Only the conductor 1b is formed, and the signal line conductor 1b and the mounting conductor 1d on the other main surface functioning as a ground conductor constitute a microstrip line.

For example, a metal holder in which an optical isolator connected to an external circuit and an optical fiber are bonded with a resin adhesive is fixed to the outer end face of the cylindrical portion 4f by YAG laser welding or the like.

この例では電子部品７は基体４の搭載部４ａに直接搭載されているが、これは電子部品７で発生した熱を金属製の基体４の搭載部４ａを通して外部へ放熱するためである。電子部品７の発熱が大きい場合は、電子部品７（および配線基板１）と搭載部４ａとの間にペルチェ素子等を搭載して、電子部品７を冷却するようにしてもよい。   In this example, the electronic component 7 is directly mounted on the mounting portion 4 a of the base 4, which is to radiate the heat generated in the electronic component 7 to the outside through the mounting portion 4 a of the metallic base 4. When the heat generation of the electronic component 7 is large, a Peltier element or the like may be mounted between the electronic component 7 (and the wiring board 1) and the mounting portion 4a to cool the electronic component 7.
