In the electroplating industry, tin plating of the surface of copper rows is a common process used to enhance the corrosion and oxidation resistance of copper rows. However, when using tin plating brightener, white haze sometimes appears on the surface of copper rows, which not only affects the aesthetics of the plated layer, but also may affect the physical and chemical properties of the plated layer. As a R&D and sales engineer of tin plating brightener, I will analyze the causes of this phenomenon in detail and introduce why the use of Bigely tin plating brightener Sn-807 can effectively reduce the failure of white haze of tin plating layer.
The imbalance of the tin salt concentration in the plating solution, the proportion of additives and the pH value and other parameters is one of the main reasons for the white haze of the tin plating layer of copper platings. Excessive concentration of tin salts in the plating solution may lead to rough crystallization of the plated layer and whitish phenomenon. Similarly, when the tin plating brightener is insufficient, the luster of the plated layer will be reduced and white haze is also prone to occur.
The components in Bigely tin plating brightener Sn-807 effectively inhibit the whitening of the plated layer and improve the brightness and uniformity of the plated layer. Sn-807 brightener ensures the stability of the plating solution and avoids side reactions such as cathodic hydrogen precipitation, thus improving the quality of the plated layer.
