  • Patent number: 9024446
    Abstract: Conventional printed circuit boards had a problem of being inferior in heat-radiation characteristic, and metal-core printed circuit boards adopted to improve the heat-radiation characteristic had problems in having low rigidity and a tendency to bend. The ductility of the metal can be obstructed, and the metal protected; by covering substantially the whole area of the front and back sides of the metal core, consisting of metal as the main material, with a first ceramic film and a second ceramic film that obstruct the ductility of the aforementioned metal-core; and covering each of the ceramic films with insulated resin films, to cover the fragility of these ceramics.

  • Patent number: 8814029
    Abstract: The gap between first and second bonding portions is filled with a disperse solution obtained by dispersing copper micro-particles into a solution for copper oxide elution, so as to elute copper oxide configured as the outermost layer of the first bonding portion and copper oxide configured as the outermost layer of the second bonding portion, and copper oxide formed on the surface of each copper micro-particle. Pressure is applied to the first and second bonding portions using a press machine so as to raise the pressure of the disperse solution. At the same time, heat is applied under a relatively low temperature condition of 200° C. to 300° C., so as to remove the components contained in the disperse solution except for copper, thereby depositing copper. Thus, a first base portion and a second base portion are bonded via a copper bonded portion containing copper derived from the copper micro-particles.
