COPETCH
Etching family under the name COPETCH is a part of all pretreatment sequences in highspeed plating systems. COPETCH products are compatible with all acids working with tin plating solutions. These products include also microetching to activate for example copper layer before next plating steps. Generally, COPETCH products include surfactants, inhibitors and catalysts with antifoam agents. Combination of these three groups is able to receive the etching process with “zero” lost weight.
