    Abstract: The present invention provides a printed-wiring board which can make the electric wiring densified and can be thinned, even when having a BVH of a non-penetration hole filled with a selectively plating, formed therein for interfacial connection means. The printed-wiring board has a blind via hole connecting different wiring-pattern-formed layers with each other, wherein the blind via hole is a non-penetration hole filled with a plating, and the plating is not formed on a wiring pattern including the round of the blind via hole. The process for manufacturing the printed-wiring board having a blind via hole connecting different wiring-pattern-formed layers with each other includes the steps of: sequentially layering at least a metallic foil and a barrier metal layer to be differently etched from the metallic foil, on an insulation layer; preparing such a non-penetration hole as to reach a desired wiring-pattern-forming layer, by directly irradiating the barrier metal layer with a laser beam; cleaning the inside of the non-penetration hole by desmearing treatment; filling the non-penetration hole with a plating, and at the same time forming a plating on the barrier metal layer, by plating treatment; removing the plating which has been formed on the barrier metal layer and protrudes from the non-penetration hole, by etching treatment; peeling the barrier metal layer; and etching the metallic foil to form a wiring pattern.

    Abstract: An adhesive-free multilayered metal laminate having a given thickness which is obtained by bonding a metal sheet having a thin metal film on a surface thereof to a metal foil without using an adhesive; and a process for continuously producing the laminate. The process comprises the steps of; setting a metal sheet on a reel for metal sheet unwinding; setting a metal foil on a reel for metal foil unwinding; unwinding the metal sheet from the metal sheet-unwinding reel and activating a surface of the metal sheet to thereby form a first thin metal film on the metal sheet surface; unwinding the metal foil from the metal foil-unwinding reel and activating a surface of the metal foil to thereby form a second thin metal film on the metal foil surface; and press-bonding the activated surface of the first thin metal film to that of the second thin metal film so that the first thin metal film formed on the metal sheet is in contact with the second thin metal film formed on the metal foil.
