military,medical,industrial Connector plating on connectors can
ensure connection performance and avoid corrosion, oxidation, etc, especially
in harsh environment, military connectors, aerospace connectors and also
industrial and medical connectors.
Below is plating material details:
Tin (Sn)
Tin plating type is pre-electroplating,
pre-cladding, plating. Tin is soft and anti-corrosion with cheap price. Easy to
solder, common thickness is 2~4mm, matte or glossy silvery.
Gold (Au)
The best advantage of gold plating is very soft
material, anti-corrosion, insoluble in pure acid, good electroconductivity, but
very expensive. So elective gold plating is very popular. Gold plated over nickel,
common thickness 0.4~3.5mm.
Palladium (Pd)
Palladium can be applied instead of gold plating
sometimes.
Nickel (Ni)
Silvery, electroconductivity and weldability is not
good, after painted, it is hard and smooth, can be applied for base plating
before gold plating.
Silver (Ag)
Gloss white, soft, good electroconductivity and
weldability, but very expensive and silver tarnish quickly.
Copper (Cu)
