Description

本発明は、絶縁体層と導体パターンが積層された積層体内部に回路素子が形成され、この回路素子が積層体の外表面に形成された端子に接続された積層型電子部品に関するものである。   The present invention relates to a multilayer electronic component in which a circuit element is formed inside a laminate in which an insulator layer and a conductor pattern are laminated, and the circuit element is connected to a terminal formed on the outer surface of the laminate. .

従来の電子部品に、図6と図7に示す様に、絶縁体層61と導体パターン62を積層して、これらの積層体内にコイルが形成され、積層体の外表面に端子64を形成した積層型電子部品がある。
この種の電子部品が実装される電子機器では、小型化に伴って実装基板とその上部基板やシールドケース等との距離が小さくなっている。この様な電子機器の実装基板に従来の電子部品を実装した場合、上部基板やシールドケースと電子部品の上面に形成された端子が接触し、上部基板やシールドケースとの間でショートしやすかった。
この様な問題を解決するために、図8(A)に示す様に積層体の底面にのみ端子84を形成する(例えば、特許文献1を参照。)か、又は、図8(B)に示す様に積層体の底面と側面に渡って端子84を形成する(例えば、特許文献2を参照。)ことが行われている。
As shown in FIGS. 6 and 7, an insulator layer 61 and a conductor pattern 62 are laminated on a conventional electronic component, and a coil is formed in these laminates, and terminals 64 are formed on the outer surface of the laminate. There are stacked electronic components.
In an electronic device on which this type of electronic component is mounted, the distance between the mounting substrate and the upper substrate, the shield case, and the like is reduced with the miniaturization. When a conventional electronic component is mounted on a mounting board of such an electronic device, the terminal formed on the upper surface of the upper substrate or the shield case and the upper surface of the electronic component is in contact, and it is easy to short-circuit between the upper substrate or the shield case. .
In order to solve such a problem, the terminal 84 is formed only on the bottom surface of the stacked body as shown in FIG. 8A (see, for example, Patent Document 1), or in FIG. As shown, terminals 84 are formed across the bottom and side surfaces of the laminate (see, for example, Patent Document 2).

しかしながら、積層体の底面にのみ端子を形成した従来の電子部品においては、積層体内部の構造が複雑になり、コイルの両端を貫通ビアにて積層体の底面に引き出す必要があった。また、積層体の底面と側面に渡って端子を形成した従来の電子部品においては、コイルの巻軸が実装面と平行になり、低背化した場合、磁束通過面積が小さくなり、特性が劣化するという問題があった。さらに、積層体の底面と側面に渡って端子を形成した従来の電子部品においては、積層体の底面と側面が交差する角部分で端子の厚みが薄くなって、端子が積層体の底面に形成された部分と積層体の側面に形成された部分とに分断され易く、断線が発生したり、直流抵抗が上昇したりするという問題があった。   However, in the conventional electronic component in which the terminal is formed only on the bottom surface of the multilayer body, the structure inside the multilayer body becomes complicated, and it is necessary to draw both ends of the coil to the bottom surface of the multilayer body with through vias. In addition, in conventional electronic components in which terminals are formed across the bottom and side surfaces of the laminate, when the coil winding axis is parallel to the mounting surface and the height is lowered, the magnetic flux passage area is reduced and the characteristics deteriorate. There was a problem to do. Furthermore, in the conventional electronic component in which the terminal is formed across the bottom surface and the side surface of the laminate, the terminal thickness is reduced at the corner portion where the bottom surface and the side surface of the laminate intersect, and the terminal is formed on the bottom surface of the laminate. There is a problem in that breakage is easily generated and a direct current resistance is increased because the portion is easily divided into the formed portion and the portion formed on the side surface of the laminate.

本発明は、積層体の底面と側面に渡って端子を形成した場合でも、断線が発生したり、直流抵抗が上昇したりすることのない積層型電子部品を提供することを目的とする。   An object of the present invention is to provide a multilayer electronic component in which disconnection does not occur and direct current resistance does not increase even when terminals are formed across the bottom and side surfaces of the multilayer body.

本発明は、絶縁体層と導体パターンを積層し、積層体内に回路素子が形成され、回路素子が積層体の外表面に形成された端子に接続された積層型電子部品において、端子は積層体の底面と側面に形成され、積層体の底面に形成された端子と積層体の側面に形成された端子とが積層体内に形成された補助導体で接続される。   The present invention relates to a multilayer electronic component in which an insulator layer and a conductor pattern are laminated, a circuit element is formed in the laminate, and the circuit element is connected to a terminal formed on the outer surface of the laminate. The terminal formed on the bottom surface and the side surface of the multilayer body is connected to the terminal formed on the bottom surface of the multilayer body by the auxiliary conductor formed in the multilayer body.

本発明の積層型電子部品は、絶縁体層と導体パターンを積層し、積層体内に回路素子が形成され、回路素子が接続される端子が積層体の底面と側面に形成され、積層体の底面に形成された端子と積層体の側面に形成された端子とが積層体内に形成された補助導体で接続されるので、断線が発生したり、直流抵抗が上昇したりするのを防止できる。   In the multilayer electronic component of the present invention, an insulator layer and a conductor pattern are laminated, a circuit element is formed in the laminate, and terminals to which the circuit element is connected are formed on the bottom and side surfaces of the laminate, Since the terminal formed on the side of the laminated body and the terminal formed on the side surface of the laminated body are connected by the auxiliary conductor formed in the laminated body, it is possible to prevent disconnection or increase in DC resistance.

本発明の積層型電子部品は、絶縁体層と導体パターンを積層し、絶縁体層間の導体パターンを接続して、積層体内にコイルが形成される。コイルの両端は積層体の側面に引き出されて端子に接続される。端子は積層体の底面と側面に渡って形成される。また、端子の積層体の底面に形成された部分と積層体の側面に形成された部分は積層体内に形成された補助導体で接続される。
従って、本発明の積層型電子部品は、端子を積層体の底面と側面に渡って形成した時に、積層体の底面と側面が交差する角部分で端子の厚みが薄くなった場合でも、補助導体によって、端子の積層体の底面に形成された部分と積層体の側面に形成された部分が確実に接続される。
In the multilayer electronic component of the present invention, an insulator layer and a conductor pattern are laminated, and a conductor pattern between the insulator layers is connected to form a coil in the laminate. Both ends of the coil are drawn out to the side surface of the laminated body and connected to terminals. The terminals are formed across the bottom and side surfaces of the laminate. Further, the portion formed on the bottom surface of the laminated body of the terminal and the portion formed on the side surface of the laminated body are connected by an auxiliary conductor formed in the laminated body.
Therefore, the multilayer electronic component according to the present invention has the auxiliary conductor even when the terminal is formed across the bottom surface and the side surface of the multilayer body, even when the thickness of the terminal is reduced at the corner where the bottom surface and the side surface of the multilayer body intersect. Thus, the portion formed on the bottom surface of the laminated body of the terminal and the portion formed on the side surface of the laminated body are reliably connected.
