Abstract
Abstract A grounding and supporting metal mesh provides connection between a circuit board with a cavity and a housing. The mesh is in the form of a spring made by interconnected torsional members. The mesh is plated with a metal which is compatible with the ground planes of the circuit board and housing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A metal mesh for electrically connecting the ground plane of a circuit board to the ground plane of a housing comprising a conductive material having an array of slits each defining a rectangular cross-section torsion bar affixed at the nodes such that when expanded each node forms a torsion spring, the material being a beryllium/copper alloy plated with a metal compatible with the material of said ground plane which is selected from the group consisting of nickel, tin and gold.
Claim 2
Dependent Claim
80 words
A metal mesh for electrically connecting the ground plane of a circuit board to the ground plane of a housing comprising a conductive material having an array of slits each defining a rectangular cross-section torsion bar affixed at the nodes such that when expanded each node forms a torsion spring, the material being a beryllium/copper alloy plated with a metal compatible with the material of said ground plane which is selected from the group consisting of nickel, tin and gold.
Claim 3
Dependent Claim
108 words
A hybrid circuit package comprising: a housing having a ground plane and a cavity exposing said ground plane; a metal mesh in the form of a plurality of torsion bars affixed at nodes to form a plurality of springy electrical contact points, said mesh being inserted within said cavity and having a certain thickness; a circuit board having a background plane, said circuit board being inserted in said cavity such that said background plane contacts said metal mesh; and means for securing said circuit board within said cavity so that said metal mesh provides a cushion and electrical connection between said housing ground plane and said background plane.
