    摘要: In order to electroplate workpieces comprising high-aspect ratio holes a method is disclosed comprising the steps bringing the workpiece and at least one anode into contact with a metal plating electrolyte, and applying a voltage between the workpiece and the anodes, to the effect that a current flow is provided to the workpiece. The current flow is a pulse reverse current flow having a frequency of at most about 6 Hertz. According to the frequency each cycle time comprises at least one forward current pulse and least one reverse current pulse.

    摘要: 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.
