ABSTRACT:
A wire bonder for bonding an insulated wire to a surface is disclosed. The bonder includes a bond head, having a bonding position adjacent to said surface and a wire preparation position spaced apart from the surface. There is a wire holder on the bond head, the wire holder being sized and shaped to permit a free end of the insulated wire to extend from the wire holder when the bond head is in the spaced apart position. A source of insulated wire for said bond head is provided as well as an electrical discharge wand positioned adjacent to said bond head when the bond head is in the spaced apart position. The wand directs sufficient electricity at the extending free end of the insulated wire to form a bond ball on the free end. A ground associated with the insulated wire, is provided the ground being sized and positioned to conduct electrical energy away from the insulated bond wire to prevent the insulation on the bond wire remote from the free end from being damaged.
