合成了一种半胱氨酸亚金的无氰、腈金化合物盐.以该亚金配合物为研究平台,开展了ENIG(化镍金)工艺研究.得到的最佳化学镀金工艺参数为:温度45~65 ℃,pH值1. 5~2. 5,亚金2.0~2.5 g/L,配体[Lig] 10~25 g/L.在此条件下,可以获得晶粒细小均匀、结合力好的化学镀金层.

A cyanide-free aurous-cysteine compound salt was synthesized, and this aurous complex was used as a research platform to carry out the research on ENIG process. The optimal process parameters of electroless gold plating were determined as follows: temperature 45 ~ 65 ℃, pH value 1. 5 ~ 2. 5,aurous 2. 0 ~2. 5 g/L, ligand[Lig] 10 ~25 g/L. Under these conditions, the obtained electroless gold coat...
