Description

本発明は、様々な形状の部品をピックアップしてプリント板に実装するマウンターにおいて、貫通孔などを有する特定の実装部品に対し貼り付けられる吸着用部材を、リフロー後、自動的に剥がし取る実装技術に関する。   The present invention provides a mounting technique for automatically removing a suction member attached to a specific mounting part having a through-hole or the like after reflowing in a mounter that picks up components of various shapes and mounts them on a printed board. About.

従来、一般に、プリント板に電子部品を実装する製造ラインは、半田ペーストの印刷工程から部品実装工程、リフロー炉を通って外観検査機に至る工程など一連の工程で構成されている。部品実装工程は、マウンターにより行っているが、図１１ａに示すように、部品を吸着して実装する場合、実装部品の重心部分をマウンターのエアー吸引ノズル（マウンターノズル）によって吸着し、バランスをとりながら所定の位置まで運んでプリント板に搭載しており、搭載時における部品の脱落や位置ズレを防止している。   Conventionally, a production line for mounting electronic components on a printed board is generally composed of a series of processes such as a solder paste printing process, a component mounting process, a process from a reflow furnace to an appearance inspection machine. Although the component mounting process is performed by a mounter, as shown in FIG. 11a, when the component is sucked and mounted, the center of gravity of the mounted component is sucked by the air suction nozzle (mounter nozzle) of the mounter and balanced. However, it is transported to a predetermined position and mounted on the printed board, preventing parts from falling off and being displaced.

こうしたマウンターにおいて、エアー吸引ノズルの吸着位置は、個々の部品の重心部になるが、部品によっては、吸着部となる重心部に切り欠きのある場合（部品Ｂ）や貫通穴がある場合（部品Ａ）があり、吸着時にマウンターノズルからエアーが漏れて吸い付けることができない部品がある。   In such a mounter, the suction position of the air suction nozzle is the center of gravity of each part. However, depending on the part, the center of gravity that becomes the suction part has a notch (part B) or a through hole (parts). A), and there are parts that cannot be sucked because air leaks from the mounter nozzle during suction.

こうした特定部品を実装するために、マウンターノズルでの部品の吸着を改善する試みがなされている。例えば、特許文献１では、当該部品の重心部（吸着部）に相当する部分に耐熱性テープを貼付けたり（図１１ｂ）、また、特許文献２では、モールドや金属性キャップ等の嵌め込み部材で覆うことが提案されている。   In order to mount such specific parts, attempts have been made to improve the adsorption of the parts at the mounter nozzle. For example, in Patent Document 1, a heat-resistant tape is attached to a portion corresponding to the center of gravity (adsorption portion) of the part (FIG. 11b), and in Patent Document 2, it is covered with a fitting member such as a mold or a metallic cap. It has been proposed.

しかしながら、特許文献１による方法では，自動実装後の部品を低圧雰囲気下に晒して、吸着面を気化させて部品から除去するために、所定の気化温度まで上昇させる必要があり、実装する他の部品への熱損傷が懸念される。また、特許文献２による方法では、モールドや金属性キャップ等の嵌め込み部材を外す必要がある、等それぞれ問題を抱える。   However, in the method according to Patent Document 1, it is necessary to increase the temperature to a predetermined vaporization temperature in order to expose the component after automatic mounting in a low-pressure atmosphere to vaporize the adsorption surface and remove it from the component. There is concern about thermal damage to parts. Further, the method according to Patent Document 2 has problems such as the need to remove fitting members such as molds and metallic caps.

さらに、部品に取り付けられた上記吸着用部材は、リフロー後の外観検査や電気試験での妨げになるため、リフロー後の取り外し工程が必須である（図１１ｃ）。その取り外し工程は、現状、人手作業による方法でしかなく、出荷台数の多い量産品を扱う場合、とくに多大な工数がかかってしまう。
特開平８−１６２７９８号公報 特許３０７９１０２号公報 Furthermore, since the adsorbing member attached to the part becomes an obstacle in appearance inspection and electrical test after reflow, a removal process after reflow is essential (FIG. 11c). At present, the removal process is only a manual method, and particularly when a mass-produced product with a large number of shipments is handled, it takes a lot of man-hours.
JP-A-8-162798 Japanese Patent No. 3079102

