INVESTIGATION OF PLATINGS OF ELECTRICAL CONTACTS
Abstract
Deterioration of noble metal plated electric contacts by marine atmospheres has been determined in the interests of improving reliability and conserving precious metals. EIA, P-5.1 Committee Research Laboratories with this Laboratory investigated effects of marine and laboratory salt spray atmospheres on plated contacts to determine optimum platings. Work described includes establishment of experimental techniques, equipment development, marine exposure site at Ft. Tilden, N.Y., laboratory salt spray environment and procedures. Results indicate nickel underplating is undesirable, 0.000030-in. of gold over 0.000100-in. of silver is superior and 0.000030-in. of gold over 0.000100-in. of copper is adequate for Naval applications in a marine atmosphere.
