Pin holes and pitting in copper plating of Ni Cr plated plastics [India] 

January 18, 2006

We are tier 1 supplier for plastic Ni Cr plated parts to OEMs.

Presently, we are facing the problem of pinholes or pitting after plating especially from the copper bath and these pinholes or pittings are on top surface of the component.

Can somebody help me to resolve this issue.....

Chloride contamination in your copper tank and Impurity from your anodes is where to start looking first; additives next.

Are all your chemicals in range? How high is the trivalent chrome in the etchant solution? Any organic overdoses in Copper and/or Nickel? How are the rinses?
