Conductive Gaskets

Conductive Gaskets
Conductive gaskets are primarily used to minimize the transfer impedance between conductive ground planes and to provide a continuous electrical seal between conductive, EMI/RFI shielding filters, and the mounting surface of the shielded enclosure. Conductive gaskets can be comprised of metal (e.g., knitted wire mesh, spring fingers, metal helicoils), conductively loaded form-in-place, strip or die cut elastomers and fabric-over-foam materials. EMI/RFI shielding is improved by minimizing the transfer impedance at the interface between the filter and the enclosure or bezel. Consequently mechanical, electrical, galvanic and thermal properties, as well as bus termination must be considered to optimize the performance of conductive gaskets.
