1.3 Synthetic Route


Application of stannous methanesulfonate
Electroplating is an important link in the production of printed circuit boards in the electronics industry. The quality of the coating directly affects the quality of printed circuit boards. At present, domestic lead and tin electroplating mainly adopts fluoroborate electroplating solution. This fluorine-containing and lead-containing process seriously endangers the health of operators and pollutes the environment. Methanesulfonate series products can not only eliminate fluorine and lead pollution, but also improve the performance of the coating.
