MG Chemicals Tin Electroplating Kit The Tin Electroplating Kit from MG Chemicals includes an electroplating tank that holds two gallons of plating solution, a tin anode set containing eight tin bar anodes with hooks, and ready-to-use tin electroplating solution. MG Chemicals' Tin Electroplating system is ideal for use in etch resisting, where the plating resist will be washed off and the board placed in sodium persulfate solution, which will remove all copper not protected by tin.
