The reliability of classical power modules with various solder interfaces is not sufficient to meet the demand of progressive applications in power electronics. Technologies were developed in the last decade to improve the reliability. The elimination of the base plate prevents the solder fatigue failure in the substrate solder layer and permits the implementation of arbitrary ceramic materials. Spring contacts and pressure contacts replace soldered terminals. Diffusion sintering substitutes the chip solder layer. The combination of these technologies leads to a module architecture without any solder layer that has the potential to exceed the reliability limits of classic modules.
