A one-piece electromagnetic circuit board shield has a series of depending legs that extend through corresponding slot openings in a circuit board for mechanically retaining the shield in place on the circuit board, and intervening teeth that bite into a peripheral ground plane conductor trace on the circuit board to provide reliable electrical coupling between the shield and the ground plane conductor trace. Some of the depending legs have buckle features that pass through the circuit board slots with resistance to provide a snap-fit attachment of the shield to the circuit board, and other depending legs of the shield are contoured to facilitate a twist-lock functionality that provides a vibration-resistant mechanical lock between the shield and the circuit board.
