ABSTRACT:
A method of plating is shown in which a pair of counter-rotating rollers are positioned above an electrolyte tank and a printed circuit board inserted therebetween in electroplating relationship. Metering rollers are provided at opposed stations outboard of the plating rollers to express electrolyte therefrom, preferably in yieldable relationship with the plating rollers. Masking rollers are provided directly above the plating rollers, and a film is rolled on the masking rollers for lowering into the position between the plating rollers to thereby mask the surface being plated and control the amount of plating. The unit is provided with a dust cover having an insert slot in a medial portion. The method contemplates the plating of, or removal of metal from, members which are capable of being positioned between a pair of opposed rotating rollers. The method also relates to the utilization of film-like members for masking the area which is plated or from which metal is removed. Light wiping contact with the surface to be plated by an electrolytic carrying material on the rollers is also shown.
