Abstract:
The effect of plating bath in composition, pH ,temperature,time and volume on the electroless plated copper was studied. An alkaline electroless copper plating bath including copper sulfate as main salt, sodium hypophosphite as reducing agent, EDTA and sodium citrate as blending chelating agent,was established. A continuous self-catalyzed deposition of bright red-yellow copper coating on cast iron substrate was obtained successfully. Compared with traditional electro plated copper from cyanide-based plating, the electroless copper plating has a similar performence in the combination face to the substrate, better in brightness, and surface roughness of the electroless copper plating arrived at 8.
