Fig. 1 shows a schematic view of an application scenario of a circuit board provided in an embodiment of the present application, and referring to fig. 1, for example, a mobile terminal includes a middle frame 20, a plurality of cameras, and a circuit board 10 provided in an embodiment of the present application, where the middle frame 20 generally includes a middle plate and a frame 21 disposed around the middle plate, the circuit board 10 is installed in the frame 21, and the plurality of cameras are installed in a partial area (e.g., an area K in fig. 1) of the circuit board 10.

In order to solve the technical problem that the circuit board in the prior art is poor in commonality, the embodiment of the present application provides a circuit board.

Fig. 2 is a schematic diagram illustrating a partial structure of a circuit board according to an embodiment of the present application, please refer to fig. 2. The circuit board 10 provided by the embodiment of the present application includes a substrate 100, where the substrate 100 is used to support electronic components; for example, when the circuit board 10 is a PCB (Printed circuit board), the substrate 100 may include a plurality of layers of circuits and a dielectric layer (also called a substrate) for insulating the different layers of circuits, and the structure thereof may be a conventional structure known in the art and will not be described herein.

With continued reference to fig. 2, the substrate 100 includes a mounting region 110, the mounting region 110 illustratively includes a first sub-mounting region 111 and a second sub-mounting region 112 arranged along a first direction F1, through holes penetrating through the substrate 100 are formed in the first sub-mounting region 111 and the second sub-mounting region 112, the through holes in the first sub-mounting region 111 and the through holes in the second sub-mounting region 112 can be communicated through the openings of the substrate 100 to form a larger through hole, but it should be understood that the first sub-mounting region 111 and the second sub-mounting region 112 are independent regions with a certain gap therebetween; or there may be two independent through holes, and each through hole may be square or circular, and is not limited herein.

A first connector 131 fixed on the surface of the substrate 100 is disposed in the first direction F1 of the first sub-mounting region 111, the first connector 131 is electrically connected to a circuit in the circuit Board 10 and is used for electrically connecting to a camera in the first sub-mounting region 111, so as to electrically connect the camera to the circuit in the circuit Board 10, and the first connector 131 may be a Board-to-Board connector (BTB) or other Connectors capable of being connected to the camera; here, the first connector 131 is located in the first direction F1 of the first sub-mounting region 111 only by way of example, and may be located at other positions around the first sub-mounting region 111. Similarly, the second sub-mounting region 112 has a second connector 132 fixed to the surface of the substrate 100 in the first direction F1, and the type and relative arrangement of the second connector 132 can be referred to the first connector 132 and used to electrically connect with the camera in the second sub-mounting region 112 to electrically connect the camera with the circuit in the circuit board 10.

In the substrate 100, there is also one first reserved region 121 in the first direction F1 of the second sub-mounting region 112 and one second reserved region 122 in the second direction F2 of the second sub-mounting region 112, wherein the meaning of "reserved region" means: when the circuit board 10 is not assembled in a mobile terminal, the surface of the substrate 100 is not provided with electronic components and may be used in a region where a camera is mounted, but a wiring may be provided in the region. Wherein the first direction F1 is perpendicular to the second direction F2.

Furthermore, a common connector 133 is provided in the second direction F2 of the first reserved area 121, the type and relative arrangement of the common connector 133 being referred to the first connector 131, the common connector 133 being located in the first direction F1 of the second reserved area 122. When the circuit board 10 is used for assembly, the common connector 133 can select whether to provide a camera in the first reserved area 121 or the second reserved area 122 as needed, and the camera can be electrically connected to the common connector 133 regardless of whether the camera is installed in the first reserved area 121 or the second reserved area 122. Therefore, the shared connector 133 can be "shared" by the first reserved area 121 and the second reserved area 122. The shared connector 133 may have only one interface, and the cameras are connected to the interface of the shared connector 133 when being installed in the first reserved area 121 and the second reserved area 122; the common connector 133 may also have two interfaces, wherein one interface faces the first reserved area 121, and the other interface faces the second reserved area 122, so that when the camera is installed in the first reserved area 121, the flexible circuit board is connected to the interface of the common connector 133 facing the first reserved area 121 through the flexible circuit board, and the flexible circuit board is not easily twisted; similarly, when the camera is mounted in the second reserved area 122, the camera can also be electrically connected to the interface of the common connector 133 facing the second reserved area 122 through another flexible circuit board. The shared connector 133 can simultaneously take into account that a camera is mounted in any one of the first reserved area 121 and the second reserved area 122, and does not need to be a separate mating connector for the first reserved area 121 and the second reserved area 122, so that the number of connectors to be arranged is reduced, the cost is saved, and the space on the surface of the substrate 100 is saved.

Two bent strip-shaped first hollow structures 121s are arranged along the edge of the first reserved area 121, wherein the two first hollow structures 121s are oppositely arranged at two sides of the first reserved area 121, so that the part of the substrate 100 located in the first reserved area 121 is connected with the remaining part of the substrate 100 only by the reserved part, and the first hollow structures 121s around the first reserved area form a first prefabricated hole, but the form of the first hollow structures is not limited to the form in fig. 2, as long as it is ensured that only the part of the edge of the reserved part around the first reserved area is connected with the remaining part of the substrate 100, for example, the first hollow structures can also be round holes penetrating through the substrate 100, and a plurality of the round holes are arranged at intervals along the edge of the first reserved area, and can also be made into first prefabricated holes. When a camera needs to be installed in the first reserved area 121, the structure of the substrate 100 located in the first reserved area 121 may be pressed to break the structure of the substrate 100 located in the first reserved area 121 and the rest of the substrate 100, the first preformed hole forms a through hole, and the camera is placed in the first reserved area 121 of the through hole to penetrate through the substrate 100.

Similarly, two second hollow structures 122s are also exemplarily disposed along the edge of the second reserved area 122 to form a second preformed hole.

At this time, the first camera 211, the second camera 221, and the third camera 231 are disposed in the same row; the first camera 211 and the second camera 221 form a first camera group, and the third camera 231 forms a second camera group. Also, the structure of the substrate 100 in the second reserved region 122 is not removed, and therefore, other electronic components may also be arranged by using the arrangement area in the second reserved region 122, such as providing a flash lamp 152 in the second reserved region 122, and, as needed, providing one flash lamp 152 in the second direction F2 of the first reserved region 111. It should be noted that the locations of the flash 151 and the flash 152 are merely exemplary, and the flash may also be disposed on a camera and a corresponding connector flexible circuit board, such as the surfaces of the first flexible circuit board 212, the second flexible circuit board 222, and the third flexible circuit board 232, which is beneficial to saving the surface area of the substrate 100 for mounting other electronic components.
