Copper sulfate(CuSO4) provides a source ofcopper ions. Sulfuric acid (H2SO4) makes the bath conductive and acts as a charge carrier. Chloride ions (Cl-) combine with the organic species to form a complex that slows down plating rate on selective areas.

As with electroplating with any metal, successfulcopper platingrequires precise execution to achieve the desired result. The following troubleshooting tips can ensure the best possible outcome during thecopper plating process: The right bath chemistry — Acopper plating bathcan be alkaline (cyanide or non-cyanide) or acid-based in composition. Choosing the most appropriate composition for the desired plating result can eliminate many commoncopper plating issues.
