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