Abstract:
1. A method of bonding wire between first and second bonding points with a bonding tool, comprising, in the order stated, the steps of: forming a first bond at the first bonding point with the bonding tool; moving the bonding tool to a first position spaced from the first bond by a first distance; moving the bonding tool from the first position towards the first bonding point and applying a pressing force on the first bond with the wire but without forming a second bond of the wire; moving the bonding tool to a second position spaced from the first bond by a second distance; forming a kink in the wire; moving the bonding tool to extend a sufficient length of wire to form a wire loop between the first and second bonding points; and thereafter moving the bonding tool to the second bonding point and forming a second bond.
