  • Spray coating of cathode onto solid electrolyte capacitors
    Publication number: 20060157821
    Abstract: A process for forming a capacitor. The process includes the steps of forming an anode of a valve metal. A dielectric layer is formed on the valve metal. A conducting layer is formed on the dielectric layer wherein the conducting layer is the cathode. A carbon layer is sprayed onto the conducting layer and a silver layer is sprayed onto the on the conducting layer.
    Type: Application

  • Minimum volume oven for producing uniform pyrolytic oxide coatings on capacitor anodes
    Publication number: 20050056221
    Abstract: A pyrolysis oven provides uniform pyrolytic coatings on capacitor anodes. An oven chamber contains cross-flow blowers situated to provide uniform laminar flow of oven atmosphere over the objects to be treated. The top and side walls of the chamber meet in an inverted V such that when the blower operate, a vortex is created in the inverted V in the chamber.
