Electrode leading-out method and packaging method for tantalum electrolytic capacitor

Abstract

Disclosed is an electrode leading-out method and packaging method for a tantalum electrolytic capacitor. The electrode leading-out method includes the following steps: S1, fabricating an insulating protective layer outside an electrode body of the tantalum electrolytic capacitor; S2, exposing a cathode leading-out part on a cathode pre-leading-out part, and exposing a tantalum core leading-out end in an area where a terminal of a tantalum core is located; S3, depositing a metal layer on each of the cathode leading-out part and the tantalum core leading-out end which are exposed; and S4, fabricating an outer electrode for mounting on each of the metal layer of the cathode leading-out part and the metal layer of the tantalum core leading-out end so as to respectively lead out a cathode and an anode.
