Patent number: 6454817Abstract: Disclosed is a method for manufacturing a solid electrolytic capacitor using a functional polymer composition. The method comprises immersing the rolled aluminum electrolytic capacitor device in polyaniline solution with high electric conductivity to impregnate the device with polyaniline, drying the impregnated device in a drying oven which is maintained at constant temperature to fully remove the solvent, inserting the dried device to a capacitor aluminum can and then sealing with epoxy resin, to manufacture a solid electrolytic capacitor using a functional polymer. As such, the impregnation can be performed well at not only normal temperature and pressure, but also high temperature and reduced pressure. The solid electrolytic capacitor has the advantages of high capacity, low impedance and low ESR, and also, low manufacturing cost, simple processes and high reliability.Type: GrantFiled: May 22, 2001Date of Patent: September 24, 2002Assignee: Samwha Electric Co., Ltd.Inventors: Dal-Woo Shin, Jong-Joo Park, Young-Hoon Lee, Yong-Chul Kim, Sung-Ho Kim
