  • Patent number: 5972246
    Abstract: Provided are an electro-conductive composition improved on its wettability and handled with ease and an electronic equipment using the same. The electro-conductive composition comprises: 28 to 45 wt % metallic particles X to form an alloy with a solder at a soldering temperature and to increase a melting point of the solder to a temperature higher than the soldering temperature; 30 to 60 wt % metallic particles Y hard to form an alloy with the solder at the soldering temperature, wherein the sum of contents of the metallic particles X and Y is in the range of 75 to 93 wt %; and the rest of a resin.
    Type: Grant

  • Patent number: 5948320
    Abstract: Provided are an electro-conductive composition improved on its wettability and handled with ease and an electronic equipment using the same. The electro-conductive composition comprises: 28 to 45 wt % first metallic particles easy to form an alloy with a solder; 25 to 60 wt % second metallic particles hard to diffuse into the solder; 3 to 7 wt % an oxide having a property to block penetration of the solder; and 7 to 30 wt % a resin.

  • Patent number: 4750084
    Abstract: A ceramic laminated capacitor having an approximately cylindrical external configuration. Dielectric layers and inner electrode layers are laminated, and the inner electrode layers are connected to outer electrodes to unite them into one body. A pair of insulators having a vertical section of a segment are bonded to the opposing end surfaces of the dielectric layers such that the convex surfaces of the insulators face outward.
