SpletPlating Finishes There are four different types of finishes available for the finished Circuit Boards: a) Bare Plating b) ENIG c) SILVER d) SMOBC (Solder Mask On Bare Copper) e) Tin/Lead Plating- HASL. Resist Strip The PCB’s are dunked into the Resist Strip liquid solution. Here the exposed film is dissolved and stripped removing the dry film. SpletElectroless nickel immersion gold (ENIG or ENi/IAu), also known as immersion gold (Au), chemical Ni/Au or soft gold, is a metal plating process used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improve the solderability of copper contacts and plated through-holes.It consists of an electroless nickel plating, covered with a thin … Spletprimary metallization process such as electroless copper, a carbon-based direct metallization, or a conductive polymer to make via walls initially conductive. This is then followed by an imaging process and pattern plating with an acid copper electrolyte. The pattern plating is done both to fill the microvias completely with copper and build the drugs avoided during pregnancy
