Abstract
A selective plating apparatus (20) for zone plating is comprised of a contained supply (22) of plating solution having an elongated avenue of escape or nozzle (32) and anode means (42) mounted along the length of the avenue of escape (32) at a spaced location therefrom such that the plating solution leaving the supply (22) is charged by the anode means (42). The apparatus (20) further includes means (80, 94) for guiding a workpiece (120) having a zone (128) to be selectively plated through the apparatus (20) such that the zone (128) is proximate the avenue of escape (32), the workpiece (120) comprising a cathode means. The apparatus (20) includes means for maintaining a desired rate of plating solution through the avenue of escape (32) whereby the solution wets the selected zone (128) of the workpiece (120) and deposits a layer of plating in the desired zone (128) on the surface of the workpiece as it passes through the apparatus (20). The apparatus (20) is preferably comprised of two such contained supplies (22, 52) of plating solution having the respective avenues of escape (32, 68) on opposite sides (130, 132) of the workpiece (120) thus depositing plating on the selected zone (128) on both sides of the workpiece simultaneously.
