Title:
METHOD OF CONTINUOUSLY MONITORING THICKNESS OF OXIDE FORMED ON ALUMINUM FOIL FOR ELECTROLYTIC CONDENSER
Document Type and Number:
Japanese Patent JPS60253209
Kind Code:
A
Abstract:
Either after or during the process of forming aluminum foil for use in making electrolytic capacitors, the formed oxide foil is drawn through two separate electrolytes wherein two electrodes are immersed respectively. An AC voltage source is connected between the two electrodes. The resulting reactive current is a direct measure of the potential capacitance per unit foil area that can be obtained in capacitor manufacturing and is also an indirect measure of the oxide film thickness.
