Plating Characteristics

Plating Type	Overall Thickness	Salt Spray Test	Pressure Cooker Test
NiCuNi (Nickel Copper Nickel)	15-21 μm	24 hours	48 hours
NiCu + Black Nickel	15-21 μm	24 hours	48 hours
NiCuNi + Epoxy	20-28 μm	48 hours	72 hours
NiCuNi + Gold	16-23 μm	36 hours	72 hours
NiCuNi + Silver	16-23 μm	24 hours	48 hours
Zinc	7-15 μm	12 hours	24 hours

Each individual layer of Nickel and Copper are 5-7 μm thick. The Gold and Silver plating layers are 1-2 μm thick.
Test results shown to allow comparison between plating options. Performance in your application under your specific test conditions may vary. Salt Spray testing conducted with a 5% NaCl solution, at 35°C. Pressure Cooker Test (PCT) conducted at 2 atm, 120°C at 100% RH. Process Chart :
