Nicken-Phospho Cho Linh Kiện Điện Tử
This combination does not exist.
Coating system for connectors
With NIPHOS® 965 nickel-phosphorus alloy layers can be deposited in reel-to-reel electroplating systems or other high speed systems. In comparison to high-phosphorus containing electroless nickel layers, nickel-phosphorus layers produced by electrolytes are amorphous, diamagnetic, abrasion and corrosion resistant as well.
It is possible to work with soluble anodes (nickel), insoluble anodes (platinum-plated titanium or MMO) or a combination of both. The lifetime is almost unlimited and corresponds to the one of bright nickel electrolytes.
NIPHOS® is insensitive to contaminations with metallic particles. In contrary to electroless nickel it does not tend to random plating. Also the electrolytes are free from halides and contain no other heavy metals such as lead or cadmium, besides nickel.
NIPHOS® 965 is chloride-free and pH-stable during operation. The phosphorus content of the coatings is 6 - 12 %. The hardness of the layers is 550 HV 0.05 as plated without heat treatment. NIPHOS® 965 coatings are applied prior to hard-gold plating (e.g. AURUNA® 8100) of contact surfaces.
