Description
ボンディングワイヤの屈曲試験は、以下のようにして行った。すなわち、ワイヤボンダー(新川社製 UTC−3000)を用い、25℃の周囲温度の銀(Ag)めっき銅(Cu)板に超音波出力 100mA、ボンド荷重90gfの条件で100本ウェッジ接合をした。そして、このウェッジ接合の終了後、図1に示すように、キャピラリ(2)を上昇させてキャピラリ(2)の先端にボンディングワイヤ(1)を繰り出し、その後ワイヤクランパ(4)を閉にした後、キャピラリ(2)とワイヤクランパ(4)とを一緒に上昇させることにより、図3に示すように、キャピラリ(2)の先端に所定の長さのボンディングワイヤ(1)を延出させた状態でワイヤを切断した。これを千回行い、拡大投影機にてボンディングワイヤの屈曲本数を調べた。この測定結果を表1右欄に示す。なお、ヤング率も測定したが、いずれも高い値を示した。
