Patent ID: 7765687

Claim:
A method of packaging electronics comprising: providing the electronics on a printed circuit board having connecting pins extending from opposite ends thereof; sliding the printed circuit board, beginning with one end of the circuit board having connecting pins, into an open end of a four sided metal case, where two opposite sides of the metal case are parallel to faces of the printed circuit board; with the connecting pins extending from opposite ends of the case, locking the printed circuit board in place within the metal case by extending locking pins through holes in the metal case and then into the printed circuit board, wherein each locking pin has a head recessed in a bottom of the metal case and the bottom of the metal case is mounted to a heat removal plate external to the case, so that each locking pin is entrapped between the case and the heat removal plate when the metal case is mounted to the heat removal plate; and filling the case with a thermally conductive potting material to provide thermal conduction from the printed circuit board to the case.
