In power electronics high-performance power modules such as IGBTs (Insulated-Gate Bipolar Transistors) and IPMs (Intelligent Power Modules) are being manufactured increasingly frequently through the use of ultrasonic welding. In contrast to conventional soldering, the ultrasonic welding of the load-current and control connections offers comprehensive monitoring of the process and of quality. In reliability tests ultrasonically-welded power modules achieve approximately a tenfold longer service life. The substance-to-substance bond results in significantly reduced power loss at the points of contact, thus increasing the degree of electrical efficiency and minimizing the need for cooling.
