IGBT/SiC Terminal Ultrasonic Welding System

The IGBT/SiC Terminal Ultrasonic Welding System was developed specifically for terminal bonding of power semiconductor modules and is suitable for highly reliable contacting of IGBT and SiC power modules. The system combines a fully servo-driven motion system with optical positioning and process guidance technology, enabling highly precise automatic positioning and reproducible welding processes. Manual, semi-automatic, and fully automatic loading concepts are supported — from prototype manufacturing to series production. The system processes terminal areas from 2 to 25 mm² with material thicknesses of 0.3 to 1.5 mm. All process data are traceable; MES system integration is possible as standard. An extraction and filter system for cleanroom applications is optionally available.
