[0025] The mobile terminal of this embodiment includes a PCB board, where image 3 As shown, the PCB board of this embodiment is composed of a wiring layer board 101 and a wiring layer board 102. In this embodiment, the wiring layer board 101 and the wiring layer board 102 are insulated from each other, so that the wiring layer No interference such as collusion occurs between the wiring on the board 101 and the wiring on the wiring layer 102.

[0026] In addition, an insulating layer can be further filled between the wiring layer plate 101 and the wiring layer plate 102, so that the wiring layer plate 101 and the wiring layer plate 102 are insulated from each other while still further The ground reduces the electromagnetic interference between the wiring laminate 101 and the wiring laminate 102.

[0027] Where as figure 1 As shown, the wiring layer board 101 of the PCB board in this embodiment has a display area 1011 and a keyboard area 1012 corresponding to the display screen of a...

[0037] Such as Figure 5 As shown, the difference between the mobile terminal of this embodiment and the mobile terminal of the first embodiment is:

[0038] In this embodiment, the radio frequency chip 4, the Bluetooth chip 7 and the FM chip 8 are covered by a shielding cover 131, and the memory 5 and the baseband chip 6 are covered by another shielding cover 132. The shielding cover 131 and the shielding cover 132 shield the interference of external electromagnetic signals to the chip.

[0039] Moreover, in this embodiment, ground wires (not shown in the figure) are provided on both sides of the wiring 14, wherein the ground wires are kept parallel to the wiring 14, and the ground wires are also kept parallel to the wiring 14 A certain distance, such as 20 μm, and the distance can be changed according to design requirements. The ground wire can effectively prevent the interference of the wire signal in the wire 14 to external electromagnetic signals and the crosstalk to the wir...

Abstract

The invention discloses a mobile terminal which comprises a printed circuit board (PCB), wherein the PCB comprises a first routing laminate and a second routing laminate; both the first routing laminate and the second routing laminate are used for mounting a plurality of electronic elements and routes of the electronic elements. In the mobile phone, by two layers of PCBs, the cost is reduced greatly, so the development of the mobile phone is extended; furthermore, the interference of external electromagnetic waves on the electronic elements is reduced in a shielding shade; moreover, the routes of the electronic elements are isolated and encircled by ground wires, so that the crosstalk of signals among the routes is reduced.

Description

Technical field [0001] The invention relates to a mobile terminal, in particular to a mobile terminal adopting a two-layer PCB board. Background technique [0002] With the rapid development of the communications industry, competition in the mobile terminal market has become increasingly fierce. The price of mobile terminals, especially the price of mobile phones, has become an important aspect of mobile terminal product competition. Therefore, in the development of mobile phones, the requirements for cost control are becoming stronger and stronger. [0003] But even low-end mobile phones have many functions that can be realized. In addition to calling and instant messaging, FM (frequency modulation), camera, Bluetooth, and loudspeaker functions are also indispensable. However, to ensure the realization of these functions , PCB boards (printed circuit boards) with 4 layers and above are almost uniformly used in the research and development of mobile terminals. [0004] The 4-layer ...
