Abstract
A masking tape for EMI shielding applications comprising an adhesive layer, a metal foil layer adhered to the top of the adhesive layer, two or more adhesive strips running parallel to the edges of the tape and extending the length of the foil along the strips are preferably inset from the outer edges of the foil so as to form a stepped or notch-like configuration. A mask layer is attached to the top of the strips. The mask alone or the mask and strips are designed to be removed after use. The tape is applied to a substrate such as a computer cabinet, the cabinet is then sprayed with a paint or finish coat and the mask is removed to reveal a conductive metal foil surface to which a conductive EMI shield can be mounted.
