Embodiment 1

[0029] figure 1 It is a schematic structural diagram of a circuit board provided by an embodiment of the present invention.

[0030] Such as figure 1 As shown, the circuit board provided by the embodiment of the present invention includes a circuit board body 10 and a shielding film layer 11 , and also includes a dielectric layer 12 , and the dielectric layer 12 is disposed between the circuit board body 10 and the shielding film layer 11 .

[0031] Specifically, such as figure 1 As shown, the circuit board includes a circuit board body 10, a dielectric layer 12 and a shielding film layer 11, wherein the dielectric layer 12 and the shielding film layer 11 are sequentially stacked on the front or back of the circuit board body 10, and the dielectric layer 12 and the shielding film layer The layer 11 can also be stacked on the front and back of the circuit board body 10 at the same time. Correspondingly, no matter whether the circuit board is a single-sided board, a double-sid...

Embodiment 2

[0070] The embodiment of the present invention also provides an electronic device, which includes the circuit board as described in the above embodiment.

[0071] In the embodiment of the present invention, the electronic equipment uses a circuit board with a dielectric layer added, and when the circuit board transmits high-frequency signals, the attenuation degree of the signal is reduced, thereby reducing the insertion loss of the circuit board and realizing the circuit board When transmitting high-frequency signals, it has the technical effects of low insertion loss, good signal transmission integrity, simple manufacturing process and low manufacturing cost of circuit boards, which in turn makes electronic equipment better in performance and longer in service life.

Abstract

The invention discloses a circuit board and electronic equipment, the circuit board comprises a circuit board body, a shielding film layer and a dielectric layer, and the dielectric layer is arrangedbetween the circuit board body and the shielding film layer. The dielectric layer is arranged between the circuit board body and the shielding film layer of the circuit board, so that when the circuitboard transmits high-frequency signals, the attenuation degree of the signals is reduced, the insertion loss of the circuit board is reduced, and the reliability of the circuit board is improved. Thetechnical effects that the circuit board has low insertion loss and good signal transmission integrity when transmitting high-frequency signals, the manufacturing process of the circuit board is simple, and the manufacturing cost is low are achieved.
