Abstract

The invention provides a PCB. The PCB comprises a top layer, a bottom layer and at least two middle layers arranged between the top layer and the bottom layer, wherein the middle layer comprises a second layer and a third layer, the top layer is provided with a pair of series capacitors on a differential line, the area of the series capacitor where the top layer is located is a capacitor series distribution area, a wiring forbidding area is arranged at the position, corresponding to the capacitor series distribution area, of the second layer, the wiring forbidding area is larger than the capacitor series distribution area, a GND attribute area is arranged at the position, corresponding to the wiring forbidding area, of the third layer, and the GND attribute area provides reference for thedifferential line of the top layer. The PCB is advantaged in that problems of how to counteract hopping of impedance of an impedance line, guarantee correct transmission, improve the signal quality ofa transmission signal and the like can be solved.

Description

technical field [0001] The invention relates to the field of electronic technology, and more specifically, relates to a PCB board with signal integrity and reliability that can be widely used in packaging parts. Background technique [0002] Nowadays, electronic products are developing towards thinner and lighter, and the speed of replacement is also increasing. Functional requirements are becoming more and more abundant. Requirements for important electronic components of electronic products, supports for electronic components, and PCBs for carriers of electrical connections for electronic components It is also becoming more and more stringent, and the requirements for the integrity of PCB signals and product reliability are getting higher and higher. [0003] exist Picture 1-1 and Figure 1-2 In the shown embodiment, the PCB board is N layers, in which the conductive layers are separated by an insulating layer, S is the distance between the border of the series capacitor...
