    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a wiring board which can inspect a conductor pattern of a wiring board in a state in which the wiring board is supported by a support plate.SOLUTION: A wiring board 20 includes a test wiring pad 36 which is connected to a connection pattern 34 connected to a pad 60P arranged below an interlayer resin insulation layer 50 of the outermost layer on the second surface side of the wiring board 20. Because a test wiring pad 158T connected to the pad 60P is provided on an interlayer resin insulation layer 150 of the outermost layer on the exposed first surface side, the inspection of the conductor pattern can be performed in a state in which the wiring board 20 is supported by a support plate 30 which cannot bring an inspection probe into contact with the pad 60P for external connection of the wiring board.
    • 要解决的问题:提供一种制造布线板的方法,该布线板可以在布线板由支撑板支撑的状态下检查布线板的导体图案。解决方案:布线板20包括测试布线垫 36连接到连接到布线板20的第二表面侧上的最外层的层间树脂绝缘层50下方的焊盘60P的连接图案34.因为连接到焊盘60P的测试布线焊盘158T 在暴露的第一表面侧的最外层的层间树脂绝缘层150上,导体图案的检查可以在布线板20由不能使检查探针进入的支撑板30支撑的状态下进行 与焊盘60P接触,用于布线板的外部连接。

    • PROBLEM TO BE SOLVED: To provide a multilayer printed wiring board in which electric connection with an inner layer circuit in a core substrate can sufficiently be secured through a through-hole, even if the core substrate is made into multiple layers, and which is advantageous to high density of the through hole. SOLUTION: In the multilayer printed wiring board, a built-up wiring layer is formed where an interlayer resin insulating layer and a conductor layer are alternately laminated on the multilayer core substrate having a conductor layer in an inner layer, and the conductor layers are connected in a via hole. A plurality of the conductor layers formed on the multilayer core substrate by an etching processing in a state where a nonelectrolytic plating film and an electrolytic plating film are given, are installed. The through-hole is formed in the multilayer core substrate. The through-hole is filled with a fill, and an exposure face of the fill from the through-hole is covered with a part of a plurality of the conductor layers. The via hole is connected to the conductor layer covering the exposure face. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:即使将芯基板制成多层,也可以通过贯通孔提供与核心基板中的内层电路的电连接能够充分固定的多层印刷电路板,以及 这对于通孔的高密度是有利的。 解决方案:在多层印刷线路板中,形成叠层布线层,其中层间树脂绝缘层和导体层交替层叠在具有内层中的导体层的多层芯基板上,导体 层连接在通孔中。 通过在非电解电镀膜和电解电镀膜的状态下通过蚀刻处理在多层芯基板上形成的多个导体层被安装。 通孔形成在多层芯基板中。 通孔填充有填充物,并且来自通孔的填充物的曝光面被多个导体层的一部分覆盖。 通孔连接到覆盖曝光面的导体层。 版权所有(C)2007,JPO&INPIT
