Abstract
【解決手段】加熱可能な金属製のヘッド本体5にエラストマーからなる弾性圧着部材7を有する熱圧着ヘッド3を用いて配線基板10上に電気部品20を実装する方法であって、配線基板10上の実装領域に接着剤を配置した後、電気部品20を実装領域に配置し、熱圧着ヘッド3を用いて電気部品20を配線基板10上に熱圧着する工程を有する。熱圧着の際、電気部品20の頂部領域21をヘッド本体5の金属部分によって押圧する一方、電気部品20の側部領域22近傍の接着剤30を弾性圧着部材7のテーパ部7aによって押圧する。
【選択図】図4
Description
このような電気部品を導電性接着剤等を用いてフリップチップ実装する場合、通常は金属・セラミック等の硬質の圧着ヘッドを用いて熱圧着することが行われている。
このような弾性部材を圧着ヘッドとして用いた場合、高さの異なる複数の電気部品の圧着が可能になるとともに、ICチップの他に抵抗器・コンデンサ等の異なる種類の電子部品を同時に一括に圧着することができるというメリットがある(例えば特許文献1参照)。
一方、上述した弾性体からなる圧着ヘッドを用いた場合には、熱圧着の際に圧着ヘッド側からの加熱が十分でないことから実装に長時間を要するという問題がある。
請求項2記載の発明は、請求項1記載の発明において、前記弾性圧着部材の前記金属押圧部の周囲の部分がテーパ状に形成されており、当該テーパ部によって前記電気部品の側部領域近傍の接着剤を当該側部領域に向って押圧するものである。
また、図2(a)(b)は、同熱圧着ヘッドの押圧面と電気部品の頂部領域の寸法関係を示す説明図である。
これらのうち、異方導電性接着剤は、接続信頼性を向上させる観点から、より好ましいものである。
なお、異方導電性接着剤としては、フィルム状、ペースト状のいずれも使用することができる。
そして、ヘッド本体5の凹部5aの電気部品20に対応する位置(例えば中央部分)には、後述する金属押圧部5bが例えば一体成形によりヘッド本体5と一体的に設けられている。
また、弾性圧着部材7は、金属押圧部5bの周囲において金属押圧部5の押圧面50が凹んだ状態で露出するように装着されている。
この金属押圧部5bは、例えば四角柱状に形成され、その先端部には矩形平面状の押圧面50が形成されている。
すなわち、弾性圧着部材7の開口壁面部分に所定の角度のテーパ部7aを形成し、弾性圧着部材7の押圧面50上の開口部8を電気部品20の頂部領域21の大きさより大きくすることが好ましい。
図3(a)に示すように、まず、本実施の形態では、基台2上に載置された配線基板10の実装領域に接着剤30を配置し、さらにこの接着剤30上の所定の位置に電気部品20を配置する。
そして、図示しない保護フィルムを電気部品20上に配置し、所定の条件で仮圧着(位置決め)を行った後、図3(b)に示すように、ヘッド本体5を下降させ、本圧着として、電気部品20に対して所定時間加熱加圧を行う。
また、図4(b)に示すように、弾性圧着部材7のテーパ部7aの表面によって電気部品20の周囲の接着剤30のフィレット部30fが電気部品20の側部領域22側に向って押圧される。
そして、これにより、図3(c)に示すように、接着剤30のフィレット部30fが十分に押圧された状態で電気部品20が配線基板10上に実装される。
例えば、上述の実施の形態においては、ヘッド本体に金属押圧部を一つ設けて一つの電気部品に対して熱圧着を行うようにしたが、本発明はこれに限られず、ヘッド本体に金属押圧部を複数設け、複数の電気部品を同時に熱圧着することもできる。
さらに、本発明は、ICチップ、コンデンサ等の種々の電気部品に適用することができるものである。
