BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.

[0018] Figure 1 This is a structural schematic diagram of a camera module PCB connection structure in one embodiment of the utility model; DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0020] The present application proposes a camera module PCB connection structure 10, including a PCB board 100, an FPC board 200 and a connecting board 300, wherein at least one wiring groove 110 is provided on the surface of the PCB board 100, and an ink layer 120 is provided in the wiring groove 110; a first connection end 210 is provided at one end of the FPC board 200, and a second connection end 220 is provided at the other end of the FPC board 200, and the first connection end 210 is electrically connected to the PCB board 100; an input end 310 is provided on the connecting board 300, and the input end 310 is electrically connected to the second connection end 220.

[0021] It should be noted that, because the PCB board 100 is affected by the overall circuit routing, at least one routing groove 110 is provided on the surface of the PCB board 100. This routing groove 110 will reduce the flatness of the PCB board 100, thereby causing the PCB board 100 to deform. Therefore, an ink layer 120 is provided in the routing groove 110 to fill the routing groove 110, thereby improving the overall flatness of the PCB board 100, and reducing the overall deformation of the PCB board 100, thereby achieving the purpose of optimizing the clarity of the mobile phone camera; the PCB board 100 is connected to the FPC board 200 and the connecting board 300 by electrical connection, so that the PCB board 100 and the FPC board 200 and the connecting board 300 can respond quickly and the overall structure is more compact, thereby optimizing the camera module PCB connection structure 10.

[0022] In one embodiment, the ink layer 120 is a solid ink layer. Preferably, the ink layer 120 is set to a black ink layer because black ink has good high temperature resistance and can exist stably in a high temperature environment. High temperature will be generated during the solder masking of the ink layer 120 to the PCB board 100. The black ink can withstand the high temperature without flowing or deforming during the solder masking.

[0023] In one embodiment, the thickness of the ink layer 120 is 5 um to 25 um. Preferably, the thickness of the ink layer 120 is 15 um. At this time, the overall flatness of the PCB board 100 is optimal, and the deformation degree of the PCB board 100 can be optimally reduced.

[0024] In one embodiment, a first reinforcing plate is disposed on the back of the PCB board 100, and the first reinforcing plate and the PCB board 100 are connected by adhesive. Preferably, the first reinforcing plate is a steel sheet, and the purpose is to further reduce the deformation degree of the PCB board 100. In addition, the adhesive connection method will not change the original flatness of the PCB board 100, thereby not causing deformation of the PCB board 100.

[0025] In one embodiment, a second reinforcing plate is provided on the back of the connecting plate 300, and the second reinforcing plate is connected to the connecting plate 300 by adhesive. Preferably, the second reinforcing plate is a steel sheet. By providing the second reinforcing plate, the connecting plate 300 can be more stably connected to other modules.

[0026] In one embodiment, the PCB board 100 and the connecting board 300 are arranged in parallel and the length of the FPC board 200 is smaller than the PCB board 100 and the connecting board 300, thereby making the camera module PCB connection structure 10 more compact and occupying less space.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
