Bath preparation

     Fill the plating tank with 50% pure water and slowly add the required sulfuric acid.

While stirring, add appropriate amount of stannous sulfate and stir until completely dissolved. Add water to make up the water level and cool to about 25 ℃.

Add proper amount of Sn-808 matte tin additive. At this time, the preparation of the plating solution is completed and can be used for production.


     The plating solution should be analyzed regularly and the sulfuric acid concentration of the tin metal box should be maintained according to the recommended amount. The consumption of Sn-808 matte tin additive is 100-200 ml/kA hour. Its consumption depends on different customer requirements, operating temperature, carry-out loss and workpiece shape. The addition amount can also be adjusted according to Hull cell analysis.
