Description
図示によって説明すると、キャピラリによるウェッジ接合では、図1に示すように、ボンディングワイヤ(1)がリード(3)にウェッジ接合される。この際、ウェッジ接合されたボンディングワイヤ(1)の端部はキャピラリ(2)の先端部によって押し潰され、図2に示すように、接合箇所のワイヤの面積が最も小さくなる。さらに、その後ボンディングワイヤ(1)が切り離される。これは、キャピラリ(2)の上部にあるワイヤクランパ(4)によってボンディングワイヤ(1)を掴んで上方に引き上げると、図3に示すように、残ボンディングワイヤ(1)の先端部分でワイヤが簡単に切れるようになっている。
テールワイヤの折曲り試験は、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、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、いずれも本発明の範囲外の銅合金ワイヤよりも高い値を示した。
