  • Patent number: 8885312
    Abstract: An ESD protection device includes a ceramic base material, a pair of opposed electrodes provided on a surface of or in the ceramic base material, and a discharge auxiliary electrode film arranged to connect the pair of opposed electrodes, wherein the discharge auxiliary electrode film is composed of a material containing, as its main constituents, metallic particles and glass covering the metallic particles. The discharge auxiliary electrode film is formed by providing an electrode paste containing glass-coated metallic particles that have an approximately 15% rate of increase in weight at about 400° C. for about 2 hours in air, a resin binder, and a solvent so as to connect the pair of opposed electrodes to each other, and then firing at a temperature of about 600° C. or more, higher than a softening point of glass of the glass-coated metallic particles, and not +200° C. higher than the softening point.

  • Publication number: 20100164125
    Abstract: A method of evaluating the flame retardancy of a sealing resin comprises a step of fusion cutting a heating element by causing the heating element to generate heat by the passage of electric current to a test sample of a molded body of the sealing resin including the heating element therein; a step of igniting the sealing resin by continuing the passage of electric current even after the heating element is fusion-cut; and a step of measuring voltage and/or current applied in a period from when the heating element is fusion-cut to the ignition of the sealing resin. The test sample is used in the method of evaluating the flame retardancy and provided with a heating wire; conducting terminals made of metal having an electric resistance lower than the heating wire and connected to both ends of the heating wire; and a sealing resin layer covering the outer periphery of the heating wire.