そこで、上記問題を解決するため、本発明では、人為的作業による吸着用部材の取り外し作業を軽減する方法として、リフロー熱により吸着用部材を変形させ、かつ、粘着力を低下させることによって、空気抵抗を受けやすい形状や剥がれやすい状態を作り出し、その後、リフロー後の冷却風や、専用の剥がし取り工程を設けることによって、吸着用部材を剥がし取る吸着用部材の除去方法を提供する。   Therefore, in order to solve the above problem, in the present invention, as a method for reducing the work of removing the adsorbing member by human work, the adsorbing member is deformed by reflow heat and the adhesive force is reduced. The present invention provides a method for removing an adsorbing member that peels off an adsorbing member by creating a shape that easily receives resistance and a state in which the adhering member is easily peeled off, and then providing a cooling air after reflow and a dedicated peeling process.

第一の発明は、プリント板の部品実装においてマウンター用に特定部品に取り付けられた吸着用部材の除去方法であって、前記吸着用部材は、シート状のベース部と該ベース部に粘着材が塗布された粘着部とから構成され、リフロー時の加熱によって前記吸着用部材の粘着性を低下させるとともにシート全体を変形させるステップと、リフロー後の冷却工程におけるファンの送風によって前記吸着用部材を前記特定部品から引き剥がすステップと、を有することを特徴とする吸着用部材の除去方法に関する。   A first invention is a method for removing a suction member attached to a specific component for a mounter in component mounting of a printed board, wherein the suction member includes a sheet-like base portion and an adhesive material on the base portion. And a step of reducing the adhesiveness of the adsorbing member by heating during reflow and deforming the entire sheet, and blowing the fan in a cooling step after reflowing. And a step of peeling off from a specific part.

すなわち、第一の発明によれば、部品実装するマウンター用に予め特定部品に取り付けられた吸着用部材を除去する方法であって、シート状のベース部と該ベース部に粘着材が塗布された粘着部とから構成された吸着用部材を、変形手段が、リフロー時の加熱によって吸着用部材の粘着性を低下させるとともにシート全体を変形させ、引き剥がし手段が、リフロー後の冷却工程におけるファンの送風によって吸着用部材を特定部品から引き剥がす構成とすることによって、自動搭載用に特定部品に貼り付けられた吸着用部材をリフロー時の熱により、形状変形、及び粘着機能を低下させて、リフロー後に剥がれやすい状態にし、その後、ファンによる送風によって除去することを可能としている。   That is, according to the first aspect of the present invention, there is provided a method for removing a suction member attached to a specific component in advance for a mounter for mounting a component, in which an adhesive is applied to the sheet-like base portion and the base portion. The adhering member composed of the adhering part is deformed by the deforming means to reduce the adhering property of the adsorbing member by heating at the time of reflow and the entire sheet is deformed, and the peeling means is used for the fan in the cooling process after the reflow. By adopting a configuration in which the suction member is peeled off from the specific part by blowing air, the shape of the suction member attached to the specific part for automatic mounting is reduced by the heat during reflow, and the adhesive function is reduced, and reflow is performed. It is possible to make it easy to peel off later and then remove it by blowing with a fan.

第二の発明は、前記吸着用部材のベース部は２枚のシート部から構成され、前記粘着部側のシート部として熱膨張材料を、他方のシート部として熱収縮材料を適用したことを特徴とする上記第一の発明に記載の吸着用部材の除去方法に関する。   According to a second aspect of the present invention, the base portion of the adsorbing member is composed of two sheet portions, and a thermal expansion material is applied as the sheet portion on the adhesive portion side and a heat shrink material is applied as the other sheet portion. The present invention relates to a method for removing an adsorbing member according to the first invention.

すなわち、第二の発明によれば、吸着用部材のベースとなるシート部を熱収縮または熱膨張と機能の異なる２枚のシート部の組合せで構成することによって、リフロー熱により形状変化させるが可能となる。   That is, according to the second invention, the shape of the sheet portion serving as the base of the adsorbing member can be changed by reflow heat by forming a combination of two sheet portions having different functions from thermal contraction or thermal expansion. It becomes.

