ABSTRACT:
An electrical circuit (101) that is disposed on a substrate (103) employs a method and apparatus for providing electromagnetic shielding of the electrical circuit (101). One or more compressible, electrically conductive contacts (107), each of which includes a substantially planar portion (201), are coupled at their respective planar portions (201) to a receptacle area (105) on the substrate (103) that substantially encircles the electrical circuit (101). A shielding enclosure (109) having a top portion (110) and a plurality of side portions (111) is positioned upon the compressible, electrically conductive contacts (107) such that the side portions (111) compress at least some of the compressible, electrically conductive contacts (107) to substantially enclose the electrical circuit (101).
