摘要:我国无氰电镀铜工艺研究取得了丰硕的成果。已投产使用的有哈尔滨工业大学研究并获国家发明奖的柠檬酸-酒石酸盐镀铜和南京大学为主研究的羟基乙叉二膦酸（HEDP）直接无氰镀铜工艺，经投产实验表明，这两种电解液的成分稳定，分散能力和覆盖能力好，镀层与集体的结合力较强。
本实验旨在研究柠檬酸盐体系下加入其它单一的电镀辅助络合剂来得到表面细致，镀层与基体结合力较强的工艺配方。然后对该配方进行优化实验，改变各种实验条件和成分含量来得到最佳的工艺配方。31977
经实验得到以下结果：
单一辅助络合剂的柠檬酸盐体系的最佳配方为：柠檬酸钾200g/l，硫酸铜40g/l，胺类化合物50g/l，pH为9-10，温度60℃。此配方得到的镀层表面细致。

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
