Abstract
A PC card is provided with internal electromagnetic shielding to isolate two or more different circuit component areas of the card, which facilitates mounting of the shielding. In one card which is an extended card having a standard forward portion (102) containing electronic components, and having an extended rearward portion containing an antenna (100) for radiating electromagnetic energy, the shielding includes a strip-shaped portion (22) of electrically conductive material that extends across the width of the circuit board and that has opposite ends that terminate near the intersection between the two card parts, with the shielding having pins (31) that project into holes (150) in the circuit board. In another PC card a plate-like filler (38, 39)which lies between the circuit board (151) and a sheet metal cover part, has a plurality of holes (41-47), and strip-like shielding (21') extends around the periphery of the hole and is mounted thereat to the filler, with the shielding extending above and below the filler and contacting the sheet metal cover part and the circuit board.
