Abstract
A PC card with a circuit board (14) and sheet metal cover parts (16, 17), is provided with a shielded volume (23, 29) where a circuit component (24) is isolated from circuit components outside the shielded volume. An internal shield (18) of electrically conductive material surrounds the shielded volume, and is engaged with a ground trace (28) on the circuit board. The internal shield is flexible so it bends when the sheet metal cover parts bend, to avoid breaking the circuit board. Layers of electrically conductive adhesive (42, 44, 46) couple the internal shield to the circuit board into one of the cover parts. A plate-like shielding device (40) can be provided, that includes a metal foil (41) that is bonded to the internal shield and that lies over the entire shielded volume.
