Method and apparatus for EMI shielding
First Claim
1. An extensible conductive coating characterized at least in part by a surface resistivity, the extensible conductive coating comprising conductive fibers and an extensible film, wherein the conductive fibers are integrated into the extensible film such that the surface resistivity in an formed state is no more than about 20 times the surface resistivity in an unformed state, per drawn inch.

Abstract
Disclosed are methods for manufacturing electromagnetic interference shields for use in nonconductive housings of electronic equipment. In one embodiment, the shield may include an electrically nonconductive substrate, such as a thermoformable film, coated with an electrically conductive element, such as an extensible ink or a combination of conductive fibers with an extensible film. In one embodiment, a compressible conductive perimeter gap gasket may be formed by using a form in place process.
