ABSTRACT:
An electromagnetic shield for absorbing electromagnetic energy generated by a circuit disposed upn a circuit board. The shield is comprised of a thermally conductive material to further provide heat-sink capabilites. Clip members releasably fastened to a flange projecting from a shielding surface formed by the shield are aligned with the ground plane of a circuit board. By maintaining the shield in a confronting relationship with the circuit board, the clip members are caused to maintain the shielding surface in electrical contact with the circuit.
