Title:
METHOD FOR MANUFACTURING ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2002/052593
Kind Code:
A1
Abstract:
A method for manufacturing an electrolytic capacitor using niobium as the material of an anode thereof, characterized in that in the step of forming a chemical coating on the anode, a liquid reaction mixture has a temperature which is not lower than the solidification temperature of the liquid mixture and is about 40 °C or lower (preferably, about 25 ° C or lower). The method can be used for manufacturing such a capacitor which is reduced in the change of its electrostatic capacity caused by a heat to the extent of that loaded by soldering reflow and is improved in the dependency of its electrostatic capacity on a bias voltage.
