  • Patent number: 8203848
    Abstract: Provided is a simplified structure of a circuit device in which a power element generating a large amount of heat is incorporated. The circuit device according to the present invention includes: a circuit board whose surface is covered with an insulating layer; a conductive pattern formed on the surface of the insulating layer; a circuit element electrically connected to the conductive pattern; and a lead connected to a pad formed of the conductive pattern. Furthermore, a power element is fixed to the top surface of a land portion formed of a part of the lead. Accordingly, the land portion serves as a heat sink, thereby contributing to heat dissipation.

  • Publication number: 20120018201
    Abstract: Provided are a circuit board easy to process by laser and a manufacturing method thereof A circuit board of the present invention includes a substrate, an insulating layer covering an upper surface of the substrate, and a conductive pattern of a predetermined shape formed on an upper surface of the insulating layer. The insulating layer is made of a resin material highly filled with a filler made of silica. Further, a colorant made of an inorganic material is added to the resin material. Accordingly, when a laser is radiated onto the insulating layer in order to perform cutting and removing processing, the insulating layer is removed because the laser is absorbed by the colored resin material.

    Abstract: Provided are: a light emitting module which has an improved heat-dissipating property and whose reflectance reduction is prevented. The light emitting module mainly includes: a metal substrate; a conductive pattern formed on the upper surface of the metal substrate; and a light emitting element disposed on the upper surface of the metal substrate and electrically connected to the conductive pattern. Furthermore, in the light emitting module, an insulating layer is removed in a region where the conductive pattern is not formed, but is left unremoved in a region right below (or covered with) the conductive pattern. In other words, in the region where the conductive pattern is not formed, the upper surface of the metal substrate is not covered with the conductive pattern, and a metal material constituting the metal substrate is exposed.
