Abstract
Abstract An electronics case, a method of manufacturing the same and a power module incorporating the case. In one embodiment, the case includes: (1) an enclosure including a metal substrate that forms walls of the enclosure and a dielectric material located on inner surfaces of the walls that insulate the substrate from electronics components located within the enclosure and (2) an electrically conductive pin, affixed to a sidewall of the enclosure substrate and extending to without the enclosure, that allows the substrate to be electrically coupled to a structure supporting the case for EMI (electromagnetic interference) shielding or case-grounding purposes.
