US Classification:

257762, 257635, 257700, 257748, 257758

Abstract:

A coated electrically conductive substrate has particular utility where there are multiple closely spaced leads and tin whiskers constitute a potential short circuit. This electrically conductive substrate has a plurality of leads separated by a distance capable of bridging by a tin whisker, a silver or silver-base alloy layer coating at least one surface of at least one of the plurality of leads, and a fine grain tin or tin-base alloy layer directly coating said silver layer. An alternative coated electrically conductive substrate has utility where debris from fretting wear may increase electrical resistivity. This electrically conductive substrate has a barrier layer deposited on the substrate that is effective to inhibit diffusion of the substrate into a subsequently deposited layers, which include a sacrificial layer deposited on the barrier layer that is effective to form intermetallic compounds with tin, and a low resistivity oxide metal layer deposited on the sacrificial layer. An alternative coated electrically conductive substrate has particular utility where debris from fretting wear may oxidize and increase electrical resistivity, such an in a connector assembly. This electrically conductive substrate has a barrier layer deposited on the substrate that is effective to inhibit diffusion of constituents the substrate into a plurality of subsequently deposited layers.

US Classification:

148554, 148685

Abstract:

A copper alloy having an improved combination of yield strength and electrical conductivity consists essentially of, by weight, from 1% to 2. 5% of nickel, from 0. 5% to 2. 0% of cobalt, with a total nickel plus cobalt content of from 1. 7% to 4. 3%, from 0. 5% to 1. 5% of silicon with a ratio of (Ni+Co)/Si of between 3. 5 and 6, and the balance copper and inevitable impurities wherein the wrought copper alloy has an electrical conductivity in excess of 40% IACS. A further increase in the combination of yield strength and electrical conductivity as well as enhanced resistance to stress relaxation is obtained by a further inclusion of up 1% of silver. A process to manufacture the alloys of the invention as well as other copper-nickel-silicon alloys includes the sequential steps of (a). casting the copper alloy; (b). hot working the cast copper-base alloy to effect a first reduction in cross-sectional area; (c).

Abstract:

An age-hardening copper-base alloy and processing method to make a commercially useful strip product for applications requiring high yield strength and moderately high electrical conductivity, in a strip, plate, wire, foil, tube, powder or cast form. The alloys are particularly suited for use in electrical connectors and interconnections. The alloys contain Cu—Ti—X where X is selected from Ni, Fe, Sn, P, Al, Zn, Si, Pb, Be, Mn, Mg, Ag, As, Sb, Zr, B, Cr and Co. and combinations thereof. The alloys offer excellent combinations of yield strength, and electrical conductivity, with excellent stress relaxation resistance.
