    摘要: A transfer sheet includes an electrodeposited metal foil having a smooth surface and a rough surface attached to a heatproof flexible base sheet. Using such a transfer sheet, a circuit substrate is formed by etching the electrodeposited metal foil to form a circuit pattern, placing the transfer sheet into a cavity of a mold in such a manner that the rough surface of the circuit pattern faces an inside of the mold cavity, pouring a melting resin into the mold cavity to form a molded article, and peeling the transfer sheet from the molded article so that the circuit pattern remains on the resin base.

    摘要: A circuit board has plated through holes which are laid out with a fine pitch and meets requirements relating to characteristics such as the thermal expansion coefficient of the circuit board. A method of manufacturing a circuit board includes: a step of forming a core portion by thermal compression bonding prepregs which include first fibers that conduct electricity and second fibers that do not conduct electricity, which have the second fibers disposed at positions where plated through holes will pass through, and which are impregnated with resin; a step of forming through holes at positions in the core portion where the second fibers are disposed; and a step of forming a conductive layer on inner surfaces of the through holes to form plated through holes at positions that do not interfere with the first fibers and thereby produce a core substrate.

    摘要: A process for making a circuit board comprises the following steps of: half-etching a metal layer formed on an insulating substrate by means of a first masking which is positioned on an upper surface of the metal layer; applying a positive liquid resist on the half-etched metal layer from an upper side of the first masking; exposing the positive liquid resist with parallel light from the upper side of the first masking and developing the positive liquid resist in such a manner that a part of the positive liquid resist located under the first masking is protected to be unexposed and undeveloped; etching again the metal layer by means of a second masking composed of the first masking and the protected positive liquid resist to form a conductive pattern on the insulating substrate; and removing the first masking and the second masking from the metal layer.
