Abstract

The invention discloses a manufacturing method for a solid electrolyte aluminum electrolytic capacitor, which includes the following steps: 1 electrolytic paper is placed between an anode formation aluminum foil and a cathode formation aluminum foil to be wound into a core bag, the cathode foil faces outwards and wraps up the electrolytic paper, and high-temperature adhesive tape is then used for surrounding and fastening in adhesive mode; 2 an adhesive cover used for sealing is installed on the core bag; 3 the core bag is immersed into formation liquid for formation repair treatment; 4 the formation repair treated core bag is carbonated; 5 step 3 and step 4 are repeated two to ten times; 6 the core bag is immersed into the formation liquid again for the formation repair treatment; and the core bag is respectively placed in a monomer and an oxidizing agent to be impregnated, and then heated, polymerized, filled in an aluminum shell, sealed and produced to be a product after aging treatment. A polymer solid capacitor produced by using the manufacturing method has the advantages of being good in characteristics in terms of capacity, loss, leakage current and series equivalence resistance and being long in service life. Therefore, the product has the advantages of being small in performance dispersion ratio and high in acceptability.

Description

technical field [0001] The invention relates to a manufacturing method of an electrolytic capacitor, in particular to a 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] Moreover, there are generally problems of poor product consistency and low pass rate in the solid electrolytic capacitor industry. Contents of the inventi...
