Power semiconductor module with at least one positioning means for a substrate

摘要

The module (1) has a housing (20) provided with a recess for a substrate (30). The substrate is designed as a switching substrate (36) i.e. insulated metal substrate, or a base plate. The housing comprises a positioning device (60) in a recess, where the positioning device is provided with a springy section (68) i.e. spring bracket, and a contact element (62). The contact element lies at side surfaces (300) of the substrate in a force-fit manner such that pressure is exerted on the contact element. The positioning device and the housing are made of insulating plastic.
