lectronics circuitry and base substrate, which are soldered together to build a module. The electronics circuitry (components in figure) includes gate drive, control and protection components. A hybrid (thick film) drive circuitry with high density interconnect is employed to shrink the module size.
Base substrate
The base substrate provides electrical interconnection and thermal path of power chips. An Al2O3 or AlN direct bonded copper (DBC) substrate with 25mil ceramic and 10mil thick copper is used as the base substrate. It is bonded to a 3mm thick heat spreader to improve thermal managem..................[:=> Show Contents <=:]
