Abstract
Abstract An apparatus for interfacing materials and absorbing disparate thermal expansions thereof utilizes a woven wire mesh to support a predetermined thickness of a first soft solder which absorbs expansions, and utilizes a second soft solder having a lower melting point than the first to coat the surfaces of the wire mesh/first soft solder combination so that the materials can be bonded thereto.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
171 words
An apparatus for grounding an electrically conductive material comprising: a first material comprising an electrically conductive ground plane, a second material having a top and bottom surface, said top surface being electrically conductive, a woven wire mesh having electrically conductive longitudinal and lateral wires, a first soft solder filler disposed around said longitudinal and lateral wires forming thereby substantially planar surfaces on both sides of said wire mesh, and a second soft solder having a lower melting point than said first solder for coating planar surfaces of said soft solder filler, wire mesh combination, said wire mesh filled and coated with said first and second solder being disposed between said ground plane and said bottom surface of said second material, peripheral edges of said solder filled and coated wire mesh being folded over said second material such that said electrically conductive top surface is in electrical contact with said solder filled and coated wire mesh thereby providing an electrically conductive path from said electrically conductive top surface to said ground plane.
