A Guide to EMI Shielding Gasket TechnologyGreat Human Technology, INC. A Guide to EMI Shielding Gasket Technology Options in materials of construction, shielding effectiveness, and closure force abound, as this primer outlines. EMI shielding gaskets have been with us for more than 50 years, ever since those first electromagnetic waves began to wander where they were not wanted. An EMI shielding gasket is a conductive medium designed to fill equipment apertures and to provide a continuous low-impedance joint. It is technically definable as a flexible connection between two electrical conductors with a fixed resistance to current passing through it. The EMI gasket began as a randomly placed ground point, but gasket designs have evolved and diversified to match the growing proliferation of electronic equipment over the past half cen……
