Abstract:
1. An apparatus for dissipating heat and shielding electromagnetic radiation from at least one integrated circuit on a printed circuit board, the apparatus comprising: a printed circuit board comprising a plurality of layers including an inner conducting layer and an exterior layer having a surface with at least one integrated circuit disposed thereon and an electrically conductive region surrounding the at least one integrated circuit, the printed circuit board having a row of electrically conductive through-holes located adjacent to and along one side of the electrically conductive region, the electrically conductive through-holes being in electrical communication with the electrically conductive region and with the conducting layer; and an electrically conductive cover portion having a top surface and a bottom edge, the top surface having at least one heat-dissipating structure extending therefrom and the bottom edge being in electrically conductive contact with the electrically conductive region of the printed circuit board, the electrically conductive cover portion defining a cavity that encloses the at least one integrated circuit on the surface of the printed circuit board to shield electromagnetic radiation, the at least one integrated circuit being in thermally conductive communication with the electrically conductive cover portion for transferring heat thereto to be dissipated by the at least one heat-dissipating structure.
