Abstract
A heat sink retention module provides physical support for a heat sink while providing an electrical ground path for the heat sink. The retention module includes a ground strip that maintains an electrical contact with the heat sink while contacting a circuit board ground connection. In one embodiment, the ground strip includes upwardly extending spring members that contact the heat sink. In another embodiment, the ground strip includes a Faraday Cage formed from downwardly extending tabs. The retention module can be used in conjunction with an electrically conductive heat sink to provide a ground plane over an integrated circuit to shield the circuit from electromagnetic interference.
