A electromagnetic interference (EMI) grounding unit provides an electrical connection between a heat sink and a ground formed on a substrate. A tab mechanically and electrically continuous with an electrically conductive generally planar member makes electrical contact with the heat sink. The electrically conductive generally planar member is connected to one or more conductive posts. And the one or more conductive posts are connected to the ground. An electrical charge on the heat sink is discharged along a path that includes the tab, the electrically conductive generally planar member, and the one or more posts. Discharging accumulated charge on the heat sink to ground reduces EMI generated by re-radiation of electromagnetic energy from the heat sink.
