Abstract
A method affixes a heat sink to a module lid. A module lid is mounted to a substrate by use of a lid adhesive. The module lid has a threaded exterior portion. The module lid is thermally interfaced to a die by use of a thermal interface material. The heat sink is then screwed onto a module lid, where the heat sink includes a threaded heat sink base pocket that mates with the threaded exterior portion of the module lid, and wherein the heat sink is screwed down onto the module lid until 1) a solid mechanical and thermal contact is established between the heat sink and the module lid, and 2) an airflow from an air moving device flows unobstructed across vanes on the heat sink.
