What is tin plating?
Tin plating provides a soft, ductile and corrosion resistant surface of pure tin metal. It is often used in electronic applications for its solderability and conductivity. Tin is generally considered non-toxic and non-carcinogenic and as such its use is generally approved for food contact applications. Matte finish tin plating is best for surfaces to be soldered due to the low organic content of the deposit. Bright finish tin plating offers a smoother, more reflective surface. This is accomplished with the use of organic brightening agents which may be less desirable when soldering.
