Abstract
An apparatus is provided to reduce the amount of EMI generated by a circuit. The grounding of an enclosure is improved by providing a number of shaped protuberances, the protuberances having an end that penetrates a conductive region of a circuit board, such that when the circuit board is mounted to the support member, the protuberances make a penetrating electrical contact and provides for additional ground paths, thereby reducing the EMI generated by the assembly.
