Method and device for the electrolytic treatment of electrically conducting structures which are insulated from each other and positioned on the surface of electrically insulating film materials and use of the method

摘要

For electrolytic treatment of electrically mutually insulated, electrically conductive structures 4 on surfaces of electrically insulating foil material (Fo), is unloaded from a store 15′, 15″, transported on a conveying line through a treatment unit 1 and brought in contact with treatment fluid F1. During transportation, the material Fo is guided past at least one electrode arrangement, having at least one cathodically polarised electrode 6 and at least one anodically polarised electrode 7, both being brought in contact with the treatment fluid F1 and being connected to a current/voltage source 8. Current flows through the electrodes 6, 7 and the electrically conductive structures 4. The electrodes 6, 7 are screened from each other so that substantially no electric current is able to flow directly between oppositely polarised electrodes 6, 7. The material Fo is finally loaded back onto a store 15′, 15″.
