The plate-shaped workpieces are conducted through a treatment cell containing a treatment bath. Vertical slots for the passage of the workpieces are provided in the end walls of the treatment cell. Paired rods or pipes arranged loosely in the treatment bath in a vertical alignment are allocated to the slots as seals. In order to also enable a treatment of thin, non-rigid workpieces, two vertically directed and preferably driven rollers for the guidance of the workpieces are arranged at the admission side outside the treatment cell and immediately preceding the seals.

Device for treating plate-shaped work pieces, especially printed-circuit boards

An electrolysis device for electrolytic deposition of a metal on at least one surface of the tape which has been precoated with a metal provides an electrolytic metal deposition band in which there is a first electrode for connection to a first voltage source. A tape drive is provided for moving the tape through the bath including first guide rollers defining a single loop for the tape through the bath. A second electrode is provided in the tape path and mounted to contact the tape above the entrance to the bath and over an area of the one metallized surface and is connected to a second source potential. Second guide rollers along the tape path downstream of the bath, including a second guide roller contact the metallized surface and is connected to a third source potential.
