There are many types of surface finish used for plating the printed circuit boardspcb.E.G.Organic surface protectant osp, immersion silver iag, immersion tin, electroless nickel with immersion gold coating enig, and direct gold plating over nickel.Among them, hasl and enig have been dominating the market for decades.
Enepig surface finish is the low-cost alternative to direct soft gold plating.Enepig surface finish is ideal for soldering, aluminum wire bonding, and gold wire bonding.This surface finish is formed by the sequential deposition of nickel, followed by palladium, followed by immersion gold.

Chat OnlineWhich pcb surface finish should i use at the most basic level, a pcb surface finish is a plating or coating that is applied to the exposed copper of a circuit board.The surface finish not only protects the copper from oxidation, but also forms the foundation of connectivity between a pcb and a component.
Chat OnlineChoosing the right surface finish for your pcb is as important as choosing a manufacturer to make the pcb.Use the wrong surface finish and it you may have downstream issues during assembly or longer-term reliability issues.The surface finish is a protection against the elements, in short it is designed to protect soldering pads and contact.
Chat OnlineThe most widely used surface finish is hasl hot air solder leveling.The process in which this is produced is by dipping the pcb into molten solder and then the excess is cleaned off using hot-air knives to leave behind the thinnest possible layer of solder.
Chat OnlineA surface finish can be either organic or metallic in nature.Comparing both types and all available options can quickly demonstrate the relative benefits or drawbacks.Typically, the decisive factors when it comes to selecting the most suitable finish is the end application, the assembly process and the design of the pcb.
