Cherng Yi Hsing (CYH) Plating Thickness Test
The purpose of the copper strike is to build up sufficient copper thickness (0.0001inch) to prevent loss of electrical contact to the rack. A bright acid copper bath builds a thickness of about 0.0005 to 0.001 inch of bright copper. This ductile copper prevents blisters and cracks and levels any small cosmetic defects to prepare the surface for subsequent satin nickel plating.
Plated thickness is critical to performance parameters such as durability, conductivity, hardness and lubricity. Auto accessories are examined using chemicals to test out the plating thicknesses and ensure their thicknesses meet the standards.
