Tin plating

Tin plating is a process in surface technology in which a layer of tin is applied to metallic surfaces. This process serves various purposes, including protection against corrosion, improving solderability and modifying electrical properties. During the tinning process, the metal to be tinned, often copper or steel, is immersed in a liquid tin bath or coated with molten tin. Chemical reactions between the tin and the metal create an even layer of tin on the surface. This protective coating provides a barrier against environmental influences and thus prevents the formation of corrosion on the underlying metal.

Tin plating also has the advantage of improving the solderability of the treated surface. Tin forms a good solder connection with many other metals, which is why tin plating is particularly widespread in the electronics industry. The tin layer ensures a uniform and reliable connection between electronic components and printed circuit boards. Another area of application for tin plating is in the food industry, particularly in the manufacture of food cans. Tinning the inner surface of the can ensures that the packaged food does not come into contact with the underlying metal, which improves the shelf life and quality of the product.

Tin plating is a proven process for improving the material properties of metal surfaces and is used in various industries. Its many benefits, from corrosion protection and solderability to food safety, make tinning an important step in the production and surface treatment of metal components.
