ABSTRACT:
Electromagnetic shielding apparatus for portable telephones (300) and other electronic equipment, includes shield clips (100) for intercoupling the conductive surfaces of a housing (302 and 303) to the metal layer (205) of the circuit board (200). Each shield clip (100) mates with a corresponding edge (204) of the circuit board (200) such that tabs (208, 209, 210) insert into holes (108, 109, 110) in the central channel (111--113) of the clip (100) and feet (101, 102, 103) of the clip rest on other tabs (201, 202, 203). The clip (100) is bonded to the metal layer (205) of the circuit board preferably by resistance welding, thereby reliably connecting the clip (100) and the conductive housing surfaces to signal ground.
