Tin plating species
Immersion tin plating
Immersion plating is to immerse the workpiece in the solution containing metal salt to be plated, according to the principle of
chemical replacement deposition of metal coating on the surface of the workpiece. This is different from the general electroless
plating principle, because its plating solution does not contain reducing agent. And contact plating is not the same, contact
plating is to dip the workpiece into a metal salt solution must be closely connected with an active metal, the active metal for
the anode into the solution to release electrons, higher potential in the solution of metal ions to get electrons deposited on the
surface of the workpiece. Dip tin plating is carried out only on iron, copper, aluminum and their respective alloys.
