Publication number: 20010009724Abstract: Deposition of metal in a preferred shape, including coatings on parts, or stand-alone materials, and subsequent heat treatment to provide improved mechanical properties. In particular, the method gives products with relatively high yield strength. The products often have relatively high elastic modulus, and are thermally stable, maintaining the high yield strength at temperatures considerably above 25° C. This technique involves depositing a material in the presence of a selected additive, and then subjecting the deposited material to a moderate heat treatment. This moderate heat treatment differs from other commonly employed “stress relief” heat treatments in using lower temperatures and/or shorter times, preferably just enough to reorganize the material to the new, desired form. Coating and heat treating a spring-shaped substrate provides a resilient, conductive contact useful for electronic applications.Type: ApplicationFiled: January 29, 2001Publication date: July 26, 2001Inventors: Jimmy Kuo-Wei Chen, Benjamin N.

Patent number: 5779873Abstract: This invention is predicated on the discovery by the present applicants that boric acid in conventional nickel plating baths is responsible for excessive lateral growth in the electroplating of nickel on nickel ferrite substrates. While nickel baths without boric acid do not yield acceptable electrodeposits, the boric acid interacts with the ferrite substrate to cause excessive lateral growth. Applicants further discovered that by eliminating the boric acid and adding another acidic plating buffer such as citric acid, one can obtain isotropic nickel plating and produce a wire-bondable surface.Type: GrantFiled: December 18, 1996Date of Patent: July 14, 1998Assignee: Lucent Technologies Inc.Inventors: Henry Hon Law, Lynn Frances Schneemeyer, Te-Sung Wu
