20200388589 · 2020-12-10 ·

A method of determining a bonding status between a wire and at least one bonding location of a workpiece is provided. The method includes the steps of: (a) bonding a portion of a wire to a bonding location of a workpiece using a bonding tool of a wire bonding machine; (b) determining a motion profile of the bonding tool for determining if the portion of the wire is bonded to the bonding location, the motion profile being configured to result in the wire being broken during the motion profile if the portion of the wire is not bonded to the bonding location; and (c) moving the bonding tool along the motion profile to determine if the portion of the wire is bonded to the bonding location. Other methods of determining a bonding status between a wire and at least one bonding location of a workpiece are also provided.
