Abstract

The invention discloses an aging method for a high specific volume aluminum electrolytic capacitor, which comprises a plurality of process steps of clamping, energizing and aging at normal temperature, ventilation in an aging room, high temperature aging and constant temperature aging. Through the air convection device set in the room temperature cold air aging box, the temperature of the air flowing in the room temperature aging room is reduced, so that the temperature of the aluminum electrolytic capacitor itself is lowered during the normal temperature electrification process, so that the voltage can be over-added and quickly rise to the value required by the product process, so that the voltage can be boosted. The time has been shortened from 6 to 8 hours to 3 to 4 hours. Use this method to shorten the aging time of aluminum electrolytic capacitors by 50%, thereby saving 50% of electricity, and the boosting time is short, the leakage current is small, the electrical performance is good, the production cost of the product is greatly reduced, and the input cost is greatly reduced.

Description

technical field [0001] The invention belongs to the industry of electronic components, and in particular relates to an aging method for high specific volume aluminum electrolytic capacitors. Background technique [0002] Electrolytic capacitors have electrolyte materials that store charges inside, which are divided into positive and negative polarities, similar to batteries, and cannot be reversed. The positive electrode is a metal substrate with an oxide film, and the negative electrode is connected to the electrolyte (solid and non-solid) through a metal plate. [0003] Nonpolar (bipolar) electrolytic capacitors adopt a double oxide film structure, which is similar to two polarized electrolytic capacitors connected by two negative electrodes. The two electrodes are two metal plates (both with oxide films) The two groups of oxide films are connected with electrolyte in the middle. Polar electrolytic capacitors are usually used in power circuits or intermediate frequency a...
