Thermally conductive case for electrical components and method of manufacture therefor
First Claim
1. A thermally conductive case for holding electrical components comprising:
- a metal substrate having abase and a plurality of peripheries forming four walls, thereby defining a reservoir in the thermally conductive case;
an electrically insulating material located on a substantial portion of an inner surface of each of said base and said walls; and
electrically conductive traces formed on portions of the electrically insulating material of at least two of said inner surfaces.

Abstract
A power supply and a method of manufacture therefor. The power supply includes a circuit board containing conductors for interconnecting electrical components of the power supply and a thermally-conductive case having an integral electrically insulating layer. The thermally-conductive case forms a reservoir to receive the circuit board therein. The power supply further includes a power semiconductor device having a body connected in thermal communication with the thermally-conductive case and terminals coupled to the conductors of the circuit board. The power supply still further includes an encapsulant, located within the reservoir, capable of ensconcing the power semiconductor device and the electrical components. Additionally, electrical leads extend from the power supply that allows the power supply to be coupled to a printed wiring board.
