Abstract
An arrangement for providing radio frequency and electromagnetic interference protection to at least part of circuitry mounted on a circuit board comprises alternating slots and bridges which form a boundary between a protected area of the circuit board and an unprotected area of the circuit board. The circuit portions which require protection are mounted in the protected area and are covered by a top cover having fingers which extend through the slots. Connecting lines between the protected and unprotected portions of the circuit portions extend along the bridges between the slots. A bottom cover engages under the protected area and mates to the top cover for providing electromagnetic interference protection for the circuit portions within the protected area.
