Production manner of the solid-state electrolytic condenser, forming dielectric formation on the polymerization liquid adhesion

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a solid electrolytic capacitor having satisfactory uniformity in thickness and small variations in the characteristics.;SOLUTION: A liquid tank unit 100 is prepared where the unit has a liquid tank 26 and a pair of moving members 27. A polymerizing liquid P1 that becomes a solid polymer electrolyte layer is stored in the liquid tank 26. The pair of moving members 27 comes into contact with the liquid surface of the polymerizing liquid P1, and they can freely approach or separate to/from each other. When an element intermediate M1 dipped into the liquid tank 26 is pulled from an area between the pair of moving members 27, the pair of moving members 27 will be approaching closely, and the interval d2 becomes very narrow. As a result, the area of the liquid surface of the polymerizing liquid P1 between the pair of moving members 27 becomes small, and accordingly, the surface tension of the polymerizing liquid P1 between the pair of moving members 27 becomes large, and the surplus polymerizing liquid P1, adhering to the element intermediate M1 can be drawn back into the liquid tank 26 due to surface tension.;COPYRIGHT: (C)2008,JPO&INPIT
