    Abstract: The present invention provides a printed circuit board, which includes a dielectric substrate having via holes formed in the thickness direction, and a conductor including a conductive filler is filled in the via holes. The dielectric substrate has patterned wiring layers on both surfaces, and the wiring layers are connected electrically with each other by the conductor. The dielectric substrate is made of a glass cloth or a glass nonwoven fabric impregnated with a thermosetting epoxy resin mixed with fine particles, and the conductive filler in the conductor has an average particle diameter larger than that of the fine particles. Accordingly, the printed circuit board has an improved moisture resistance as a whole and also excellent connection reliability and repair resistance. In addition, the dielectric substrate of the printed circuit board has an improved mechanical strength such as flexural rigidity. The present invention also provides a method of manufacturing such a printed circuit board.

    Abstract: A capacitor sheet includes a laminate sheet, interface-connection feedthrough conductors for electrically connecting faces of the laminate sheet, and capacitor-connection feedthrough conductors. The laminate sheet has at least one laminate which is composed of a power source layer electrode, a grounding layer electrode, and a dielectric layer interposed between the power source layer electrode and the grounding layer electrode. The interface-connection feedthrough conductors are formed in through holes that pass through the dielectric layer, the power source layer electrode, and the grounding layer electrode, and are insulated by insulation walls from the power source layer electrode and the grounding layer electrode provided inside. The capacitor-connection feedthrough conductors are formed in regions where only either the power source layer electrode or the grounding layer electrode is provided, and are connected electrically with either the power source layer electrode or the grounding layer electrode. This configuration makes the electric connection for employing the capacitors and the electric connection between faces of the sheet independent from each other. Thus, it is possible to provide a capacitor sheet in which the adverse effects of inductances of vias are minimized.

    Abstract: A circuit board is configured so as to include not less than two wiring layers, an insulator layer for electric insulation between the wiring layers, and an inner-via-hole conductive member provided in the insulator layer in a thickness direction of the insulator layer, for electric connection between the wiring layers. The insulator layer is made of a composite material containing an organic resin and a material having a smaller thermal expansion coefficient than that of the organic resin, and includes a surface part, a core part, and a surface part laminated in the stated order, the surface part having a high content of the organic resin, the core part having a low content of the organic resin. The wiring layers have a land portion that is connected with the inner-via-hole conductive member, the land portion being embedded so as to be substantially in contact with the core part, and the inner-via-hole conductive member has a thickness substantially equal to a thickness of the core part. According to this configuration, a part of the metal foil is embedded in the insulator layer so as to be in contact with the core layer. Therefore, this makes it possible to provide a circuit board in which portions of the conductive material can be selectively compressed, and which hence is capable of ensuring stable connection between layers.

    Abstract: A circuit board including a desired number of electrically insulating layers and wiring layers laminated alternately, and an inner via hole for securing an electrical connection between the wiring layers by compressing and hardening a conductive paste including a conductive particle and a resin. In the electrically insulating layer, a porous sheet is provided a resin sheet at least one surface, and the porous sheet is not impregnated with a resin at least at a central portion. A through hole penetrating the electrically insulating layer in the direction of the thickness of the electrically insulating layer is filled with a conductive paste including a conductive particle and a resin, and pores that are present inside the porous sheet are filled with laminated resin. The average hole diameter of the pores inside the porous sheet may be smaller than the average particle size of the conductive particle. Thereby, it is possible to make the insulating layer of the circuit board securing the interlayer electrically connection by an inner via hole including a conductive paste to be homogenized and ultra-thin and improve the reliability of the connection of the inner via hole.
