Description
図4AははんだS1が溶融する前の状態を示している。図4Bは、はんだS1が溶融しリード20が本体10に対して下方に移動した状態を示している。はんだS1が溶融すると、毛細管現象によりはんだS1がリード20上を伝わろうとする。また、リード20が本体10に対して下方に移動した場合は、はんだS1は上端22にまで伝わりやすくなる。しかしながら、リード20には第1傾斜部25が形成されている。これにより、本体10に対してリード20が下方に移動した場合であっても、はんだS1が第2傾斜部26から第1傾斜部25へとつたわるのを防止できる。
図7A、7B、8A、8Bははんだの濡れ角の説明図である。図7A、7Bは、凸部24を有しているリード20におけるはんだの濡れ角の説明図である。溶融したはんだS1が毛細管現象及びリード20の移動により、図7Aに示すように、第2傾斜部26から第1傾斜部25へとつたわる場合を想定する。この場合には、第2傾斜部26上にあるはんだS1の濡れ角と第1傾斜部25の濡れ角の間の角度θ1は、比較的大きな角度になる。
図10に示すように、第2傾斜部26においては、Ni層23bが部分的に露出している。第1傾斜部25には、Au層23cは存在しておらず、Ni層23bが露出している。このような場合であっても、第2傾斜部26側のNi層23bには部分的にAu層23cが覆っているので、第1傾斜部25は、第2傾斜部26よりもはんだ濡れ性が低い。このため、第2傾斜部26から第1傾斜部25へ溶融したはんだがつたわることが防止される。
図11は、半導体チップを備えた電子部品の説明図である。チップパッケージ1aは、本体10a、リード20とを含む。本体10aは、封止樹脂11a、導電パッド12、半導体チップ41、リードフレーム44を含む。半導体チップ41、リードフレーム44は封止樹脂11aにより封止されている。封止樹脂11aの側面には導電パッド12が固定されている、半導体チップ41と導電パッド12とはボンディングワイヤ46により電気的に接続されている。導電パッド12とリード20とははんだS1により接合されている。即ち、はんだS1が溶融するとリード20は本体10aに対して移動可能となる。リード20にははんだS1を挟むように凸部24が設けられている。このように、コネクタのみならず、半導体チップを備えた電子部品のリードに上記リードを採用した場合にも、はんだがリード20をいきわたることを防止できる。
