Removal of chemical conversion film (Ta2O5) during chemical conversion process of tantalum capacitor

摘要

The present invention relates to a process for producing a tantalum electrolytic capacitor, and more particularly to a process for producing a tantalum electrolytic capacitor,₂O₅) Is inevitably formed, which causes the main three characteristics of the tantalum capacitor to be deteriorated. Conventionally, such a chemical film is removed by manual operation, thereby increasing defective products and decreasing productivity due to welding defect. Accordingly, it is an object of the present invention to provide a lead wire film remover and a removing method thereof for improving the weldability of a tantalum capacitor, thereby improving three characteristics of the capacitor, reducing defective products, and increasing productivity.
