A nickel based alloy coating and a method for applying the nickel based alloy as a coating to a substrate. The nickel based alloy comprises about 0.1-15% rhenium, about 5-55% of an element selected from the group consisting of cobalt, iron and combinations thereof, sulfur included as a microalloying addition in amounts from about 100 parts per million (ppm) to about 300 ppm, the balance nickel and incidental impurities. The nickel-based alloy of the present invention is applied to a substrate, usually an electromechanical device such as a MEMS, by well-known plating techniques. However, the plating bath must include sufficient sulfur to result in deposition of 100-300 ppm sulfur as a microalloyed element. The coated substrate is heat treated to develop a two phase microstructure in the coating. The microalloyed sulfur-containing nickel-based alloy of the present invention includes a second phase of sulfide precipitates across the grain (intragranular) that improves the stress-relaxation resistance of the alloy.

Composition and method for applying an alloy having improved stress relaxation resistance

An electrical contact is provided that includes an elastomeric body extending between a base portion and a mating end portion. The elastomeric body includes a ledge extending from the mating end portion to the base portion of the elastomeric body. The ledge is defined by a portion of the elastomeric body. An electrically conductive pad extends over at least a portion of the mating end portion. An electrically conductive trace is formed on a surface of the ledge. The electrically conductive trace extends from the mating end portion to the base portion of the elastomeric body. The electrically conductive trace is in electrical contact with the electrically conductive pad for electrically connecting the electrically conductive pad with an electrically conductive element engaging the base portion of the elastomeric body.

Elastomeric electrical contact

An electrical interconnect device includes a substrate having opposite outer surfaces and an array of conductive elastomeric columns held by the substrate. Each of the columns have opposite ends that extend beyond respective ones of the outer surfaces of the substrate. Conductive contact caps are disposed over the opposite ends of each said column. An electrical path is defined from one of the contact caps, through the conductive elastomeric column, to another of the contact caps. Optionally, the contact caps may be sized and shaped substantially similarly as the ends of the elastomeric columns. The contact caps may be adhered to the ends of the columns, or alternatively, the contact caps may be adhered to the substrate.
