Electrical circuit for use in inverter in electric compressor, has metal substrate, and metal base plate presenting barb that is inserted in perforation, where barb is allowed to come into contact with metal substrate

摘要

The circuit (104) has a metal substrate (202), and a dielectric material layer (206) that is allowed to extend on the metal substrate. A perforation (210) is placed in the dielectric material layer. The perforation is allowed to reach the metal substrate. A metal base plate (212) extends above the dielectric material layer, where the metal base plate presents a barb (214) that is inserted in the perforation, where the barb is allowed to come into contact with the metal substrate. An independent claim is also included for an electric device.
