Method for fabricating solid electrolytic capacitors

Abstract

The instant disclosure relates to an improved method for the production of solid electrolytic capacitor, comprising the following steps. First, provide an insulating substrate. Next, form a plurality of conducting gels including aluminum powder on the insulating substrate. Thirdly, execute a high- temperature sintering process to metalize the conducting gels to form a plurality of aluminum plates. Next, form a dielectric layer on every aluminum plate. Then form an isolation layer on every dielectric layer to define an anodic region and a cathodic region. Lastly, form a conductive layer on the dielectric layer of every cathodic region, thus defining a solid electrolytic capacitor unit.

What is claimed is: 
     
         1 . A method for improving fabrication of solid electrolytic capacitors comprising the steps of:
 providing an anodized foil and a cathodized foil; and   employing a winding process for winding a spacer between the anodized foil and the cathodized foil along with a plurality of lead electrodes to form a tubular core, in which the anodized foil is formed by a powder of aluminum formed onto a sheet of aluminum, dried, high temperature sintered to result with a porous aluminum sintered body and forming an oxidized film thereon.   
     
     
         2 . The method as recited in  claim 1 , wherein the anodized foil is formed by the powder of aluminum sprayed onto the sheet of aluminum, dried, high temperature sintered to result with the porous aluminum sintered body.
