Abstract
Jet electrolysis appts. for the deposition or removal of metal on workpieces which are at least partly conducting is claimed. The workpiece esp. a printed circuit board travels through a tank fitted with sealing lips at its inlet and outlet. In the tank are pairs of driven rollers through which the board travels, and also other rollers on which the board rests. Nozzle provide rectangular or other streams of electrolyte flowing in a direction at 90 degrees to the direction in which the board travels, and >=1 sliding contact is used which travels on a selected zone of the board or on an endless conducting grid carried by the board. Appts. is used esp. for mfg. printed circuit boards by photo-electrodeposition, where a row of tanks is used, the outlet contact on one tank forming the inlet contact for the next tank. Used in conjunction with photoresist e.g. to deposit Cu in holes in a board.
