ABSTRACT:
An electronic device employs a method and apparatus for shielding an electrical circuit (101) that is disposed on a substrate (120). A base member (103) that includes a top portion (104) and a plurality of side portions (105) is electrically coupled to a receptacle area (121) of the substrate (120) such that the plurality of side portions (105) substantially encircle the electrical circuit (101). The top portion (104) of the base member (103) includes a plurality of tab members (108) interposed with a plurality of receptacle openings (109). A substantially planar cover (102) that includes a plurality of protrusions (111) is positioned adjacent to the top portion (104) of the base member (103) such that each protrusion (111) is positioned within a corresponding receptacle opening (109). The cover (102) is then urged until each protrusion (111) interlocks with a corresponding tab member (108) to substantially enclose and, thus, shield the electrical circuit (101).
