ABSTRACT:
A tin electrolytic plating solution comprises a suitably selected nonionic surfactant having a branched alkyl group. The nonionic surfactant is contained either alone, or with a suitably selected cationic surfactant and/or a suitably selected alkyl imidazole. The invention also provides a tin electrolytic plating method using such a tin electrolytic plating solution, and a tin electroplated electronic part obtained by such a method.
