Printed circuit board and electronic equipment

Abstract

The invention provides a printed circuit board and electronic equipment, and relates to the technical field of printed circuit boards. The circuit board comprises a first differential pair signal line, a second differential pair signal line, first grounding networks, a second grounding network and a multilayer structure, The multi-layer structure comprises a first-layer structure, a second-layer structure and a main ground layer, the first differential pair signal line is arranged on the first-layer structure, the second differential pair signal line is arranged on the second-layer structure,and the first grounding networks are arranged on the first side and the second side of the first differential pair signal line in the wiring direction. The second grounding network is arranged on thefirst side and the second side of the second differential pair signal line along the wiring direction, and the first differential pair signal line and the second differential pair signal line are respectively connected with the main ground layer. The differential pair signal lines are arranged on the adjacent layer structures of the printed circuit board through layered design, so that the performance of the printed circuit board is optimized.

Description

technical field [0001] The present application relates to the technical field of circuit boards, in particular, to a printed circuit board and electronic equipment. Background technique [0002] With the rapid development of science and technology, various electronic products have begun to develop and upgrade rapidly, and printed circuit boards (Printed Circuit Board, PCB board) are playing an increasingly important role in the electronics industry, occupying an absolute control position. As the physical support of electronic products and an important part of signal transmission, printed circuit boards determine the performance, life cycle and market competitiveness of electronic products. [0003] Among them, the design of differential pair signal lines in printed circuit boards is widely used in the industry for its superior anti-interference ability, signal integrity and low loss. However, in the traditional PCB design of differential pair signal lines, the V+ and V- sig...
