Abstract
Abstract An RF shielding gasket is formed as a conductive foil lamina bonded to a compressively resilient foam backing by a flexible adhesive and mounted on a cover by pressure-sensitive adhesive coating on the back of the foam lamina so when the cover is closed over a cabinet containing electronic equipment, the foil is held in intimate contact with the cabinet by the resilient foam lamina.
