Abstract:
A wire bonding method in which a first bonding point and a second bonding point are connected by a wire that passes through a capillary, comprising the steps of:connecting a tip end of the wire to a first bonding point, raising a capillary to deliver the wire, performing a first reverse operation in which the capillary is moved in a direction opposite from the second bonding point, raising the capillary to deliver the wire, moving the capillary toward the second bonding point to form a first kink in said wire, then lowering the capillary a predetermined amount to make a stronger first kink, raising the capillary to deliver the wire, performing a second reverse operation in which the capillary is caused to move in an opposite direction from the second bonding point, raising the capillary to deliver the wire, then moving the capillary toward the second bonding point to form a second kink in said wire, raising the capillary to deliver the wire, and connecting the wire to the second bonding point.
