Patent ID: 7658314

Claim:
A tail wire cutting method for a bonding apparatus cutting a tail wire paid out at a tip end of a capillary, after bonding a wire from a first bonding point to a second bonding point comprising the steps of: opening a clamper of said bonding apparatus and raising said capillary together with said clamper from said second bonding point to a first height to pay out said tail wire at said tip end of said capillary; then closing said clamper and causing said capillary together with said clamper to make one of arc-shaped reciprocating oscillation movement and circular oscillation movement on a curved surface having an apex thereof at said first height, thus degrading a rigidity of a connecting portion between said tail wire and said second bonding point; then opening said clamper and raising said capillary together with said clamper from said first height to a second height to pay out further said tail wire at said tip end of said capillary; and then closing said clamper and raising further said capillary together with said clamper from said second height to cut said tail wire from said second bonding point.
