  • Abstract
    This paper presents the ultrasonic welding technique for the copper terminals of large current, high reliability IGBT modules. Investigated topics are the strength of the bonding inferred from the microstructure, the effect of terminal bonding location on the damage to the insulator layer of module structure, and the reliability of large IGBT modules with the ultrasonic welding comparing with conventional soldering.
