Abstract:
1. A shielded circuit board assembly, comprising: a circuit board having a top side, a ground plane conductor trace on the top side defining a peripheral margin, and a plurality of holes formed in the margin; and a first electromagnetic shield surrounding electronic components mounted on the top side of the circuit board within said margin, said shield including a sheet metal top that covers the electronic components, depending sidewalls that abut the top side of the circuit board, a first set of sidewall legs having buckles that pass through the holes formed in the margin of the circuit board to provide snap-fit attachment of the shield to the circuit board, a second set of sidewall legs that extend through the holes formed in the margin of the circuit board, including end portions that protrude through the circuit board and are twisted to mechanically lock the shield to the circuit board, and teeth formed in the sidewalls that bite into a the ground plane conductor trace on the top side of the circuit board when said shield is attached to said circuit board to provide electrical coupling between said shield and said ground plane conductor trace.
