Printed Circuit Board Fabrication Tin Stripping

In reference to the stripping process, it is absolutely crucial that the tin is oxidized completely to the stannic (Sn ++++) form. Once the metal has been oxidized, it must then be dissolved into solution. Unfortunately, most stannic salts are insoluble in water. This includes the stannic oxide formed during the stripping reaction.
