    摘要: A printed circuit board includes a cell portion which includes cells having a plurality of through bores are arranged in a base material; and a base material portion which exists around an outer edge of the cell portion. The base material is formed of a prepreg, the prepreg includes a fiber material in which fiber threads are oriented in a first direction and in a second direction which is perpendicular to the first direction, and a resin material in which the fiber material is impregnated. The through bores are arranged along a third direction between the first direction and the second direction, wherein one side of the outer edges of the cell extends along the third direction.

    摘要: Large-sized through holes are formed in a core layer of a printed wiring board. Large-sized vias are formed in the shape of a cylinder along the inward wall surfaces of the large-sized through holes located within a specific area. A filling material fills the inner space of the large-sized via. A small-sized through hole penetrates through the corresponding filling material along the longitudinal axis of the small-sized through hole. A small-sized via is formed in the shape of a cylinder along the inward wall surface of the small-sized through hole. The filling material and the core layer are uniformly distributed within the specific area in the in-plane direction of the core substrate. This results in suppression of uneven distribution of thermal stress in the core layer in the in-plane direction of the core layer.

    摘要: It is an object of the present invention to enhance laser beam transmitting efficiency by accurately controlling an interval between a light emitting (light receiving) element (20) and an optical wave-guide substrate (1) without causing any fluctuation in the interval in a mounting structure of the light transmitting element in which the light emitting (light receiving) element (20) is mounted on the optical wave-guide substrate (1). When the light emitting (light receiving) element is joined to the sub-mount chip (4) and when the sub-mount chip (4) is joined to the optical wave-guide while the element is being directed to the substrate side, the sub-mount chip and the optical wave-guide substrate are joined to each other by the solder bump (6). A post (5) is arranged for regulating an interval between the light emitting (light receiving) element and the optical wave-guide substrate.
