Title:
MANUFACTURING METHOD FOR AN ALUMINUM ELECTRODE PLATE FOR ELECTROLYTIC CAPACITOR AND MANUFACTURING APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2010/131290
Kind Code:
A1
Abstract:
Provided are a method and an apparatus for manufacturing an aluminum electrode plate for an electrolytic capacitor which can provide a simpler configuration of the apparatus and can stably etch between any of the electrodes, wherein three or more electrodes (20) are arranged opposite each other in an etching fluid (40). In addition, for three or more electrodes (20), an aluminum plate (10) is positioned between each pair of opposing electrodes (20). Then, an AC current is applied between the electrodes (20a, 20e) positioned at both ends of the three or more electrodes (20), and both sides of the aluminum plates (10) are etched. At this time, the AC current is not applied to the other electrodes (20b, 20c, 20d).