第三の発明は、前記吸着用部材のベース部における２枚のシート部材は、前記粘着部側のシート部の厚さを他方より薄く形成させてなることを特徴とする上記第二の発明に記載の吸着用部材の除去方法に関する。   According to a third aspect of the present invention, the two sheet members in the base portion of the adsorption member are formed such that the thickness of the sheet portion on the adhesive portion side is thinner than the other. The present invention relates to a method for removing the adsorbing member.

すなわち、第三の発明によれば、吸着用部材のベース部は、２枚のシート部からなるベース部の一方の厚みを変えた構成とすることによって、より確実に変形させることが可能となる。   That is, according to the third invention, the base portion of the adsorption member can be more reliably deformed by changing the thickness of one of the base portions composed of two sheet portions. .

第四の発明は、前記吸着用部材のベース部における２枚のシート部は、前記粘着部側のシート部に発泡剤を分散させてなることを特徴とする上記第二の発明に記載の吸着用部材の除去方法に関する。   According to a fourth aspect of the present invention, the two sheet portions in the base portion of the adsorption member are formed by dispersing a foaming agent in the sheet portion on the adhesive portion side. The present invention relates to a method for removing a member.

すなわち、第四の発明によれば、粘着部側のシート部に発泡剤を混入させることによって、熱による耐熱材からなるシート部の膨張と同時に、他方の収縮材からなるシート部材の収縮で伸縮作用が大きくなり、より変形が確実となる。   That is, according to the fourth invention, by adding a foaming agent to the sheet portion on the adhesive portion side, expansion and contraction of the sheet member made of the other shrinkage material simultaneously with expansion of the sheet portion made of heat-resistant material due to heat. The action becomes larger and the deformation is more sure.

第五の発明は、前記吸着用部材のベース部は、前記粘着部側に発泡剤を偏らせた単一のシート部で形成させたことを特徴とする上記第一の発明に記載の吸着用部材の除去方法に関する。   According to a fifth aspect of the present invention, the base portion of the adsorption member is formed by a single sheet portion in which a foaming agent is biased toward the adhesive portion side. The present invention relates to a member removal method.

すなわち、第五の発明によれば、吸着用部材のベース部を単一のシート部で形成し、発泡剤を粘着部側に偏らせて構成することによって、２枚のシート部の一方に発泡剤を含ませた場合と同様に、粘着部側に近い領域と他側の領域とで熱処理時の熱膨張率の差を作ることができ、ベース部の変形を確実に生じさせることを可能とする。   That is, according to the fifth invention, the base part of the adsorbing member is formed by a single sheet part, and the foaming agent is biased toward the adhesive part side to form one of the two sheet parts. As in the case of containing an agent, it is possible to create a difference in the coefficient of thermal expansion during heat treatment between the region close to the adhesive portion side and the region on the other side, making it possible to reliably cause deformation of the base portion. To do.

第六の発明は、前記吸着用部材の粘着部は、粘着材の塗布領域を幅方向に変化させて形成させたことを特徴とする上記第一の発明に記載の吸着用部材の除去方法に関する。   A sixth invention relates to the method for removing an adsorbing member according to the first invention, wherein the adhering portion of the adsorbing member is formed by changing the application region of the adhesive material in the width direction. .

すなわち、第六の発明によれば、吸着用部材の粘着部を、粘着領域を長手方向で変える構成とすることによって、粘着領域の狭い方から変形し始め螺旋状にすることが可能となる。   That is, according to the sixth invention, the adhesive portion of the adsorbing member is configured to change the adhesive region in the longitudinal direction, so that it can start to be deformed from the narrow side of the adhesive region and become spiral.

現状のリフロー炉内は、基板を予備加熱するエリアと半田を溶融する本加熱エリアと加熱した基板を冷却するエリアとに分けられる。本発明により、現状のリフロー炉に手を加えることなく、そのまま利用する方法として、リフロー熱による吸着用部材の変形と粘着機能を低下させることで、冷却エリアでの送風等によって、吸着用部材を剥がしとることが可能となる。また、冷却エリアでの取り外しの替わりに、取り外し専用工程をリフロー工程後に設ければ、更に確実な取り外しができる。   The current reflow furnace is divided into an area for preheating the substrate, a main heating area for melting the solder, and an area for cooling the heated substrate. According to the present invention, as a method to use as it is without modifying the current reflow furnace, by reducing the deformation and adhesion function of the adsorbing member due to reflow heat, the adsorbing member is blown in the cooling area or the like. It can be peeled off. Further, if a dedicated removal process is provided after the reflow process instead of the removal in the cooling area, a more reliable removal can be performed.

