    摘要: 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.

    摘要: A bonding apparatus includes: a clamper able to clamp a wire between a pair of arms; a horn, in which a first through hole able to hold a capillary, and a second through hole adjacent to the first through hole and penetrating the horn in an up-down direction are further formed; and a bonding stage able to carry a workpiece. An alignment method for aligning a horn and a damper of a bonding apparatus with each other includes: disposing a mirror surface to be parallel to a bonding stage; aligning a mirror image of a second through hole reflected on the mirror surface with a center of the second through hole when the mirror surface is viewed through the second through hole; and aligning the damper based on a position of the mirror image and the horn.
