(ENIG) Plating for Printed Circuit Boards ASSOCIATION CONNECTING ELECTRONICS INDUSTRIES® 3000 Lakeside Drive, Suite 309S, Bannockburn, IL 60015-1249 Tel. @Kinwong, LLC 2014. • Silver Immersion • Tin Immersion • Tin-Lead Plating • Tin-Nickel Plating • Carbon • OSP • SMOBC • PISM • LPISM. Keywords: OSP, Surface Finish, Lead-free Test Board Description For this study, the current test vehicle that Flextronics uses for solder paste evaluation was used. The PCB is typically dipped into a bath of molten solder so that all exposed copper surfaces are covered by solder. * If this is a mixed technology board, OSP typically does not wet (accept solder) as well as some of the other finishes, and many folks have a tough transition over to no clean wave solder process with OSP products. In all cases OSP was used as the board finish. Printed circuit board plating is an electrochemical process in which a metal is deposited on the surface of a PCB, as well as inside of the plated through-holes.
