Process for the manufacture of a capacitor of the tantalum a solid electrolyte without wire or ribbon of the output, a device adapted to implement, and the capacitor thus obtained.

摘要

Method of manufacture of a capacitor tantalum and solid electrolyte, of the type without a wire or ribbon, in which a porous body 2 of tantalum is extended on one face 3 by a rod of tantalum 6, it forms a dielectric layer 7 is deposited a layer 9 of a solid electrolyte on the body and on a part of the rod, and it is deposited a layer 10 of the other hand, - electrode on a part of this layer of solid electrolyte, it covers the porous body in a sleeve 11 made of electrically insulating material leaving exposed a portion of the counter - electrode and the conductive layers, terminal 12 - 13, 14 - 15 insulated from one another, respectively in contact with the rod 6 and the - electrode 10, characterized in that it is formed by molding the sleeve 11 by masking the said portion of the layer of against - electrode 10 so as to prevent any overlap. Preferably, the rod is cut off at the level of the sleeve and by its edge 6a an electrical contact with the associated electrical terminal 12 - 13. & br / (see appended drawing in bopi) & br / & & br /