以上のことから、現行の設備をそのまま活かすことで人為的作業を減らせるため製造コストを下げることができる。   In view of the above, manufacturing costs can be reduced because manpower can be reduced by utilizing the current equipment as it is.

以下、図面にもとづいて本発明の実施形態を説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の実施の形態になるマウンターによる実装時に特定部品に貼り付けた吸着用部材の引き剥がし方法を示す。本発明では、プリント板実装ライン上の部品マウント工程において、吸着用のマウンターノズルによる吸引対応が不可能な部品、例えば、ソケット、コネクタ等、部品の重心に凹部がある特定部品に対し、吸着テープ（吸着用部材）を貼り付けた場合を前提としている。   FIG. 1 shows a method of peeling off a suction member attached to a specific component during mounting by a mounter according to an embodiment of the present invention. In the present invention, in the component mounting process on the printed circuit board mounting line, the suction tape is applied to a component that cannot be suctioned by the suction mounter nozzle, for example, a specific component having a recess at the center of gravity of the component such as a socket or a connector. It is assumed that (adsorption member) is pasted.

図１ａは、プリント板への部品の実装工程を示し、図１ｂは、各工程における吸着テープの状態を示している。部品実装工程は、常温エリア１０１において、マウンター１によってピックアップした各種部品がプリント板の所定位置にセットされ、リフロー炉２を構成する予備加熱エリア２０１、本加熱エリア２０２、および冷却エリア２０３を通過することによって、半田が溶かされ、搭載部品がプリント板３に固定される。   FIG. 1a shows a mounting process of components on a printed board, and FIG. 1b shows a state of the suction tape in each process. In the component mounting process, various components picked up by the mounter 1 are set at predetermined positions on the printed board in the room temperature area 101, and pass through the preheating area 201, the main heating area 202, and the cooling area 203 constituting the reflow furnace 2. As a result, the solder is melted and the mounted component is fixed to the printed board 3.

また、常温エリア１０１において、マウンターノズル（図示していない）によって重心位置に凹部のある特定部品１０ａ（吸着部となる重心部に貫通穴がある部品）、１０ｂ（吸着部となる重心部に切り欠きのある部品）が確実にピックアップされるように、エアー漏れを防止するための吸着テープ１１が予め特定部品１０ａ、１０ｂに貼り付けられている。   In the normal temperature area 101, a specific part 10a having a recess at the center of gravity position (a part having a through hole in the center of gravity serving as the suction part) and 10b (cutting into the center of gravity serving as the suction part) by a mounter nozzle (not shown). Adsorption tape 11 for preventing air leakage is affixed to specific parts 10a and 10b in advance so as to reliably pick up the chipped parts.

つぎに、部品実装されたプリント板３が、予備加熱エリア２０１に入ると、周囲温度上昇に伴い、吸着テープ１１は変形し始め、粘着機能が低下してくる。   Next, when the printed circuit board 3 on which components are mounted enters the preheating area 201, the suction tape 11 starts to be deformed as the ambient temperature rises, and the adhesive function is lowered.

さらに、本加熱エリア２０２において、周囲温度がＭａｘになった時点で、吸着テープ１１は大きく変形し、引き剥がしが可能な状態となる。   Further, in the main heating area 202, when the ambient temperature reaches Max, the suction tape 11 is greatly deformed and can be peeled off.

つまり、特定部品１０ａ、１０ｂに貼り付けた吸着テープ１１は、マウント工程時の常温環境下では貼り付け状態を維持し、その後のリフロー工程内の高温環境下で変形させ、粘着機能を低下させることができる。   That is, the adhesive tape 11 attached to the specific parts 10a and 10b is maintained in the attached state in a normal temperature environment during the mounting process, and is deformed in a high temperature environment in the subsequent reflow process to reduce the adhesive function. Can do.

