1. a kind of manufacturing process of solid electrolyte/aluminum electrolytic capacitor, the manufacture method be included in cathode foil and anode foil itBetween intervention electrolytic paper and the process that is wound into core bag, be melted into reparing process, impregnation monomer and oxidant and heat polymerization to be formedThe process of polymer dielectric, installs Jiao Gai and enters aluminum hull process, burin-in process and testing, sorting process, it is characterised in that:

  • InstituteStating chemical conversion reparing process is:

    The core bag of coiling and molding is immersed chemical conversion repair process is carried out in aqueous forming liquid, while by core bagCathode foil be melted into power supply positive pole electrically connect, by the anode foil of core bag with chemical conversion power supply negative pole electrically connect, during chemical conversion, togetherWhen the cathode foil and anode foil of core bag are powered, the time of chemical conversion repair process is 25 ~ 90 minutes, and chemical conversion repair process is only enteredRow is once;

    The manufacturing process be additionally included in chemical conversion reparing process after, formed polymer dielectric process before, to core bag according toIn secondary carry out deionized water clean and dry process, wherein the resistivity of deionized water be not less than 5M Ω

    , water temperature be 20 DEG C~100℃



    Dry and carried out 1~3 hour at 110~150 DEG C of temperature;

    A diameter of below 13mm of the capacitor, is highly below 16mm.
