Document Type and Number:
WIPO Patent Application WO/2023/045276
Kind Code:
A1
Abstract:
Embodiments of the application relate to the technical field of signal transmission, and in particular to a printed circuit board and a signal transmission system. In the printed circuit board, a first signal line (140) extends from a first differential signal hole pair (121) of a first column structure unit (120) to the side of a second column structure unit (130) away from the first column structure unit through a space between a second hole section (135) and a fourth hole section (137), or, a first signal line (340) extends from a first differential signal hole pair (321) of a first column structure unit (320) to the side of a second column structure unit (330) away from the first column structure unit (320) through a space between two adjacent second ground holes (332).
