Mr. Wu is the owner of an electroplating processing factory in Wenzhou, Zhejiang. His production line mainly focuses on the processing and production of semiconductor material bright tin plating process. Recently, Mr. Wu's tin plated workpieces have always had black spots, and the problem persists even after the supplier handles the plating solution, resulting in multiple customer complaints about the workpieces. So Mr. Wu wanted to replace it with an Acid tin plating brightener that wouldn't have black spots.
Mr. Wu searched online and found Bigley Technology's Bright acid tin plating additives Sn-807, and gained a detailed understanding of its characteristics. Mr. Wu consulted with the engineer again about the reasons for the black spots appearing after the workpiece is tinned. The engineer patiently explained to Mr. Li that some tinning glosses on the market have technical defects. During the use of the plating solution, the glosses will gradually decompose. After these decomposition products accumulate to a certain extent, the plating solution is prone to turbidity, and the coating is prone to brittleness, black spots, and other problems.
By using this Bright acid tin plating additives Sn-807, the plating solution has excellent stability, ensuring a uniform and bright appearance of the workpiece. Moreover, there are few decomposition products of the gloss agent, and the plating solution can remain clear even after long-term use. Therefore, the workpiece coating is not prone to brittleness, black spots, and other issues. So Mr. Wu planned to purchase a small amount of Acid tin plating brightener Sn-807 and give it a try.
After using this Bright acid tin plating additives, Mr. Wu found that the stability of the plating solution was really good, and there were no black spots on the coating. In this way, the production efficiency can be increased by 10-15%, effectively saving production costs. So Mr. Wu signed a long-term cooperation purchase and sales contract with Bigley.
So, when we use the sulfate tin plating process, when black spots are prone to appear on the workpiece coating, we might as well try Bigley's Acid tin plating brightener Sn-807. If you also want to find such a stable acidic tin plating gloss agent, you can contact Bigley customer service to obtain free samples and detailed technical information!
