Example Embodiment

[0045]The technical solutions in the present application embodiment will be described in conjunction with the drawings of the present application embodiments. Obviously, the described embodiments are merely a part of the embodiments of the present application, not all of the embodiments. Based on the embodiment of the present application embodiment, there are various embodiments obtained by those of ordinary skill in the art without creative labor premise, and are the scope of the present application.

[0046]The present application embodiment provides a printed circuit board and an electronic device that designs a layered wiring method on a printed circuit board. Since the differential pair signal line has superior anti-interference ability, the signal is complete, and the low loss is a bit, The two signal lines of the differential pair of signal lines are arranged on different levels of the multilayer structure of the printed circuit board, and the performance of the printed circuit ...

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...
