An electromagnetic shield includes an electrically conductive contact strip arranged to form a perimeter fence. The contact strip used to form the shielding fence is oriented such that the contact fingers are vertical to the printed circuit board and the spring fingers face inward toward a heat producing device. A shielding lid, which also functions as a heat sink for cooling the device, makes electrical contact around the perimeter thereof by sliding down across the contact portions of each finger of the fence, and thereby coming to rest on the heat producing device, either directly or through a thermally conductive interface. A spring clip which holds the heat sink in place over the heat producing device is designed to clip into opposite sides of the perimeter fence below the row of spring fingers, thereby forming a unitary shielding and cooling device. |
