Abstract
Ultrasonic wire bonding using a complex vibration tip is proposed and studied. The complex vibration welding tips designed consist of a transverse vibration rod vibrating in a perpendicular direction, and driven by (1) different (40 kHz and 60 kHz) or (2) the same vibration frequency (60 kHz) longitudinal vibration systems. Welding tip vibration locus and direction are controlled by regulating these vibration systems. Thin aluminum wire and copper plate specimens are welded successfully by these equipments. The weld strength also is independent of the direction of wire length with this method.Keywords