以下、図２〜図７を用い、本発明の主要素であるリフロー工程で変形させて自動的な引き剥がしを行うのに好適な吸着テープ１１の構成例について説明する。   Hereinafter, a configuration example of the suction tape 11 suitable for performing automatic peeling by being deformed in the reflow process which is the main element of the present invention will be described with reference to FIGS.

図２は、本発明の実施の形態になる吸着用部材の構成例（その１：ベース部を材質の違う２層で構成）を示す。本実施例は、吸着テープ１１が、熱収縮材からなるシート１２ａおよび耐熱材からなるシート１２ｂとを張り合わせた２層構成のベース部１２と粘着部１３とから構成された場合を示している。つまり、ベース部１２は、熱膨張率の異なる２つの材料の組合せによって構成されている。   FIG. 2 shows an example of the structure of the adsorbing member according to the embodiment of the present invention (part 1: the base is composed of two layers of different materials). In this embodiment, the adsorbing tape 11 is composed of a base portion 12 and an adhesive portion 13 having a two-layer structure in which a sheet 12a made of a heat-shrink material and a sheet 12b made of a heat-resistant material are bonded together. That is, the base part 12 is comprised by the combination of two materials from which a thermal expansion coefficient differs.

シート１２ｂは、リフロー温度、約２４０℃に対し、溶融や気化・燃焼等を生じない耐熱性のある材料で形成する。例えば、耐熱材としてポリイミド系樹脂等が好適である。一方、シート１２ａの収縮材としては、ポリオレフィン系やフッ素系熱収縮樹脂等が好適である。このように、ベース部１２のシート１２ａには収縮材、シート１２ｂには耐熱材の組合せで形成することによって吸着テープ１１の熱変形が可能となる。   The sheet 12b is formed of a heat-resistant material that does not cause melting, vaporization, combustion, or the like with respect to a reflow temperature of about 240 ° C. For example, a polyimide resin or the like is suitable as the heat resistant material. On the other hand, as the shrink material of the sheet 12a, polyolefin-based or fluorine-based heat-shrinkable resin is suitable. As described above, the adhesive tape 11 can be thermally deformed by forming the sheet 12a of the base portion 12 with a combination of a shrink material and the sheet 12b with a heat-resistant material.

また、粘着部１３は、ベース部１２裏面に塗布されており、粘着機能が高温によって低下する粘着材を適用することによって、吸着テープ１１を熱変形させ、剥がし取れる状態にすることができる。   Moreover, the adhesion part 13 is apply | coated to the back surface of the base part 12, and the adhesive tape 11 can be thermally deformed and made into the state which can be peeled off by applying the adhesive material to which an adhesion function falls by high temperature.

図３は、本発明の実施の形態になる吸着用部材の構成例−その２（ベース部の２層間の厚みを変えた構成）を示す。本実施例は、ベース部１２が熱膨張率の異なる２層で構成された図２の場合について、さらに、確実に熱変形を起こさせる例である。   FIG. 3 shows a structural example of the adsorbing member according to the embodiment of the present invention-part 2 (a structure in which the thickness between the two layers of the base portion is changed). The present embodiment is an example in which the thermal deformation is further reliably caused in the case of FIG. 2 in which the base portion 12 is configured of two layers having different thermal expansion coefficients.

２層で構成するベース部１２の内、シート１２ｂの厚みを薄くする（シート１２ｂの厚さＴ２＜シート１２ａの厚さＴ１) ことによって、シート１２ａの熱による収縮力を増増加させ、より確実に変形させることが可能となる。   By reducing the thickness of the sheet 12b in the base portion 12 composed of two layers (thickness T2 of the sheet 12b <thickness T1 of the sheet 12a), the contraction force due to heat of the sheet 12a is increased and more reliably. It is possible to deform it.

図４は、本発明の実施の形態になる吸着用部材の構成例−その3 （ベース部の１層に発泡剤を含ませた場合）を示す。本実施例は、ベース部１２が熱膨張率の異なる２層で構成された図２の場合について、さらに、確実に熱変形を起こさせる別な例である。   FIG. 4 shows a configuration example of the adsorbing member according to the embodiment of the present invention-part 3 (when a foaming agent is included in one layer of the base portion). The present embodiment is another example in which thermal deformation is further reliably caused in the case of FIG. 2 in which the base portion 12 is composed of two layers having different thermal expansion coefficients.

