Abstract
【解決手段】Cuを2重量%以下、Ni0.002重量%以上0.2重量%以下、Ga0.001重量%以上1重量%未満、残部Snからなことを特徴とする無鉛はんだ合金である。Gaを添加することにより、はんだ合金に良好な伸びが付与される。はんだの伸びは、粘りとなってストレスを吸収し、安定したはんだ接合部を形成する。
【選択図】図6
Description
Cu0.3重量%、Ni0.05重量%、Ga0.1重量%、残部Snから成る実施例1のはんだ合金と、Cu0.3重量%、Ni0.05重量%、残部Snから成る比較例Aのはんだ合金のそれぞれに対して引張試験を行い、その引張力(強度)と合金の伸びを測定したところ、表1の結果が得られた。尚、試験を行うために必要となった引張力は合金自体の硬さとして評価する。
Cu0.3重量%、Ni0.1重量%、Ga0.1重量%、残部Snから成る実施例2のはんだ合金と、Cu0.3重量%、Ni0.1重量%、残部Snから成る比較例Bのはんだ合金のそれぞれに対して試験1と同様の引張試験を行ったところ、表2の結果が得られた。
Cu0.7重量%、Ni0.05重量%、Ga0.01重量%、残部Snから成る実施例3のはんだ合金と、Cu0.7重量%、Ni0.05重量%、Ga0.1重量%、残部Snから成る実施例4のはんだ合金と、Cu0.7重量%、Ni0.05重量%、残部Snから成る比較例Cのはんだ合金のそれぞれに対して上記各試験と同様の引張試験を行ったところ、表3の結果が得られた。
Cu0.5重量%、Ni0.05重量%、Ga1重量%、残部Snから成る参考例のはんだ合金と、Cu0.5重量%、Ni0.05重量%、残部Snから成る比較例Dのはんだ合金のそれぞれに対して上記各試験と同様の引張試験を行ったところ、表4の結果が得られた。
Cu0.7重量%、Ni0.05重量%、残部Snから成る組成のはんだ合金0.3gを銅板或いはニッケル板の上に置き、ロジン系フラックスを用いて240℃で2分間ホットプレート上ではんだ付けした。図5(a)は、上記はんだ合金を銅板にはんだ付けした接合界面の拡大写真であり、同図(b)はニッケル板にはんだ付けした接合界面の拡大写真である。このはんだ合金は銅板に対してはニッケルバリアが作用しており、銅板からの銅の溶出が抑制されている(図5(a))。従って、銅板に対しては十分な接合強度が得られていると言える。しかし、ニッケル板に対してはバリア効果が作用しておらず、ニッケル板からニッケルが溶出している(図5(b))。そのため、ニッケル板との接合界面は脆く、ヒートサイクル時に界面剥離を生じる虞がある。
