Copper plating can be from matte to a very shiny finish. It has good corrosion resistance when used as a undercoat for other plated coatings.
There are a number of copper plating processes available, each designed for a specific purpose, and ranging from decorative to heat treat stop-off.
|Class 0||.001 – .005″ for heat treatment stop-off shield|
|Class 1||.001″ min. for carburizing shield, decarburizing shield and printed circuit board plated through holes.|
|Class 2||.0005″ min. as under coat for nickel and other metals|
|Class 3||.0002″ min. to prevent basis metal migration into tin layer to poison solderability|
|Class 4||.0001″ min. same as Class 3|
