摘要： Removable mask films 303 are formed on the both sides of the substrate having the adhesive layer 302 by applying and drying a resin varnish 304 including a ultraviolet-absorbing agent, and fine through holes 306 are formed by using a third harmonics YAG solid-state laser light with a relatively short wavelength not longer than that in the ultraviolet range in such a way that the effects of such a residual strain as the conventional embodiment forming a removable mask film by a laminating process may be decreased as well as the more fine hole drilling compared with conventional embodiment using the carbon dioxide gas laser with a relatively long wavelength may be performed.

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 plurality of double-sided boards using a film are attached to each other with a paste coupling layer sandwiched therebetween. In the paste coupling layer, a conductive paste is filled into a through hole formed in provisionally hardened resin, which is hardened. At the same time, second wirings are electrically coupled to each other by using the hardened conductive paste filled in the through holes that have been previously formed in the paste coupling layer. Thus, it is possible to provide a thinned multilayer printed wiring board without using an adhesive.

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.
