Abstract: A system, i.e. method and materials for RFI/EMI shielding an electronic module in a computer or other electronic product is described. In one embodiment of the invention predetermined areas of the module, such as connectors, mounting holes, and electrically insulated portions of the cases of high heat-dissipation electronic devices of the module, are masked. Thereafter, a relatively tichk, substantially continuous, electrically insulating conformal coating, in liquid state, is applied to all exposed surfaces of the module by a suitable technique, such as dipping or spraying. The preferred coating is a polymer-resin coating of a predetermined high viscosity and may be applied unfilled or filled with an electrically-insulating, thermally-conductive solid, such as powdered metal oxide, e.g. aluminum oxide. The applied conformal coating is set or cured, and a substantially continuous electrically conductive coating is applied over the insulating coating by a suitable technique, such as spraying or plating.

Abstract: A non-glare, electromagnetic interference rejecting screen for a video display terminal. The screen comprises a front panel, formed of a transparent material, a rear panel, formed of a transparent material and a woven mesh screen interposed therebetween. A gasket is disposed about the front panel, with peripheral edge portions of the screen extending over the gasket. The screen is mounted on the display terminal so that the wire mesh is interposed between the gasket and the screen retaining frame, e.g., bezel, to form a good electrical interface therebetween. The strands of the screen are disposed at right angles to one another, with none of said strands being disposed horizontally or vertically. The strands are formed of electrically conductive material and are coated with silver. The silver surface is in the form of silver sulfide to give a darkened appearance.
