Embodiment 1

[0035] like figure 1 As shown, the PCB board assembly 100 according to the embodiment of the present invention includes a chip 1 , a board body 2 and a conductive member 3 .

[0036] Wherein, the board body 2 is provided with a grounding point and includes multiple conductive layers stacked on top of each other. The multi-layer conductive layer includes a first conductive layer 21 and a second conductive layer 22 adjacent to the first conductive layer 21. The chip 1 is arranged on On the first conductive layer 21, the sensitive circuit of the chip 1 is located close to the first conductive layer 21, and the first conductive layer 21 is provided with a square groove 23 at a position directly below the chip 1, and the groove 23 penetrates the first conductive layer 21. A conductive layer 21 , the conductive element 3 is a copper sheet, the conductive element 3 is laid on the second conductive layer 22 and opposite to the groove 23 , and the conductive element 3 is electrically c...

Embodiment 2

[0039] like figure 2 As shown, the structure of the present embodiment is substantially the same as that of the first embodiment, wherein the same components use the same reference numerals, and the only difference is that there are multiple grooves 23 distributed at intervals along the circumferential direction of the chip 1 .

Embodiment 3

[0041] like image 3 As shown, the structure of the present embodiment is substantially the same as that of the first embodiment, wherein the same components use the same reference numerals, and the only difference is that there is one groove 23 extending along the circumferential direction of the chip 1 .

[0042] The mobile terminal according to the embodiment of the present invention includes the above-mentioned PCB board assembly 100, and by arranging the above-mentioned PCB board assembly 100, the working reliability of the mobile terminal can be improved.

[0043] In some embodiments of the present invention, the mobile terminal can be a mobile phone, a notebook computer, or a tablet computer. When the above-mentioned PCB board assembly 100 is used in mobile phones and the like, the reliability of their work can be improved.
