以酒石酸钠钾为络合剂的常温化学镀铜液研制

常温化学镀铜溶液具有反应温度低、甲醛自我分解少、维护费用低等优点。为了寻找合适添加剂并确定各组份最佳含量,获得一种反应活性好,维护简单的沉铜液,文中通过设计七因素三水平正交实验的方法,综合研究了沉铜液中各组份对沉积速率、溶液稳定性、镀层外观的影响,确定了一种以酒石酸钠钾为络合剂,甲醛为还原剂,稳定性较好、沉积速率较高、镀层外观较好的常温化学镀铜配方。

Study of an electroless copper plating bath using potassium sodium tartrate as chleating agent

Electroless copper plating bath working at room temperature has the advantages of lower working temperature, lower decomposition rate of formaldehyde and lower cost for maintenance. In order to obtain good copper layer, different additives must be added to the copper plating bath. A perpendicular experiment with seven factors and three levels was done to select suitable additives and determine the content of each composite. The influence of the different content of each composite on the deposition rate, the...
