摘　　要：为了满足环保要求,近年薄膜电路加工越来越多的采用亚硫酸盐镀金,但亚硫酸盐镀金液稳定性较差,金层硬度上升较快,造成亚硫酸盐镀液使用寿命较短。本研究通过采用氮气对亚硫酸盐镀金液进行保护,减缓了使用过程中亚硫酸盐镀液的氧化速度、有效延长了镀液的使用寿命。To meet requirements of environmental protection,sulfite gold plating has been applied much more in thin film circuit processing in recent years.However,sulfite gold plating solution has bad stability,and fast increase of gold layer hardness,resulting in shorter service life of sulfite plating solution.The study protects sulfite gold plating solution with nitrogen,relieves oxidation rate of sulfite plating solution and prolongs service life of plating bath effectively.
