2）pH值——实践结果表明，镀镍电解液的pH值对镀层性能及电解液性能影响*。在pH≤2的强酸性电镀液中，没有金属镍的沉积，只是析出轻气。一般PCB镀镍电解液的pH值维持在3—4之间。pH值较高的镀镍液具有较高的分散力和较高的阴极电流效率。但是pH过高时，由于电镀过程中阴极不断地析出轻气，使阴极表面附近镀层pH值升高较快，当大于6时，将会有轻氧化镍胶体生成，造成氢气泡滞留，使镀层出现针孔。氢氧化镍在镀层中的夹杂，还会使镀层脆性增加。pH较低的镀镍液，阳极溶解较好，可以提高电解液中镍盐的含量，允许使用较高的电流密度，从而强化生。但是pH 过低，将使获得光亮镀层的温度范围变窄。加入碳酸镍或碱式碳酸镍，pH值增加；加入氨基磺酸或硫酸，pH值降低，在工作过程中每四小时检查调整一次pH值。
3）阳极——目前所能见到的PCb常规镀镍均采用可溶性阳极，用钛篮作为阳极内装镍角已当普遍。其优点是其阳极面积可做得足够大且不变化，阳极保养比较简单。钛篮应装入聚丙烯材料织成的阳极袋内防止阳极泥掉入镀液中。并应定期清洗和检查孔眼是否畅通。新的阳极袋在使用前，应在沸腾的水中浸泡。

1) 麻坑：麻坑是有机物污染的结果。大的麻坑通常说明有油污染。搅拌不良，就不能驱逐掉气泡，这就会形成麻坑。可以使用润湿剂来减小它的影响,我们通常把小的麻点叫针孔，前处理不良、有金属什质、硼酸含量太少、镀液温度太低都会产生针孔，镀液维护及工艺控制是关键，防针孔剂应用作工艺稳定剂来补加。
2) 粗糙、毛刺：粗糙就说明溶液脏，充分过滤就可纠正（pH太高易形成氢氧化物沉淀应加以控制）。电流密度太高、阳极泥及补加水不纯带入杂质，严重时都将产生粗糙及毛刺。
