ABSTRACT:
The present invention relates to a machine for the continuous gold-plating of contact tabs for printed circuit boards which comprises a plurality of cells aligned in sequence which perform the operations of stripping, nickel-plating and gold-plating, and also intermediate operations of rinsing and neutralization, and through which cells said printed circuit boards are conveyed by a double conveyor belt which also effects the cathodic electrical contact for each cells. The said cells are provided with one or more feed chambers and at least one collection tank, provision being made for a chemical or electrochemical bath cascade flow area between said feed chamber or chambers and said collection tank or tanks. Losses from the chemical or electrochemical baths are prevented by recovery chambers placed at the inlet and outlet of each cell.
