図1に、樹脂組成物の注入性の評価方法を説明する模式図を示す。まず、図1(A)に示すように、基板20上に50μmのギャップ40を設けて、半導体素子の代わりにガラス板30を固定した試験片を作製した。但し、基板20としては、FR4基板を使用した。次に、この試験片を50℃に設定したホットプレート上に置き、図1(B)に示すように、ガラス板30の一端側に、作製した樹脂組成物10を塗布し、図1(C)に示すように、ギャップ40が樹脂組成物11で満たされるまでの時間を測定した。注入時間の適性範囲は、1000秒以内である。表1~表4に、注入性の評価結果を示す。
樹脂組成物の注入性の評価した試験片をオーブンへ入れ、120℃で3分間加熱し、エポキシ樹脂組成物を硬化させた。加熱後の硬化物外観を目視観察した。硬化物にしわ・柚子肌等の外観不良や色むらが認められなかった場合を○とし、硬化物にしわ・柚子肌等の外観不良や色むらが認められた場合を×とした。表1~表4に、硬化物外観の評価結果を示す。
ガラスエポキシ基板に評価用試料を印刷し、該試料上に2mm×2mmのシリコンチップを載置した。これを、80±2℃の熱風乾燥機で90分間加熱硬化、または100±2℃の熱風乾燥機で90分間加熱硬化させた。これを試験片とし、dage社製万能型ボンドテスター(型番:DAGE4000)を用いてシリコンチップに荷重をかけ、チップが剥離した時の強度(剥離強度)を測定した。n=10とし、その平均値を強度とした。なお、100N未満の場合は、未硬化とした。表1~表4に、強度の評価結果を示す。
