Mr. Zhang from Xiamen, Fujian, has built a new electroplating production line to prepare for the production and processing of tin plating for electronic components.However, Mr. Zhang used the acid tin plating brightener to prepare the bath after new preparation. Although the coating color of the workpiece was uniform after tin plating according to the process parameters, the brightness was relatively poor, and the addition of brightener did not improve.What causes this?
According to field experience and the characteristics of acid tin plating brightener Sn-807, Bigolly engineers checked the process flow and plating solution of the production line, and found no problems.When the engineer asked the operator about the process of preparing the plating solution, he found that Mr. Zhang's production line used tap water, so he suggested that Mr. Zhang use pure water to prepare the plating solution.The reason is that there are still many impurities in the water quality of tap water to a certain extent, which are easy to bring in harmful impurities such as copper, iron, arsenic and antimony, and are not suitable for the tin plating requirements of workpieces with high coating requirements.
After Mr. Zhang used pure water to re prepare the plating solution, the tin coating of the workpiece was uniform and bright, and maintained good ductility and weldability.Although the use of pure water will increase the production cost, the plating solution has less impurities and high stability, which can improve the quality of the workpiece and reduce the failure rate.
Therefore, we are using the bath newly prepared with acid tin plating brightener, and the coating brightness of the workpiece after tin plating is poor, which may be the cause of water quality. Pure water should be used to prepare the bath to reduce the occurrence of failures.If you are interested in acid tin plating brightener, you can contact the Bigolly customer service for free samples and detailed technical information!
