Description
技术领域
本发明涉及电路板镀镍技术领域,尤其涉及一种在铝箔制作线路的电路板的焊盘做化学镀镍的工艺。
背景技术
一种铝箔材料电路板的化学镀镍工艺,所述电路板包含基板、绝缘胶、线路层、阻焊层、焊盘。
所述基板是铝板、玻璃纤维板、铜板等不可弯折的厚金属材料的可以做成硬质电路板(PCB),所述基板是PI、PET、PVC等可以弯折的塑料薄膜的可以做成软质电路板(FPC)。
所述电路板是经过以下工艺实现的:1,把铝板、玻璃纤维板、铜板等不可弯折的厚金属材料或者PI、PET、PVC等可以弯折的塑料薄膜与铝箔通过绝缘胶粘合在一起形成基板。2,在铝箔面做出线路形成线路层。3,在线路层覆盖油墨或者覆盖膜形成阻焊层。4,在线路层覆盖阻焊层时预留需要焊接元器件的区域形成焊盘。
通过以上步骤做出来的电路板的焊盘是不能通过普通的锡膏焊接的,因为铝在空气中氧化形成的氧化膜是拒焊的,所以我们通过在焊盘上化学镀镍来解决焊接问题。现行的化学镀镍工艺如下:除油(3-5min)-----2级水洗-----除垢(3-5min)-----2级水洗-----浸锌(2min)-----2级水洗-----硝酸退锌(2min)-----2级水洗-----二次浸锌(2min)-----2级水洗-----预镀碱性化学镍-----2级水洗-----化学镀镍(10-20min)-----2级水洗-----封孔(3-5min)-----2级水洗-----烘干。此工艺流程复杂,生产周期非常长,产能低下。
发明内容

为有效解决上述问题,本发明采取的技术方案如下:
一种铝箔材料电路板的化学镀镍工艺,包括以下步骤:

具体地,所述步骤3中,催化剂包括以下质量浓度的各组分:乳酸50-150g/L;缓蚀剂5-15g/L;氯化镍6-15g/L,OP乳化剂10-15g/L;乙醇10-20g/L,催化时间为1min,温度介于30-50℃之间,pH介于0-2之间。
具体地,所述缓蚀剂为钼酸钠。
具体地,所述步骤1中,碱蚀液包括以下质量浓度的各组分:NaOH 10-40g/L,Na2MoO4 10-40g/L,碱蚀的时间为1min。

具体地,步骤7中,封孔剂包括以下质量浓度的各组分:十八硫醇3-20g/L;苯并咪唑1-5g/L;OP乳化剂20-50g/L,封孔时间为1min。
本发明的有益效果:本发明的工艺中,碱蚀的作用是清洁铝线路表面的污物和氧化物,采用了催化剂催化,催化剂在铝表面上沉积了一层薄的化学镍,起到了钝化铝表面的作用,把空气与铝表面隔离起来,阻止了铝表面的氧化;水洗之后直接浸入化学镀镍的药水,在经过催化剂催化的铝表面沉积了一层薄的化学镍的上面再沉一层镍,增加镍的厚度至满足焊锡要求,这样就可以实现在铝表面的焊接,同时满足附着力的要求,最后通过封孔来保护化学镀镍防止氧化,本工艺从原来的17个步骤,简化到9个步骤,大大缩短了生产时间,提高了生产效率,降低了生产成本,节约了大量资源,同时省去了两次沉锌步骤及之间的硝酸退镀工艺,改善了操作环境,减少了排放,利于环保,一种铝箔材料电路板的化学镀镍工艺广泛应用于LED灯带、灯泡、灯管等电子产品,质量可靠、性能稳定,物美价廉。
