Description

Technical Field

[0002] During the production of horn-type aluminum electrolytic capacitors, the aging process involves charging and discharging the product to repair the oxide film, reduce leakage current, increase product life, and identify products with potential problems. Traditional aging racks for horn-type aluminum electrolytic capacitors use a one-to-one, constant current, and constant voltage aging mode, with one cement resistor corresponding to one capacitor. When a problem occurs with this product, the single capacitor begins to discharge, with the voltage and current being applied to its corresponding cement resistor. The circuit is disconnected, and the product stops charging and aging. Due to the small capacity and power of a single product, and the small current, the product cannot be directly exposed. There is no obvious difference in the appearance of this product, and it can easily flow into the next process and flow to the customer, causing quality problems.
