Description
Technical field
The present invention relates to electrolyte solution field, be specifically related to a kind of alkaline tin plating electrolytic solution.
Background technology
Zinc-plated and alloy is a kind of good weldability the coating with certain anti-corrosion capability, widespread use in electronic component, printed circuit board.The preparation of tin layer except the Physicals such as hot dipping, spraying, the methods such as plating, immersion plating and electroless plating because of simple in industrial widespread use.
Immersion plating is workpiece to be immersed to contain want to plate out in the solution of metal-salt, by chemical replacement principle, at workpiece surface, deposits metal plating.These are different from general electroless plating principle, because not containing reductive agent in its plating solution.Also different with contact plating, contact plating is must closely be connected with an active metal when workpiece immersion is wanted to plate out in metal salt solution, this active metal is that anode enters solution ejected electron, and the metal ion that in solution, current potential is higher obtains being deposited on workpiece surface after electronics.Immersion tin is only carried out on iron, copper, aluminium and alloy separately thereof.The reductive agent that copper or nickel self-catalyzed deposition are used all can not be used for reducing tin.The most simply explain it is because overpotential of hydrogen evolution is high on tin surfaces, and above-mentioned reductive agent is evolving hydrogen reaction, so tin ion can not be reduced to tin simple substance.Want chemical plating stannum just must select the strong reductant of another kind of not liberation of hydrogen, as Ti3+, V2+, Cr2+ etc., only have the report with T3+/Ti4+ system.Based on this, now study a kind of alkaline tin plating electrolytic solution, available insoluble anode, operating restraint are wide, formula is simple.
