Power semiconductor module with a bowl-shaped support base

摘要

The module has an electrical insulating substrate (5) arranged within a housing (3). The substrate consists of an insulating material body and electrically insulated metallic connection paths. A power semiconductor unit (72) is provided with a connecting unit. A base plate (2) has a tub-shaped part that encloses the substrate such that the side walls of the base plate exhibits larger height than the height level of a casting mass (80) inside the base plate, where the casting mass is silicon rubber and the plate is fixed to the substrate by an adhesive joint.
