Assignee:

Parker-Hannifin Corporation - Cleveland OH

International Classification:

H05K 900

US Classification:

174 35GC, 277920

Abstract:

A combination EMI shielding and environmental sealing gasket construction and method for its manufacture. The gasket includes at least one electrically-conductive EMI shielding gasket member, and at least one environmental sealing gasket member. The shielding gasket member, which may be in the form of a strip, has a lengthwise extent and an outer periphery having interstitial spaces, such as between the fibers of a metal wire or other fiber mesh or fabric, through a widthwise extent thereof. The sealing gasket member extends along the lengthwise extent of the shielding gasket member and is formed, such as by being dispensed to foam or otherwise formed-in-place along an adjacent side of the strip, of an elastomeric foam or other material which penetrates into at least a portion of the interstitial spaces of the shielding gasket member to bond the shielding gasket member and the sealing gasket member into an integral structure.

Abstract:

Manufacture of an electromagnetic interference (EMI) shielding cover or other enclosure part for housing circuitry of an electronic device. The enclosure part has an exterior surface and an opposing interior surface metallized with an electrically-conductive EMI shielding layer. The layer is sprayed onto the interior surface in a molten state and is solidified to form a corrosion-resistant, self-adherent coating.
