(4)15〜30%
(a)評価方法
Cu板上にフラックスを塗布し、Cu板上に塗布したフラックス上にはんだボールを搭載し、リフローを行った後、はんだ濡れ広がり径を測定した。リフロー工程は、ピーク温度を250℃に設定したリフロー装置を用いて、35℃から1秒毎に1℃ずつ250℃まで温度を上昇させていき、250℃に達した後、30秒間加熱処理を行った。はんだボールの組成は96.5Sn−3.0Ag−0.5Cu、直径は0.3mmである。
(b)判定基準
○:はんだの広がり径が510μm以上
×:はんだの広がり径が510μm未満
(a)評価方法
Cu板上にフラックスを塗布し、Cu板上に塗布したフラックスを300℃まで加熱し、リフローを行った状態にする。加熱後のフラックス残渣にφ100μmのはんだボールを散布させた。そして、フラックス残渣にはんだボールを散布させたCu板を30°傾け、はんだボールの動きを見た。
(b)判定基準
○:フラックス残渣が無いCuと同等程度にはんだボールが転がる
×:フラックス残渣の粘着性によりはんだボールが転がらない
(a)評価方法
Cu板にフラックスを塗布し、リフローを行った後、フラックス残渣を硬化させる工程の有無でアンダーフィル中のボイドの発生の有無を検証した。リフロー工程は、室温から1秒毎に3℃ずつ、250℃まで温度を上昇させていき、250℃に達した後、30秒間加熱処理を行った。実施例、比較例ともリフロー工程後の硬化工程は行わない。実施例、比較例とも、フラックス塗布位置の両側に高さ25μmのスペーサを置き、このスペーサにガラス板を載せ、Cu板とガラス板の間にアンダーフィルを充填した。アンダーフィルを充填した後、165℃で2時間加熱処理を行った。
(b)判定基準
○:ボイドの発生が見られなかった
×:ボイドの発生が見られた
