Abstract
A fabric over foam electromagnetic interference gasket has a body of indefinite length, and includes a layer of dielectric material thereon. The gasket may be compressed between two substrates and provide electrical conductivity in one axis and EMI shielding and nonconductivity in a perpendicular axis.
Claims20
An electromagnetic interference gasket comprising a body of indefinite length and including:
- a core surrounded by an electrically-conductive layer, where the electrically-conductive layer is adhered to the core;
- and
- a nonconductive layer adhered to the electrically-conductive layer along one or more opposite sides of the gasket that are configured to deflect outwardly when the gasket is compressed between first and second surfaces.
A method of manufacturing an electromagnetic interference gasket having a body of indefinite length, the method comprising;
- surrounding a foam core of indefinite length with an electrically-conductive layer and adhering the electrically-conductive layer to the core;
- and
- adhering a nonconductive layer to the electrically-conductive layer along one or more opposite sides of the gasket that are configured to deflect outwardly when the gasket is compressed between first and second surfaces.
A method comprising compressing an electromagnetic interference gasket between first and second surfaces such that opposite sides of the gasket deflect outwardly, wherein the gasket comprises a core surrounded by an electrically-conductive layer that is adhered to the core, and a nonconductive layer adhered to the electrically-conductive layer along one or more of the opposite sides of the gasket, whereby the gasket provides electrical conductivity between the first and second surfaces with the nonconductive layer preventing electrical contact with and shorting out of an adjacent electrical component in contact with the nonconductive layer.
