Method and apparatus for electroplating

A method and apparatus for quality high speed electrical plating of one or both sides of a metallic workpiece 12 wherein a combined consumable-non-consumable anode system so provides a uniformity of metallic deposition at relatively high speeds irrespective of the consumable anode 15 contour. A meta...

Zusammenfassung:A method and apparatus for quality high speed electrical plating of one or both sides of a metallic workpiece 12 wherein a combined consumable-non-consumable anode system so provides a uniformity of metallic deposition at relatively high speeds irrespective of the consumable anode 15 contour. A metal ion containing plating solution flows into contact with a workpiece through apertures 86 in the non-consumable anode 16 while metal ion concentration is maintained. The consumable-non-consumable anode system is used in a vertical or horizontal submerged cell configuration.
