Abstract
For electrolytic treatment of circuit boards and foils LP, a method and a device are used in which the sheets and foils are transported through a treatment unit and brought thereby in contact with treatment fluid. The sheets and foils are guided during transportation past at least one electrode arrangement, which comprises respectively cathodically polarized electrodesand anodically polarized electrodes, the cathodically and anodically polarized electrodes also being brought in contact with the treatment fluid. The cathodically polarized electrodes and the anodically polarized electrodes are connected to a current/voltage source, so that a current flows through the electrodesand the electrically conductive surfaces
