Abstract
A method for manufacturing a solid electrolyte aluminum-electrolytic capacitor, includes: (1) welding a capacitor core of a capacitor onto an iron bar, applying a voltage for chemical treatment, and thereafter, washing and drying the capacitor core; (2) impregnating the dried capacitor core in a dispersion B for 1˜30 minutes; (3) removing the capacitor core, creating a vacuum and then impregnating the capacitor core in the dispersion B for 1˜10 minutes; (4) while in the dispersion B, breaking the vacuum and performing pressurization for 1˜10 minutes; (5) while in the dispersion B, performing depressurization to atmospheric pressure, for 1˜10 minutes; (6) placing the capacitor core in a temperature of 50˜100° C. and drying for 20˜60 minutes, and then in a temperature of 110˜200° C. and drying for 20˜60 minutes; (7) impregnating the dried capacitor core in a dispersion C for 1˜30 minutes; (8) placing the capacitor core in a temperature of 65˜100° C. and drying for 20˜60 minutes, and then in a temperature of 135˜165° C. and drying for 20˜60 minutes; and (9) Repeating steps (3) to (8) at least once.
