Tin plating brighteners are chemical substances added to the tin plating solution to improve the appearance and quality of the plated layer. Their effect on the solderability of the tin-plated layer is mainly reflected in the following aspects:
1. Improve the smoothness of the surface of the plating: tin plating brightener can reduce the roughness of the surface of the plating, so that the surface is smoother, which helps the flow and wetting of the solder, and thus can improve the soldering performance of the plating.
2. Reduction of surface defects: Tin plating brighteners can help to reduce possible defects in the plating such as porosity, craters, cracks, etc., which are generally not conducive to soldering, and the reduction can improve soldering results.
3. Affects plating organization: Tin plating brighteners may affect the size and distribution of tin grains, and a finer, more uniform grain structure usually facilitates improved metal flow and joining properties during soldering.
4. Effect on oxidation resistance of the plating: Some tin plating brighteners may make the plating more resistant to oxidation and enhance the wetting of the plating by the solder during the soldering process, but on the other hand, some brightener residues may also form an insulating layer that reduces oxidation resistance and soldering effectiveness.
