环保型铝上镀铜的典型工艺全套.docx
环保型铝上镀铜的典型工艺-:铝上镀铜的典型工艺（传统工艺）1 .脱脂.2 .浸泡干净。3 .彻底冲洗。4 .浸入50%的硝酸溶液中。根据铝合金的不同,氟化钠、硫酸或铝酸可能必须与硝酸结合使用。5 .彻底冲洗。6 .浸入锌酸盐浴中1分钟.（专有的锌酸盐溶液是最好的）7 .使用50%硝酸去除镀锌层8 .彻底冲洗。9 .再次浸入锌酸盐溶液中。*10 .彻底中洗。11 .使用氟化物或非氧化物碱性冲击浴进行铜冲击。12 .彻底中洗。13 .在铜电镀槽中进行电镀。14 .镀铜后处理*双锌酸盐始终是获得铝基材料良好附着力的推荐程序。二：环保型铝上宜妾镀铜的典型工艺1.脱脂.2 .浸泡干净.3 .彻底冲洗.4 .浸入50%的硝酸溶液中。根据铝合金的不同，氟化钠、硫酸或铝酸可能必须与硝酸结合使用。5 .彻底冲洗.6 .在铜电镀槽中进行电镀。CuSO5HO.20-25g1.DW-O35D直接镀铜添加剂：60g1.PH2.0.t=5-15min温度：室温电流密度：1.-3Adm27 .镀铜后处理三适用范围铝及铝合金，镁合金，锌合金等直接电镀铜Typica1.processofcopperp1.atingonenvironmenta1.1.yfriend1.ya1.uminum1:Typica1.processofcopperp1.atingona1.uminum(traditiona1.process)1.
