Alkaline copper plating technology research
Abstract：Without cyanide copper plating technology research in China has come to a great achievement. The technology studied by Harbin Institute of Technology which won the national award for its salt of citric acid and tartaric acid copper plating and the technology of hydroxy ethyl fork phosphonic acid (HEDP) without cyanide copper plating process directly which is studied by Nanjing University have been put into operation. The production experiments showed that the two kinds of electrolyte composition is stable, dispersion ability and coverage are good, plating and the adhesion strength of the collective is stronger.
The experiment was aimed to study citrate system which is injected other single electroplating auxiliary complexing agent to get a technological formula that the plating surface is meticulous and having a strong binding force between the coat and the substrate. Then, I will have a optimization experiment,changing various experimental conditions and the component content to get the best technology formula.
Through the experiment to get the following results:
Single auxiliary complexing agent system of citrate best formula is: potassium citrate 200g/l, copper sulfate 40g/l, amine compounds 50g/l, pH of 9 to 10,the temperature is 60 ℃. The coating on the surface of this formula is fine.
Key words: Alkaline copper plating,citrate copper plating,auxiliary complexing agent
