PCB and terminal equipment adopting PCB

Abstract

The invention discloses a PCB and terminal equipment adopting the PCB. According to the PCB, at least one electric conductor is additionally arranged on an exposed section (or called as an interference wire) on the PCB, so that the exposed section is divided into at least two sections, and therefore, the original circuit of the PCB does not need to be changed in a large range, the problem of noiseinterference can be solved only by slightly changing the exposed section, the indexes such as the impedance and performance of the original circuit of the PCB are hardly affected; the PCB does not need to be remade for re-verification, so that a project period can be shortened, and test resources are greatly saved; the problem of radiation noise generated by the exposed section is thoroughly solved, and the condition that the radiation noise appears repeatedly is avoided.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to the technical field of mobile equipment, and in particular to a PCB board and a terminal device using the PCB board. Background technique [0002] With the continuous development of mobile terminal technology, terminal devices such as mobile phones and tablet computers have become more and more common, and users have higher and higher performance requirements for terminal devices. As we all know, the printed circuit board (PCB for short) is used as the carrier of the terminal equipment to carry the processor, memory, audio and video decoding chips and lay out related circuit lines and components, and its performance directly affects the performance of the terminal equipment. As the integration of terminal equipment is getting higher and higher, the components, thickness, length and width of the PCB board are getting smaller and smaller, but there are more a...

Problems solved by technology

[0004] The embodiment of the present application provides a PCB board and a terminal device using the PCB board. The PCB board adds at least one conductor to the bare section (or interference trace) located on the PCB board, so that the bare section The section is divided into at least two sections, so that it is not necessary to change the original circuit of the PCB board on a large scale, and only need to make minor changes to the exposed section to solve the problem of noise interference, and the impedance and performance of the original circuit of the PCB board, etc. There is almost no impact on the indicators, and there is no need to redo the PCB board for re-verification, which not only greatly saves the project cycle and test resources, but also completely solves the problem of radiation noise generated by the exposed section, so that there will be no repetitions
