Abstract
The trend of using silicon carbide power modules is driven by applications in traction, electric vehicles, and renewable energy generation. However, higher power density and temperature pose more severe challenges to the reliability of wire bonds in the package. This paper investigates the effects of geometric parameters on wire bond reliability through a comparison of single and double bonds and finds that double bonding can significantly enhance the thermal-mechanical performance of bonding wire.