シート１２ｂ側を発泡剤を混入させた層で構成することによって、熱によりシート１２ｂが膨張すると同時に、シート１２ａでは収縮が生じ、伸縮作用が大きくなって、より変形が確実となる。   By configuring the sheet 12b side with a layer in which a foaming agent is mixed, the sheet 12b expands due to heat, and at the same time, the sheet 12a contracts, the expansion / contraction action increases, and the deformation becomes more reliable.

図５は、本発明の実施の形態になる吸着用部材の構成例−その4 （ベース部を発泡剤を含む単一層で形成）を示す。本実施例は、発泡剤を使った場合の別のシート構成（単一層）を示している。   FIG. 5 shows a structural example of an adsorbing member according to an embodiment of the present invention-part 4 (the base portion is formed of a single layer containing a foaming agent). This example shows another sheet configuration (single layer) when a foaming agent is used.

図に示すように、単一のシート層として、ベース部１２の下方（粘着部１３側）に、発泡剤を偏らせて形成する。同一の樹脂内で、発泡剤の多い領域と少ない領域を形成することによって、熱により上方と下方で膨張差が生じ、上述してきた２層シート構成による熱変形と同じ作用をさせることが可能となる。   As shown in the figure, as a single sheet layer, a foaming agent is biased and formed below the base portion 12 (on the adhesive portion 13 side). By forming a region with a large amount of foaming agent and a region with a small amount in the same resin, a difference in expansion occurs between the upper side and the lower side due to heat, and it is possible to have the same effect as the thermal deformation by the two-layer sheet configuration described above. Become.

図６は、本発明の実施の形態になる吸着用部材の構成例−その５（粘着部領域を変化）を示す。本実施例では、粘着部の領域を変化させることによって吸着テープを変形させる方法について示している。   FIG. 6 shows a structural example of an adsorbing member according to an embodiment of the present invention-part 5 (changes the adhesive area). In this embodiment, a method for deforming the suction tape by changing the region of the adhesive portion is shown.

図に示すように、粘着部１３（ハッチ部分）の幅を段階的に変化させた構成とすることによって、吸着テープ１１は、加熱時に幅方向に粘着力の差を生じ、長手方向に変形が起き、粘着領域の狭い方から変形し始め、螺旋状にカールしていく。   As shown in the figure, by adopting a configuration in which the width of the adhesive portion 13 (hatch portion) is changed stepwise, the suction tape 11 causes a difference in adhesive force in the width direction during heating and is deformed in the longitudinal direction. Wake up and begin to deform from the narrow side of the adhesive area and curl spirally.

図７は、本発明の実施の形態になる吸着用部材の構成例- その５（粘着部領域を変化）を示す。これまでは、熱によって粘着機能がなくなる粘着材を使用することを前提とした変形方法について述べてきたが、本実施例では、粘着部に通常の熱可塑性タイプの材料を適用する場合に好適なシート構成を示す。   FIG. 7 shows a structural example of an adsorbing member according to an embodiment of the present invention-part 5 (changes the adhesive part region). So far, the deformation method has been described on the assumption that an adhesive material that loses its adhesive function due to heat has been used, but in this embodiment, it is suitable for the case where a normal thermoplastic type material is applied to the adhesive portion. The sheet configuration is shown.

先ず、収縮材からなるシート１２ａの層と粘着部１３を両サイドに分離し、中央の耐熱材からなるシート１２ｂによる露出部は、マウンター１の吸着ノズルが入るスペースを設けるようにする。この際、粘着部１３の長さは、収縮材からなるシート１２ａの長さより短く，該シートの内側に位置するように形成する。また、粘着部１３は、収縮材が変形する温度より低い温度で溶融する材料を選定する。さらに、変形する領域と変形しない領域の重量配分を「変形なし領域の重量＞変形あり領域の重量」になるように設定する。   First, the layer of the sheet 12a made of the shrink material and the adhesive portion 13 are separated on both sides, and the exposed portion by the sheet 12b made of the central heat-resistant material is provided with a space for the suction nozzle of the mounter 1 to enter. At this time, the length of the adhesive portion 13 is shorter than the length of the sheet 12a made of the shrink material, and is formed so as to be positioned inside the sheet. In addition, the adhesive portion 13 selects a material that melts at a temperature lower than the temperature at which the shrinkable material is deformed. Furthermore, the weight distribution between the deformed area and the undeformed area is set so that “weight of the undeformed area> weight of the deformed area”.

