Matte Tin Plating

sample of Matte Tin Plating

This plating is used for the mechanical sliding parts, as the soldering part for low cost electronic parts, and the cans for tinned food.
Tin plating is utilized as an inexpensive (not noble) material for electronic parts requiring solderability. However, because the surface of the tin-plating tends to grow whiskers, it is necessary to prevent whisker from growing. For example, the consideration about under plating and the addition of copper or silver or bismuth as alloy elements, furthermore the heat treatment should be considered.
Matte tin plating is difficult to grow whiskers, compared to the bright type. On the other hand, this plating is easy to produce tin oxide powder by sliding, we will require additional evaluation relating to its use.
Matte tin plating sometimes come out as a glossy surface by colliding with other product, due to the soft surface. We should have a discussion about the appearance.
