Abstract
A new gasket technology has been developed for ElectroMagnetic Interference (EMI) containment which has proven to be superior to conventional pressurefit gaskets for both performance and reliability in marry applications. The gasket consists of a flexible, conductive diaphragm which is held to a cavity opening by means of a magnetic strip. This technology results in a high shielding effectiveness (SE) over a wide frequency range with almost no degradation in performance over life. Testing has demonstrated an average SE 20 to 30 dB superior to that possible from conventional gaskets between 20 MHz and 5 GHz.
