    摘要: A wiring substrate includes differential wirings; a first insulating layer adjacent to one side of the differential wirings, including first fiber bundles parallel to the differential wirings; a second insulating layer adjacent to another side of the differential wirings, including second fiber bundles parallel to the differential wirings and disposed by the same pitch as the first fiber bundles; a third insulating layer on the first insulating layer on a side opposite to the differential wirings, including third fiber bundles in parallel to the differential wirings; and a fourth insulating layer on the second insulating layer on a side opposite to the differential wirings, including fourth fiber bundles in parallel to the differential wirings. Intervals of the third and fourth fiber bundles are respectively narrower than intervals of the first and second fiber bundles. The differential wirings are disposed between adjacent first fiber bundles, and between adjacent second fiber bundles.

    摘要: A printed wiring board manufacturing method includes weaving a glass fiber cloth with warp and weft yarns such that the warp and weft yarns are visually distinguishable at least a region. The glass fiber cloth is impregnated with a resin to fabricate a substrate. A copper foil is formed on at least one surface of the substrate to fabricate a core substrate. The copper foil is removed within the region on the core substrate to form an opening. A pitch between the warp yarns or between the weft yarns which are presented in the opening is detected. A pitch between a pair of differential wirings to be patterned is determined based on the detected pitch between the warp yarns or between the weft yarns. The pair of differential wirings is patterned on the core substrate in accordance with the determined pitch between the pair of differential wirings.

    摘要: A depression is formed in a first surface of a printed wiring board. A through hole penetrates through the printed wiring board from the bottom surface of the depression to a second surface of the printed wiring board. The second surface is the opposite surface of the first surface. A terminal of an electronic component is received in the through hole. The terminal has the tip end protruding from the second surface of the printed wiring board. Solder is filled in the through hole. The tip end of the terminal is allowed to protrude from the second surface of the printed wiring board even when the terminal is shorter than the original thickness of the printed wiring board. It is not necessary to change the length of the terminal.
