Abstract:
A method (100) for silver plating an electrical contact is provided. The method includes cleaning an electrical contact by removing oil (104) or other contaminants and exposing the electrical contact to at least one of an acid or base (108). The method also includes preparing a silver plating bath including a silver compound, a transition metal compound, and a supporting salt, wherein the transition metal is at least one of nickel or cobalt. The method further includes silver plating (112) the electrical contact in the silver plating bath.
Abstract:
A system for manufacturing electrical components includes a reflow chamber having an inlet port and an outlet port. The inlet port receives a web of interconnected electrical components having a conductive coating into the reflow chamber. The outlet port discharges the web from the reflow chamber. The reflow chamber directs the web of interconnected electrical components along a predetermined pathway through the reflow chamber. The reflow chamber retains a heated and saturated vapor to heat the conductive coating as the web passes along the pathway through the chamber to reflow the conductive coating about the electrical components.
Abstract:
An electrical conductor (100) has a metal substrate (102). A seal plating layer (104) is provided on and exterior of the metal substrate. A nickel plating layer (106) is provided on and exterior of the seal plating layer. A gold plating layer (108) is provided on and exterior of the nickel plating layer. The seal plating layer is a non-nickel based metal. Optionally, the seal plating layer may be tin based. Optionally, the seal plating layer may create intermetallic interfaces (112, 114) with the nickel plating layer and the metal substrate. Optionally, the electrical conductor may constitute a contact configured for mating with at least one of a printed circuit board or another mating contact.
