A process for preparing a solid electrolytic capacitor comprising application of coverage enhancing catalyst followed by application of a conducting polymer layer. Coverage enhancing catalyst is removed after coating and curing.

Materials and method for improving corner and edge coverage of solid electrolytic capacitors

An improved solid electrolytic capacitor and method of forming a solid electrolytic capacitor is described. The method includes forming an anode comprising a valve metal or conductive oxide of a valve metal wherein an anode lead extension protrudes from the anode. A dielectric is formed on the anode and a cathode layer is formed on the dielectric. The anode, dielectric, and cathode layer are encased in a non-conducting material and the anode lead extension is exposed outside of the encasement at a side surface. A conductive metal layer is adhered to the anode lead extension which allows termination preferably by electrically connecting a preformed solid metal terminal, most preferably an L shaped terminal, to the conductive metal layer at the side surface.

Solid electrolytic capacitor and method of manufacture

A process for preparing a solid electrolytic capacitor comprising application of coverage enhancing catalyst followed by application of a conducting polymer layer wherein the conductive polymeric cathode comprises the coverage enhancement catalyst wherein the conductive polymeric layer has improved coverage of the corners and edges. Coverage enhancing catalyst is removed after coating and curing.

Materials and methods for improving corner and edge coverage of solid electrolytic capacitors

A process for preparing a solid electrolytic capacitor comprising application of a non-ionic polyol prior to application of a conducting polymer layer.

Process for producing electrolytic capacitors and capacitors made thereby

A method for forming a capacitor including forming an anode from a valve metal; forming an oxide on the anode to form an anodized anode; dipping the anodized anode into a slurry of conductive polymer; drying the intrinsically conductive polymer; and providing external terminations in electrical contact with the anode and the conductive polymer.

High voltage solid electrolytic capacitors using conductive polymer slurries

An improved method for forming a capacitor. The method includes providing a carrier with a channel therein, providing a metal foil with a valve metal with a first dielectric on a first face of the metal foil, securing the metal foil into the channel with the first dielectric away from a channel floor, inserting an insulative material between the metal foil and each side wall of the channel, forming a cathode layer on the first dielectric between the insulative material, forming a conductive layer on the cathode layer and in electrical contact with the carrier, lap cutting the carrier parallel to the metal foil such that the valve metal is exposed, and dice cutting to form singulated capacitors.

Channel method for forming a capacitor

A method for maintaining quality of monomer during a coating process for intrinsically conductive polymer which suppresses unwanted by-products. A neutralization process using a base or anion exchange resin is used batch-wise or continuous.

Process for manufacturing low ESR conductive polymer based solid electrolytic capacitors

A capacitor and method for manufacturing the capacitor. The capacitor comprises an anode; a dielectric oxide layer coated on the anode and a plurality of conductive islands coated on the dielectric oxide layer. An organic conductive cathode is coated on the dielectric layer and conductive islands.
