Printed circuit board incorporating fibers |
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. |

1. A printed circuit board comprising:
a cell portion having cells in which 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, wherein 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; and the through bores, cutting through intersections of the fiber material in the first direction and the fiber material in the second direction, 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.
