Non-electrolyte tantalum electrolytic capacitor positive and negative electrode patch welding process

Abstract

The invention provides a non-electrolyte tantalum electrolytic capacitor positive and negative electrode patch welding process. According to the process, a positive lead and a negative lead of the electrolytic capacitor are completely removed; and then the positive and negative patches are fixed on the positive and negative ends of the electrolytic capacitor through electrolytic capacitor plasma ball welding, electrolytic capacitor patch spot welding and electrolytic capacitor patch full welding, so that the non-electrolytic tantalum electrolytic capacitor with the positive and negative patchfixed structure is obtained. The fixed structure of the positive and negative patches is obtained by adopting the process disclosed by the invention, so that the contact area of the product and a circuit board is increased when the product is welded. The mechanical strength of the product in the use process is increased, and the use reliability of the product in the structure is ensured. Operationis convenient, the production efficiency can be greatly improved, and the product percent of pass is increased.

Description

technical field [0001] The invention belongs to the technical field of capacitor design and manufacture, and in particular relates to a non-electrolyte tantalum electrolytic capacitor positive and negative patch welding process. Background technique [0002] With the continuous development of electronic information equipment in the direction of miniaturization and digitalization, it is required that the volume of the current metal-encapsulated solid electrolyte tantalum capacitors is continuously reduced, the installation size is continuously reduced, and the product must be fixed conveniently and reliably to meet the needs of aviation, aerospace, communications, etc. The need for equipment miniaturization. [0003] In the pre-preparation process of the non-solid electrolyte tantalum electrolytic capacitor, it is necessary to install a sufficiently long lead wire on the anode and cathode ends of the non-solid electrolyte tantalum electrolytic capacitor, which are the positiv...

AI Technical Summary

Problems solved by technology

[0003] In the pre-preparation process of the non-solid electrolyte tantalum electrolytic capacitor, it is necessary to install a sufficiently long lead wire on the anode and cathode ends of the non-solid electrolyte tantalum electrolytic capacitor, which are the positive lead and the negative lead respectively, so that the non-solid electrolyte tantalum electrolytic capacitor The installation and fixing of parts such as the shell, anode tantalum core, cathode, plug, fixing washer, and insulator have increased the space required for product installation and brought great inconvenience to product fixing.
