Abstract
【解決手段】電子部品実装構造体1は、電子部品3と基板2との間に面配置された複数の半田ボール4を溶融させて電子部品3と基板2を接合させるとともに、電子部品3と基板2との隙間であって電子部品3の少なくとも四隅にあたる箇所に硬化後の引張伸びが5%〜40%である樹脂5を充填して補強している。補強面積が小さいので樹脂5の除去容易性、基板再利用性等のリペア性に優れるとともに、落下時の衝撃に対して樹脂5自体の伸びが許容され、破断することなく接合補強の役割を果たすことができ、耐衝撃性にも優れる。
【選択図】図1
Description
ポキシ樹脂と可撓性樹脂を含む樹脂接着剤もしくは可撓性樹脂から成る樹脂接着剤であり、前記電子部品の少なくとも四隅にあたる箇所に充填されるとともに硬化後の引張伸びが5%〜40%である。
た樹脂5の硬化後の引張伸びが5%〜40%の範囲内になるように各樹脂の配合比率が調整される。なお、可塑性樹脂をそのまま接合補強用の樹脂5として用いてもよい。
る。その結果として、衝突により生じた基板2の撓みによる電子部品との隙間の伸び率が硬化後の樹脂5の引張伸びを超えてしまい、樹脂5に亀裂が生じて最終的には破断にまで至る。破断した樹脂5は、当初の目的である接合補強の役割を果たすことができなくなるので、その後の振動のピークで許容応力を超える過大な応力が半田ボール4に発生し、半田が破断することになる。
ボールの破断を防止していることがわかる。従って、樹脂E、F、Gを電子部品の四隅にあたる箇所に充填すると、耐衝撃性に優れるとともにリペア性にも優れた電子部品実装構造体を実現することができる。
