【摘要】 研究了利用镍/铜胶体活化的环氧树脂板的化学镀镍方法,给出了镀镍液的工艺配方:30g/LNiSO4·6H2O,10g/LCH3COONa,10g/LNaH2PO2·H2O,温度(80±2)℃,时间30min。探讨了用镍/铜胶体处理印制板时温度、时间和pH的影响,测定了化学镀镍层的剥离强度。实验结果表明,获得胶体溶液的pH为7.80,镍/铜胶体的粒径随酒石酸钠钾摩尔浓度的增加而减小,镀层的剥离强度为1.38kg/cm。更多还原

【Abstract】 The method of using nickel and copper colloids to activate the surface of epoxy resin was studied, and the formulation of nickel plating bath was given as follows: 30 g/L NiSO₄·6H₂O, 10 g/L CH₃COONa, 10 g/L NaH₂PO₂·H₂O, temperature of（80±2）℃, time of 30 min . The influences of temperature, time and pH on the process of PCB by using Ni/Cu colloid catalyst were discussed, and the peeling strength of nickel deposit was tested. The test results show that the pH value of colloid solution is 7.80, the particle diameter decreases with the increase of concentration of potassium sodium tartrate tetrahydrate, and the peeling strength of deposit is 1.38 kg/cm.更多还原
