摘　　要：研究了化学镀锡预镀溶液的组成和工艺条件对镀层厚度和表面形貌的影响。结果表明:预镀溶液的主盐和配位剂以及预镀时间对化学镀锡层的厚度影响较大;而镀锡层的表面随着添加剂的质量浓度的增加变得平整、致密。选择适宜的预镀液的酸度也可以提高镀层质量。The effects of the composition and technological conditions of electroless tin preplating bath on the thickness and morphology of the coatings are investigated. The results show that the main salt and complexing agent of the preplating bath and preplating time have a greater impact on the thickness of electroless tin coating and the tin coating will become level and compact with the increasing of mass concentration of additive, By selecting suitable acidity of preplating bath, the coating quality can also be improved.
