Environment-friendly bright tin plating treatment technology method

The invention discloses an environment-friendly bright tin plating treatment technology method in the technical field of tin plating treatment process. Any cancerogenic substance and toxic aldehydes are not added into prepared electroplating bath, harm to a human body and pollution to environment are avoided, and the electroplating bath is pollution-free electroplating bath. All components of theelectroplating bath are good in dispersity. By means of the coordinative effect of all the components, hydrolysis of stannous ions and oxidation of the components like a brightening agent are effectively avoided, it is ensured that the sulfo-acid type semi-bright pure tin electroplating solution is clear and transparent, stability is high, when electroplating is carried out, deposition speed is high, and production efficiency is high. Moreover, within the wide current density range from a high section to a low section, crystallization in a tin electroplating layer is meticulous, the tin electroplating layer is uniform
