Abstract
A shielding effectiveness curve is illustrated that can be used (when Electromagnetic Interference (EMI) gaskets are not used) to predict a level of shielding as a function of screw spacing and the wavelength of any frequency of interest. The test requirements for a design engineer to properly select an EMI gasket for a specific application are listed. These include (1) the conductivity of the gasket against any of the materials and finishes used by industry; (2) the level of shielding as a function of the force of a gasket against the faying surfaces of a system as applied to the materials and finishes used by industry; and (3) the effect moisture and salt fog environments have on the shielding of the gasket against the various surfaces and finishes used by industry.
