A shield can (16) for radio frequency (RF) shielding of electronic circuitry mounted on or embedded in the surface (14) of an insulating substrate such as a printed circuit board (PCB) (10). The design of the shield can (16) allows it to conform to variations in the surface (14) of the PCB (10). The shield can (16), which is usually formed of metal, comprises a top (18) and a plurality of side walls dimensioned to completely cover the electronic circuitry when the shield can (16) is placed over the circuitry. According to the present invention, any of the sides of the shield can (16) may be made to conform to the surface (14) of the PCB (10) (and to effectively contact a ground trace (12) on the PCB (10)) by providing a plurality of vertical slots (24) in the side. The slotted side would then comprise a series of metal teeth (22) each of which can be displaced angularly to the extent required to conform to the PCB (10) when a modest force (40-44) is applied to the top (18) of the shield can (16). |
