Power Modules is a rapidly growing segment with high-growth applications ranging from electric vehicles, high-speed rail, and a variety of industrial applications. However, the stack of interconnects in power modules is the source of mechanical failures. Removal of heat between the DBC and baseplate is often the main source of thermal mismatches, making voids in this joint the most pressing challenge for power module manufacturers.

SST Vacuum Reflow Systems' Alex Voronel takes viewers through the challenges facing the IGBT Power Module device manufacturers with typical failure modes and how to solve them using a flux-less soldering process resulting in very low voiding using a reliable Formic Acid or Forming Gas option.
