    Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board with big peel strength, and a method for manufacturing a printed circuit board and a printed circuit board finishing machine capable of shortening a manufacturing time and reducing a manufacturing cost. SOLUTION: The method for manufacturing a printed circuit board 1 includes the steps of forming a resist layer 5 on a surface of the board 1 whose surface is an insulating layer 2a, irradiating a position (a first position) that is connected to a conductive pattern 3 in an inner layer with a CO 2 laser from a surface side of the layer 5 to form a hole 6 that is to be connected to the pattern 3 from the surface of the layer 5, forming a hole 8 and a trench 9 with each depth that are not connected to the conductor layer in the inner layer at second positions from the surface of the layer 5 by irradiating the positions (the second positions) where a pattern with the first position is formed with an excimer laser (a second laser), filling conductive substances in the holes 6, 8 and the trench 9 to form the conductive patterns 11, 12, and allowing a part of the conductive patterns to be protruded from the surface of the layer 2a by removing the layer 5.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a circuit board structure that enhances adhesion between a circuit and a dielectric layer. SOLUTION: A core board coated with at least a first circuit layer is provided, and a dielectric layer is formed on the surface of the core board. First and second openings are formed on the dielectric layer, and an electrode pad of the first circuit layer is exposed from the second opening, and then a metal layer is formed to cover the surface of the dielectric layer and the first and second openings. Subsequently, the metal layer is removed from the surface of the dielectric layer, and a second circuit layer is formed on the first opening of the dielectric layer, and then a conductive structure electrically connected to the first circuit layer is formed on the second opening.

    Abstract: PROBLEM TO BE SOLVED: To provide a multilayered printed wiring board capable of realizing a high density conductor pattern and of improving reliability of a through-hole conductor by making thin the thickness of a panel plated layer by increasing the thickness of the through-hole conductor and increasing a connection area of the through-hole conductor and the panel plated layer. SOLUTION: After a plated resist film is formed on a wiring board base member 1 as a core member of the multilayered printed wiring board, a through-hole 3 is formed, and the through-hole conductor 4 is formed along a wall surface of the through-hole 3 and along a through-hole surface in the plated resist film 2 to form a protruded part 4a on the through-hole conductor 4. After the plated resist film is peeled, the panel plated layer 5 is formed on the wiring board base member 1 and on the surface of the through-hole conductor 4, whereby the through-hole conductor 4 and the panel plated layer 5 are connected in the state of the protruded part 4a covered so that it is possible to increase a connection area.
