Abstract

The invention discloses a method for manufacturing an ultrathin high-temperature-resistant solid-state capacitor, which comprises the following steps of: nailing a guide pin on an anode aluminum foil and a cathode aluminum foil, separating by using an isolating layer, winding to form a capacitor core, sleeving a rubber plug subjected to surface treatment, performing formation repair and drying on the core, and then forming a conductive polymer in the core, thereby obtaining the ultrathin high-temperature-resistant solid-state capacitor. And finally, aging and sorting are carried out, so that the high-temperature-resistant solid-state capacitor can be obtained. The treated rubber plug is formed by coating or covering a protective layer on the surface of the rubber plug. According to the technical scheme, the temperature resistance of the rubber plug can be effectively improved, so that the solid electrolytic capacitor with excellent high temperature resistance is obtained.

Description

technical field [0001] The invention belongs to the technical field of solid aluminum electrolytic capacitors, and in particular relates to a manufacturing method of an ultra-thin high temperature resistant solid capacitor. Background technique [0002] With the popularization of mobile communications and the development of cloud services around the world, servers for wireless communication base stations and data centers are required to have large-capacity and high-speed performance; General components including capacitors are required to have high temperature resistance and long life performance, which is a huge challenge for ultra-thin solid-state capacitors. Due to the height limit requirements of ultra-thin solid-state capacitors, the design of capacitors can only be used with thinner thicknesses. For thin rubber plugs, if the ultra-thin capacitors are exposed to a high temperature environment for a long time, the rubber plugs are prone to cracking or lose their elastici...
