Embodiment 1

[0030] refer to figure 1 , the improved polymer solid electrolyte aluminum electrolytic capacitor of the present invention has a specification of 25V47μF and a production quantity of 4500. The steps of making it are as follows:

[0031] 1. Anodized aluminum foil with a VF value of 62V, cathode foil, and electrolytic paper are wound into a core pack 1 through a core wrap winding machine. The electrolytic paper is placed between the anodized aluminum foil and the cathode foil, and the cathode foil wraps the core after winding Pack 1, and then use high-temperature tape to surround and fix it tightly. The high-temperature tape is polyphenylene sulfide or polyimide tape;

[0032] 2. Install the rubber cover on the core package 1, and spot weld the anode guide pin of the core package 1 on the iron bar 2. To ensure the consistency of the welding height, connect the positive pole of the power supply to a stand, and the stand and the iron bar 2 are connected, the negative pole of the ...

Abstract

The invention relates to an improved method for manufacturing a solid electrolyte / aluminum electrolytic capacitor. The method comprises the following steps: 1, electrolytic papers between an anode formation aluminium foil and a cathode foil are reeled to form core bags, wherein the cathode foil faces outwards and wraps the electrolytic papers, a high-temperature rubber belt is used for clinging and fixing both in a ring manner, and sealing rubber covers are mounted on the core bags; 2, the core bags are immersed into formation liquid to be subjected to repair processing, and the repaired core bags are subjected to carbonization processing, wherein the step 2 is repeated about 2-10 times; 3; the core bags are immersed into the formation liquid again to be subjected to formation and repair processing; 4, the carbonized core bags are immersed into an oxide-film protection liquid and then are dried at the temperature of 50-150 DEG C; and 5, firstly, the core bags are respectively placed into monomers and oxidant for immersion and heating convergence, then the processed core bags are mounted in an aluminum shell and a sealing procedure is performed, and lastly, the produced products are subjected to ageing processing.

Description

technical field [0001] The invention relates to a manufacturing method of an electrolytic capacitor, in particular to an improved manufacturing method of a solid electrolyte aluminum electrolytic capacitor. Background technique [0002] Compared with ordinary liquid electrolytic capacitors, solid electrolytic capacitors have outstanding electrical properties, such as low equivalent series resistance (ESR), high ripple current resistance, long service life, and stable performance. With the continuous upgrading of electronic products and the continuous improvement of their functions and performance, the requirements for high-frequency characteristics of capacitors are getting higher and higher. People reduce the ESR of solid electrolytic capacitors in various ways to meet the high-frequency characteristics of capacitors. . [0003] In the manufacture of solid electrolyte aluminum electrolytic capacitors, due to the formation of polymers, a series of reactions are required. Th...
