    • PROBLEM TO BE SOLVED: To provide a multilayer wiring board making it possible to mount a surface mount component having a narrow pitch, while increasing a wiring housing amount and suppressing a warpage amount.SOLUTION: A multilayer wiring board includes: a first metal foil wiring layer having at least two layers of metal foil wiring, arranged on a side of a mounting face for mounting a surface mount component; a wire wiring layer having an insulation coated wire, arranged on an inner layer side of the first metal foil wiring layer; a second metal foil wiring layer arranged on a side opposite to a mounting face for mounting the wire wiring layer; and an inter-layer conduction hole electrically connecting the metal foil wiring on a surface of the first metal foil wiring layer to the metal foil wiring in the inner layer of the first metal foil wiring layer or the insulation coated wire of the wire wiring layer or the second metal foil wiring. A hole diameter of the inter-layer conduction hole varies in a plate-thickness direction of the multilayer wiring board.
    • 要解决的问题:提供一种多层布线板,其可以在增加布线容纳量并抑制翘曲量的同时安装具有窄间距的表面安装部件。解决方案:多层布线板包括:第一金属箔布线 层,具有至少两层金属箔布线,布置在用于安装表面安装部件的安装面的一侧; 具有绝缘被覆线的布线层布置在所述第一金属箔布线层的内层侧上; 第二金属箔布线层,布置在与用于安装所述布线层的安装面相对的一侧上; 以及将第一金属箔布线层的表面上的金属箔布线电连接到第一金属箔布线层的内层中的金属箔布线或布线层的绝缘被覆线的层间导电孔,或 第二金属箔布线。 层间导电孔的孔径在多层布线基板的板厚方向上变化。

    • PROBLEM TO BE SOLVED: To increase a degree of adhesion of a metal film formed on an inner wall of a through hole formed in a single-layer insulating substrate, thereby obtaining a container for an electronic component, whose size and height have been reduced, and an electronic device using the container.SOLUTION: A circuit board 1 includes: a single-layer insulating substrate 10; a through hole 15; and wiring conductors 20a and 20b provided for respective principal planes of the single-layer insulating substrate. The through hole 15 includes: a first recess 15a and a second recess 15b formed for respective principal planes of the single-layer insulating substrate; and a through part 15c for establishing communication between the recesses. An aperture area of an overlapping part between the first recess 15a and the second recess 15b is 1/2 or less of an aperture area of larger one of the recesses and a metal film 16 is formed for each of inner wall surfaces of the first recess 15a, the second recess 15b, and the through part 15c.
    • 要解决的问题:为了增加形成在形成于单层绝缘基板中的通孔的内壁上的金属膜的附着度,从而获得其尺寸和高度具有的电子部件容器 并且使用该容器的电子设备。 电路板1包括:单层绝缘基板10; 通孔15; 以及为单层绝缘基板的各主面设置的配线导体20a,20b。 通孔15包括:为单层绝缘基板的各主平面形成的第一凹部15a和第二凹部15b; 以及用于建立凹部之间的连通的贯通部15c。 第一凹部15a和第二凹部15b之间的重叠部分的开口面积为凹部中的一个的开口面积的1/2以下,并且对于第一凹部15a的内壁面的每一个形成金属膜16 15a,第二凹部15b和贯通部15c。 版权所有(C)2013,JPO&INPIT
