Abstract:
1. An integrated circuit package comprising: a substrate; a die coupled to the substrate; and a lid coupled to the die, the lid comprising a plurality of electrically conductive projections along the periphery of the lid, the lid extending beyond the sides of the substrate to form an overhang, the plurality of projections extending downwardly from the overhang of the lid outside the substrate, wherein the plurality of projections are spaced from each other to define a plurality of air gaps along the periphery of the lid, the plurality of air gaps being configured to form a plurality of openings when the integrated circuit package is coupled to a circuit board, the plurality of openings being configured to allow heat to be rejected to the surroundings of the integrated circuit package from at least one side of the substrate directly by radiation and convection when the integrated circuit package is coupled to the circuit board, wherein the plurality of projections are adapted to electrically couple the lid to a ground plane of the circuit board during use, and wherein the plurality of projections are configured to contain EMI produced in the integrated circuit package during use.
