【摘要】：对比了3种高温镍药水对电子连接器端子纯锡镀层和焊脚薄金层高温焊接变色的改善效果,从中选取了一种最佳的高温镍药水。量化评价了该高温镍药水与高速连续电镀中普通镍药水在电流密度、电流效率、沉积速率、分散能力、覆盖能力、金属杂质容忍度以及环保性能方面的差异及兼容性,表征了两种镍药水一起连续电镀生产时的抗干扰性与所得镀镍层的最佳膜厚比以及耐蚀性、延展性和结合力。
[Abstract]:The effect of three kinds of high temperature nickel solution on the discoloration of pure tin coating at the end of electronic connector and the thin gold layer of welding foot at high temperature was compared. The optimum high temperature nickel solution was selected. The current density, current efficiency, deposition rate, dispersing ability and covering capacity of the high temperature nickel solution and the ordinary nickel solution in high speed continuous electroplating were quantitatively evaluated. The difference and compatibility of tolerance of metal impurity and environmental protection properties were used to characterize the anti-interference and the optimum thickness ratio, corrosion resistance, ductility and adhesion of the nickel coating produced by two kinds of nickel solution electroplating together.
