Tin electroplating | Galvano Hengelo

Tin electroplating of metal

Do your components require tin electroplating? You can rely on Galvano Hengelo’s expertise, high processing capacity and short delivery times. In the electrical and electronic industry, tin electroplating is widely used as contact material.


Good solderability, ductility and corrosion resistance

Tin provides good solderability, ductility and corrosion resistance on contacts and components. However, the corrosion resistance depends on the porosity of the coating. It cannot provide a great level of corrosion resistance on steel because base metal corrosion can occur almost immediately in a pore as a result of the potential difference with the base. On copper (alloys), tin is extremely suitable as protection against oxidation. The copper maintains the high electrical properties and solderability.


Tin electroplating of brass

In the case of tin electroplating of brass, the solderability will deteriorate over time. This is due to the diffusion of zinc in the tin layer. To counteract this effect, a barrier of 2 to 3 microns of nickel must be applied under the tin for fine and/or critical contacts with brass.