この構成により、熱を上げるに伴って、先ず粘着部１３が軟化し接着力がなくなってくる。接着力がなくなった状態の後、収縮材の部分（シート１２ａ）が変形し、収縮材より短い粘着部１３は、部品との接触面から完全に分離することができる。   With this configuration, as the heat is increased, the adhesive portion 13 is first softened and the adhesive force is lost. After the state where the adhesive force is lost, the shrinkable material portion (sheet 12a) is deformed, and the adhesive portion 13 shorter than the shrinkable material can be completely separated from the contact surface with the component.

また、中央の耐熱材部分は、熱による変形が少ない材料であり、両サイドの変形に動じない重みがあるため、周囲温度Ｍａｘ時でも平な状態を維持しつつ、両サイドの変形する部分を持上げるような形にさせることができる。これにより、吸着テープ１１は、取り外し可能な状態となる。   In addition, the central heat-resistant material is a material that is hardly deformed by heat and has a weight that does not affect the deformation of both sides, so that the parts that deform on both sides are maintained while maintaining a flat state even at the ambient temperature Max. It can be shaped like lifting. Thereby, the adsorption tape 11 will be in a removable state.

図８は、本発明の実施の形態になる変形及び送風による吸着用部材引き剥がしの原理図を示す。これまでに述べてきた吸着テープ１１の構成を用いることによって、リフロー炉の加熱工程で螺旋状やＵ字形状といった空気抵抗の大きな形状に変形を受けた吸着テープ１１は、ファン５の送風によって簡単に特定部品１０ａ、１０ｂから分離することが可能となる。   FIG. 8 shows a principle diagram of deformation and peeling of the adsorbing member by blowing according to the embodiment of the present invention. By using the structure of the suction tape 11 described so far, the suction tape 11 that has been deformed into a shape having a large air resistance such as a spiral shape or a U-shape in the heating process of the reflow furnace can be easily obtained by blowing air from the fan 5. It becomes possible to separate from the specific parts 10a and 10b.

図９は、本発明の実施の形態になるリフロー炉の冷却エリア利用による吸着用部材の除去例を示す。本実施例は、プリント板への部品実装における一連の工程を利用して、吸着用部材の除去を行う例を示している。リフロー後の冷却エリア２０３において、図に示すようなファン（冷却ファン）５から風を吹き付けることによって、変形した吸着用部材１１を自動で剥がしとることができる。   FIG. 9 shows an example of removing the adsorbing member by using the cooling area of the reflow furnace according to the embodiment of the present invention. The present embodiment shows an example in which the suction member is removed using a series of steps in component mounting on a printed board. In the cooling area 203 after reflow, the deformed adsorption member 11 can be automatically peeled off by blowing air from a fan (cooling fan) 5 as shown in the figure.

図１０は、本発明の実施の形態になるリフロー後の専用工程設置による吸着用部材の除去例を示す。本実施例は、別の取外し方法として、リフロー工程後に専用の吸引工程を設ける例を示している。   FIG. 10 shows an example of removing the adsorbing member by installing a dedicated process after reflow according to the embodiment of the present invention. This embodiment shows an example in which a dedicated suction step is provided after the reflow step as another removal method.

プリント板部品実装は、半田印刷工程３０１、部品マウント工程３０２、リフロー工程３０３、吸着用部材吸引工程３０４、および外観検査工程３０５からなる一連の工程で構成されている。本発明では、専用の追加工程として吸着用部材吸引工程３０４を設け、図に示すような吸引ダクト３０を設置し、エリア内に強い空気の流れを起こすことによって、リフロー後に変形した吸着用部材１１の引き剥がしをより確実にさせるものとなる。   The printed board component mounting is composed of a series of steps including a solder printing step 301, a component mounting step 302, a reflow step 303, a suction member suction step 304, and an appearance inspection step 305. In the present invention, the suction member suction process 304 is provided as a dedicated additional process, the suction duct 30 as shown in the figure is installed, and a strong air flow is generated in the area, whereby the suction member 11 deformed after the reflow. This will make it possible to more reliably peel off.
