    摘要: It is an object of the present invention to provide a multilayer circuit board, and a method for manufacturing the same, in which a plurality of circuit boards are layered, wherein as regards at least one circuit board positioned on an outer side, a conductive substance is filled into holes passing through the circuit board in the thickness direction and cured, and the wiring layers of the plurality of circuit boards are electrically connected by the conductive substance that has been cured, wherein in the multilayer circuit board, the wiring layer positioned outside the conductive substance that has been cured projects outward from its surroundings. Thus, the conductive paste is sufficiently compressed during hot pressing to yield a stable electrical connection, and thermosetting resin can be filled in between the inner layer wiring pattern without leaving gaps.

    摘要: The present invention provides a method of manufacturing a printed circuit board, which includes preparing a dielectric substrate, coating surfaces of the dielectric substrate, filling a via hole with a conductor, peeling mold-releasing films, compressing the dielectric substrate and forming metal foils. 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.

    摘要: 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.
