The Westbond 7476D Wedge-Wedge Wire Bonder is a conventional wire bonder that can provide precise control for accurate loop formations.  The convertible wire clamp assemblies allow for a variety of bonding methods: angled-feed or vertical-feed.  The system uses ultrasonic energy to attach aluminum wires at room temperature and workpiece heat for gold wires.
