Abstract

The invention provides a PCB and a mobile terminal with the same. The PCB comprises a plurality of printed circuit layers, insulation layers, and a plurality of heat dissipation layers. Each printed circuit layer is formed from printed circuits. The printed circuit layers are stacked successively from top to bottom. The top-layer printed circuit layer of the multiple printed circuit layers is connected with an electronic component. Each insulation layer is arranged between every two adjacent printed circuit layers. The multiple heat dissipation layers and the multiple printed circuit layers are arranged on the corresponding insulation layers in one-to-one correspondence. Each heat dissipation layer is located right below the electronic component. The multiple heat dissipation layers are arranged right below the electronic component in the PCB, so that rapid and effective heat dissipation of the electronic component is achieved and the operation reliability of the electronic component and a mobile terminal is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a PCB board and a mobile terminal with the PCB board. Background technique [0002] As people's requirements for the performance of mobile terminals are getting higher and higher, the operation speed of various devices inside the mobile terminal is also getting faster and faster, and the power consumption of various devices is also increasing sharply, resulting in the internal circuit board of the mobile terminal when it is working. Some electronic components on the computer, such as processor chips, transistors, resistors and capacitors, etc., can generate a lot of heat. When the heat accumulates, it will cause abnormal operation of electronic components, burn out or short circuit of the circuit board and the electronic components on it. Therefore, it is very important to dissipate heat quickly and efficiently from the electronic components on the circuit board. [00...
