Description
前記第1ボンディング工程は、後記するワイヤ切断工程によって形成されるテール部を第1ボンド点にボンディングして下部第1ボンディング部を形成する工程と、キャピラリを上昇及び前記下部第1ボンディング部の上方に移動させ、その後キャピラリを下降させてワイヤを前記下部第1ボンディング部上に重ねて接続して中間第1ボンディング部を形成する工程と、再度キャピラリを上昇及び前記中間第1ボンディング部の上方に移動させ、その後キャピラリを下降させてワイヤを前記中間第1ボンディング部上に重ねて接続して上部第1ボンディング部を形成する工程とからなり、
前記第2ボンディング工程は、ワイヤを第2ボンド点にボンディングして下部第2ボンディング部を形成する工程と、キャピラリを上昇及び前記下部第2ボンディング部の上方に移動させ、その後キャピラリを下降させてワイヤを前記下部第2ボンディング部上に重ねて接続して上部第2ボンディング部を形成する工程とからなり、この第2ボンディング工程後にキャピラリを僅かに上昇させ、続いてクランパが閉じてクランパ及びキャピラリを共に横方向に移動させてワイヤを切断するワイヤ切断工程を行い、キャピラリの先端部より僅かに突出した長さのテール部を形成することを特徴とする。
第2ボンディング工程は、ワイヤを第2ボンド点にボンディングして下部第2ボンディング部を形成し、この下部第2ボンディング部上に再度ワイヤを重ねて接続して上部第1ボンディング部を形成するので、第2ボンド点においてもボンディングの接合性が向上する。
また、ワイヤ切断後に形成されるテール部は、第2ボンディング工程後にキャピラリを僅かに上昇させ、続いてクランパが閉じてクランパ及びキャピラリを共に横方向に移動させてワイヤを切断するワイヤ切断工程を行い、キャピラリの先端部より僅かに突出した長さに形成するので、特別な装置を用いなくてもボールレスボンディングができる。
