Abstract
A sheet metal cover for a printed circuit board (PCB) includes a plurality of legs continuous with a substantially planar elevated section. The legs are attached to the PCB, and electrical connections are provided between the legs and an internal ground plane of the PCB at the attachment locations. The sheet metal cover is thereby grounded, inhibiting the transmission of electromagnetic signals through the sheet metal cover. The elevated section of the sheet metal cover prevents select electronic devices on the PCB from being viewed or probed. Openings through the sheet metal cover allow heat sinks or heat generating electronic devices (e.g., inductors) to be exposed through these openings, thereby facilitating cooling of these elements by airflow. An electrically conductive gasket attached to the underside of the elevated section may contact the heat sinks, further minimizing the radiation of EMI emissions.
