    缓冲剂──硼酸用来作为缓冲剂,使镀镍液的pH值维持在一定的范围内。实践证明,当镀镍液的pH值过低,将使阴极电流效率下降;而pH值过高时,由于H2的不断析,使紧靠阴极表附近液层的pH值迅速升高,导致
    Ni(OH)2胶体的生成,而Ni(OH)2在镀层中的夹杂,使镀层脆性增加,同时Ni(OH)胶体在电极表面的吸附,还会造成氢气泡在电极表面的滞留,使镀层孔隙率增加。硼酸不仅有pH缓冲作用,而且他可提高阴极极化,从而改善镀液性能,减少在高电流密度下的“烧焦”现象。硼酸的存在还有利于改善镀层的机械性能。

    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。

    6、GUZHANGYUANYINYUPAICHU

    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。
