The immersion tin plating process is a substitution plating process where the tin is plated on the surface and copper is driven into the plating solution according to the chemical equation Sn2+ + Cu> Cu2+ + Sn. As the tin plating builds up it begins to prevent the copper from transferring into solution and therefore the plating process is self-limiting. However it is possible to achieve a 1.2 micron
