Abstract

The present invention places a semi-lossy gasket between a printed circuit board ground pad ring and a metal shield can for shielding electronic components and circuitry which generate electromagnetic radiation. The present invention also provides a variety of means for aligning and mounting the shield can and gasket to the printed circuit board. Guide pins extending from the shield can extend through apertures in the printed circuit board for aligning the shield can to the printed circuit board. The guide pins can be bent or soldered to the printed circuit board and can also include a hooked end for latching on to the printed circuit board.
