Mr. Yang is the owner of an electroplating factory in Suzhou, Jiangsu Province, which specializes in tinning various connectors and precision electronic components.In the past more than a month, the matte tinned workpiece produced by Mr. Yang has been subjected to a 250 ℃ wave soldering heat test, and the tin coating has appeared dark and bulging tin accumulation phenomenon,However, the additive supplier has not been able to solve this problem,So Mr. Yang wants to replace a matte tin plating additive that will not have tin accumulation.
One day, while searching on the Internet, Mr. Yang saw Bigolly's matte tin plating additive Sn-808 and the effect picture of the product. After that, he learned about the performance of this additive in detail, but he was still concerned about whether there would be tin accumulation in the production process.After understanding the production situation of Mr. Yang, the engineer explained to Mr. Yang that after the general matt tin workpiece is post-treated, it will not change color after the 250 ℃ wave soldering heat test.This phenomenon usually occurs because the matt tin plating additive is out of balance, or there are too many organic substances in the plating solution, and Mr. Yang has used carbon powder to treat the plating solution.When the tin coating of the plated part is passivated, it will produce non-wetting, and the tin can not be wetted after it is put on, and it will form bulging and spherical tin accumulation phenomenon.
This matte tin plating additive Sn-808 is produced with new R&D technology and imported raw materials from the United States.It can replace similar products of Rohm&Haas and Atotech. It has less organic decomposition in the production process, can reduce the treatment frequency of the plating solution, ensure that the tin coating of the workpiece is uniform and stable, and has good welding performance. After the wave peak welding heat test at 250 ℃, the coating will not have discoloration, sagging and other phenomena.After comparing other additives, Mr. Yang decided to buy a bucket of Sn-808 to try.
Mr. Yang used this matte tin plating additive Sn-808 under the guidance of the engineer. After the wave soldering heat test at 250 ℃, the tin coating of the workpiece will not change color, sagging and other phenomena, which greatly improves the production efficiency and has also been recognized by many customers.Soon Mr. Yang placed the order again and signed a cooperation agreement with Bigolly.
Therefore, when tin accumulation always occurs after the wave peak welding heat test of the tinned workpiece, try this matte tin plating additive Sn-808 as soon as possible.If you are interested in matte tin plating additives, please contact Bigolly customer service for free samples and detailed technical information!
