Estimating the term…
A problem during electrolytic treatment of printed circuit boards having a very thin basic metallization is that the treatment yields irregular results in various regions on the surface of the printed circuit board. In overcoming this problem the invention provides a device for electrolytically treating an at least superficially electrically conducting work piece having at least two substantially opposing side edges. The device comprises current supply devices for the work piece, said current supply devices each comprising contact strips located on the opposing side edges which are capable of electrically contacting the work piece at the substantially opposing side edges.
A device for electrolytically treating an at least superficially electrically conducting work piece (1) having substantially opposing side edges (24), said device comprising current supply devices for the work piece, said current supply devices each comprising contact strips (5) for electrically contacting the work piece (1) at the substantially opposing side edges (24).
A method for electrolytically treating an at least superficially electrically conducting work piece, comprising electrically contacting the work piece (1) at substantially opposing side edges (24) through contact strips (5) serving as current supply devices.
