    Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board and a method of designing the printed circuit board. SOLUTION: The printed circuit board includes an insulating layer. On the surface of the insulating layer, at least signal lines parallel to each another are wired, and in the insulating layer, an insulating cloth is arranged and the insulating cloth is composed of first fiber lines parallel to each other and second fiber lines perpendicular to the first fiber lines. In the insulating cloth, a rectangular area is formed by a center line of two neighboring first fiber lines and a center line of two neighboring second fiber lines. The orthographic projection of the signal line onto the insulating cloth is not parallel to the first fiber line, the second fiber line, or the diagonal line of the rectangular area. Consequently, part of the signal line passes through the first fiber line and the second fiber line and the other part passes through the rectangular area, and therefore, it is possible to prevent the resistance of the signal line from varying considerably and improve the quality of signal transmission.

    解决方案:印刷电路板包括绝缘层。 在绝缘层的表面上,至少彼此平行的信号线被布线,并且在绝缘层中布置绝缘布,并且绝缘布由彼此平行的第一光纤线和垂直于 第一条光纤线。 在绝缘布中,通过两个相邻的第一光纤线的中心线和两个相邻的第二光纤线的中心线形成矩形区域。 信号线在绝缘布上的正投影不平行于第一光纤线,第二光纤线或矩形区域的对角线。 因此,信号线的一部分通过第一光纤线路,第二光纤线路和另一部分通过矩形区域,因此可以防止信号线路的电阻显着变化并提高其质量 信号传输。 版权所有(C)2008,JPO&INPIT
