The tin plating additives used in the sulfate matte tin plating process have a direct impact on the quality of the plated layer, and the plated layer scratching is often related to the use and regulation of these additives. The type of additives, their concentration and their ratio in the plating solution will affect the final quality of the plated layer.
The following are some of the additive-related factors that can cause the plating to scratching:
1. Inappropriate concentration of matte tin additives: If the concentration of tin plating additives is too high or too low, it may affect the appearance and properties of the plated layer. High concentrations may result in excessive brightening effects, while low concentrations may not provide sufficient stability and brilliance.
2. Accumulation of matte tin additive decomposition products: In the plating process, some additives may gradually decompose, and the accumulation of their products to a certain extent may damage the quality of the plated layer.
3. Matte tin additive update frequency is not enough: in the plating process, additives will be depleted, if not replenished in a timely manner, will lead to a decline in the performance of the plating solution.
4. Imbalanced composition of matte tin additives: The tin plating process uses a variety of additives, such as brighteners, carriers, stabilizers, etc., which must be maintained in proper proportions. If the composition ratio is out of balance, it may lead to uneven appearance and performance of the coating.
5. Reaction of matte tin additives with contaminants: Contaminants present in the plating solution may react with the additives to form unwanted compounds, which can directly affect the quality of the plated layer and cause blooming.
In order to prevent the problem of plating layer scratching, electroplating plant needs to choose the right matte tin additives, Bigely matte tin additives Sn-808, after adding it to the solution, not only to get the plating layer white, smooth and dense, but also good weldability, can be widely used in the field of PCB and electronic components of tin plating.
