Abstract:
An integrated power electronic module including:a first substrate, a second substrate, power semiconductor devices attached and electrically connected to said second substrate with ball bonds, said ball bonds having an hour glass configuration formed from a ball and inner and outer solder layers connected to pads on said second substrate and said power semiconductor device, respectively, underfill having a glass transition temperature above a service temperature of said power semiconductor device located adjacent said ball bonds and between a base of said power semiconductor device and said second substrate, said first substrate with said second substrate and said power semiconductor devices being connected together in a configuration where said power semiconductor devices are sandwiched between said first substrate and said second substrate, encapsulant positioned between power semiconductor devices and said first and second substrates, and means for removing heat from said power semiconductor devices associated with at least one of said first and second substrates.
