ELECTROPLATING APPARATUS FOR PLANAR WORK PIECES, PARTICULARLY CIRCUIT BOARDS

摘要

An electroplating apparatus for plate-shaped workpieces which are conveyed in a horizontal path through an electrolytic cell characterized by the edges of the workpieces being grasped via contact elements that are secured on an endless circular flexible metal band. The side face of the metal band facing toward the workpiece glides above and below the conveyor and contact elements on guide and seal elements that extend in the wall of the cell along the horizontal direction. The metal band and conveyor and contact elements simultaneously have the job of conveying the workpiece, of cathodic contacting of the workpiece and of sealing an electroplating cell against the emergence of electrolyte solution.
