Copper and Nickel Stripper

General Information

TechniEtch™CN10 is a Copper and Nickel Stripper, which is a mixture of Nitric- and Phosphoric acid.

The etching process should be carried out with an addition of 8-16 % Hydrogenperoxide (30 %).
At 25° C the etching rate is approx. 0.3-0.4 µm per minute. Without the Addition of Hydrogenperoxide the etching rate is significantly lower and less homogenous.
