Embodiment 1

[0036] Such as figure 1 As shown, the PCB board 100 according to the embodiment of the present invention includes multiple conductive layers stacked on top of each other. The multi-layer conductive layer includes a first conductive layer and a second conductive layer adjacent to the first conductive layer. On the first conductive layer The first wiring line 1 is laid, the second wiring line 2 is arranged on the second conductive layer, the area of ​​the first wiring line 1 is S, and the projection of the second wiring line 2 on the first conductive layer overlaps with the first wiring line 1 The area of ​​is S', S and S' satisfy: 1 / 4≤S' / S≤3 / 5.

[0037]The angle between the extending direction of the first wiring line 1 and the extending direction of the second wiring line 2 is α, where α=90°, that is, the first wiring line 1 and the second wiring line 2 are vertically arranged. The first wiring line 1 extends in the horizontal direction, the second wiring line 2 extends in th...

Embodiment 2

[0039] Such as figure 2 As shown, the structure of this embodiment is substantially the same as that of Embodiment 1, except that the extension direction of the first wiring line 1 is the same as that of the second wiring line 2, and the second wiring line 2 is on the first conductive layer. The projection of is located on one side of the first wiring line 1, and the signal interference between the first conductive layer and the second conductive layer only occurs on one side of the first wiring line 1, which greatly reduces the gap between the first conductive layer and the second conductive layer. signal interference, improve the quality of signal transmission, and improve the performance of the product.

[0040] At the same time, during the pressing process, the first conductive layer and the second conductive layer will not form a large gap, ensuring that the connection between the first conductive layer and the second conductive layer will not be cut off during the PCB p...

Abstract

The invention discloses a PCB and a mobile terminal possessing the PCB. The PCB comprises multilayer laminated-placed conducting layers. The multiple conducting layers comprise a first conducting layer and a second conducting layer adjacent to the first conducting layer. A first wiring line is paved on the first conducting layer and a second wiring line is arranged on the second conducting layer. An area of the first wiring line is S. The second wiring line is projected on the first conducting layer and an overlapped area with the first wiring line is S', and the S and the S' satisfy the following condition that S' / S is greater than or equal to 1 / 4 and is less than or equal to 3 / 5. According to the PCB of the invention, the overlapped area S' of a projection of the second wiring line on the first conducting layer and the first wiring line and the first wiring line area S satisfy the following condition that S' / S is greater than or equal to 1 / 4 and is less than or equal to 3 / 5, therefore, mutual interference of signals between the first conducting layer and the second conducting layer can be reduced, first wiring line and second wiring line signal transmission performance is increased and work reliability of the PCB 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 having the same. Background technique [0002] With the rapid development of electronic products, the body of the product tends to be thinner and lighter, and the space layout inside the product will become more and more compact. In the related art, the PCB wiring on adjacent layers is likely to cause mutual interference between signals, thereby affecting the normal operation of the PCB board. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a PCB board, which has the advantage of less interference of adjacent layer circuit signals. [0004] The present invention also proposes a mobile terminal, which includes the above-mentioned PCB board. [0005] The PCB board according to the embodi...
