Some customers inquired that in the production process of using matte tin additives, sometimes the plating in the low area of the workpiece is prone to leakage of plating, what is the reason for this?
Bigely Technology has analyzed the characteristics of Sn-808, a sulfuric acid matte tin additive, based on on-site experience and the product, and needs to pay attention to the following two points in the production process:
1, the content of matte tin additive Sn-808 in the plating solution is seriously insufficient. The role of additives in the plating solution is to provide the dispersing ability of the plating solution, and improve the cathodic polarization, refinement of crystallization, so that the workpiece to obtain good toughness and solderability performance of the tin layer. When the content of additives is very low, due to the poor dispersing ability of the plating solution, it will affect the normal deposition of the tin plating layer in the low area of the workpiece, resulting in a leakage of the plating phenomenon. Therefore, we should control the content of additives in the production process within the process range.
Therefore, we should pay attention to these two points in the production process of using matte tin additives, and adjust the content of each component in the plating solution in time within the process range, to avoid the phenomenon of leakage of the plating layer, and to reduce the occurrence of failures.
