<p>A conductive gasket is disclosed for use in apparatus to block the exit or entry of electromagnetic interference (EMI) between adjacent metal surfaces of the apparatus. The gasket is formed at least in part by a polymeric film having an outward facing surface embossed so as to provide a plurality of peaks distributed over the surface. A metal is coated, by vapor deposition, onto the surface so as to over lie the peaks. This provides the film with a conductive surface. When located between adjacent metal surfaces, abrasion of the metal coating from the peaks over time does not adversely affect the conductive properties of the film surface. This is because the wearing away of the metal from the tops of the peaks exposes a cross section of the metal at the sides of the peaks, which remain in contact with the adjacent metal surfaces of the apparatus.</p> |
