[0026] It should be noted that the establishment of the PCB Vcut standard is of great significance to ensure product quality and improve production efficiency. It involves the specification of V-cut depth, angle, position and other aspects to ensure that the circuit board is not damaged during splitting, while ensuring that the size of the separated unit board is accurate and the edge is smooth. Especially for multi-layer, high-density and high-precision circuit boards, the application of V-cut technology is indispensable.

[0027] PCB designers do not consider V-CUT processing during splitting. No identification is added during PCB design, and the factory usually uses machines to split the board. However, some special boards or multiple boards are not easy to split by machine, and manual splitting is required. Manual splitting may not accurately identify the V-shaped split line, and careful checking is required before splitting, which reduces the accuracy of splitting.

[0028] As shown in Figs. 1-3 The present embodiment provides a circuit board structure with V-CUT identification on the edge of the split board. A split identification 12 is provided at the corresponding position of the V-shaped split line 11, which can quickly identify the split area. Under the guidance of the identification area 121, the V-shaped split line 11 can be quickly identified, which can effectively improve the identification accuracy and speed of manual splitting, and can easily identify the position of the split board, thereby improving the efficiency of splitting.

[0029] Specifically, the circuit board structure with V-CUT identification on the edge of the split board includes a circuit board 10, the circuit board 10 is provided with a plurality of V-shaped split lines 11, the V-shaped split lines 11 are used to separate the circuit board 10 into a plurality of split board areas, the circuit board 10 is provided with a split identification 12 at the corresponding position of the V-shaped split line 11, the split identification 12 is used to identify the split board area, the split identification 12 includes a plurality of identification areas 121, the identification areas 121 are respectively located in one split board area, and the adjacent identification areas 121 located on both sides of the V-shaped split line 11 are connected to each other. The identification areas 121 are respectively located in the split board area, which can easily identify the split board area. The adjacent identification areas 121 located on both sides of the V-shaped split line 11 are connected to each other, and the splitting is performed along the V-shaped split line 11 at the adjacent identification areas 121 connected to each other. Under the guidance of the identification area 121, the V-shaped split line 11 can be quickly identified, which can improve the splitting efficiency.

[0030] In one embodiment, the distance between adjacent identification areas 121 is not less than the width of the V-shaped split line 11. The identification areas 121 are provided in the split plate area, which provides visual guidance while ensuring that the presence of the identification areas 121 does not interfere with or weaken the function of the V-shaped split line 11, thereby ensuring the accuracy and efficiency of the split plate operation. The V-shaped split line 11, as a key structure for splitting, has a width and depth that are precisely calculated to ensure that it can be smoothly cut along the predetermined path during splitting. If the identification areas 121 are too close to the V-shaped split line 11, they may cause unnecessary physical interference, thereby affecting the splitting effect.

[0031] In one embodiment, the distance between the identification areas 121 and the edge of the circuit board 10 is D1, and D1 is not greater than 20 mm. Keeping the distance between the identification areas 121 and the edge moderate can ensure that the operator can clearly see the identification areas 121 during the splitting process, thereby quickly and accurately positioning the area to be split.

[0032] In one embodiment, adjacent identification areas 121 are connected by traces 122, and the width of the traces 122 is not greater than the width of the identification areas 121. The width of the traces 122 is strictly controlled to ensure that it does not exceed the width of the adjacent identification areas 121, which helps to reduce the occupied space while maintaining a neat and efficient layout. Preferably, the width of the traces 122 is 0.2 mm. A line width of 0.2 mm is thin enough to effectively reduce the space occupied by the traces 122, making the overall layout more compact. On the other hand, such a line width not only ensures reliable connection, but also meets the requirements of production processes, facilitating manufacturing and processing.

[0033] In one embodiment, the identification areas 121 are provided with a no-print area 123. The no-print area 123 is not only set to avoid wiring and copper skin inside the circuit board 10, but also to improve the ease of identification of the identification areas 121 and ensure that the identification areas 121 are clearly visible. The distance between the edge of the no-print area 123 and the edge of the identification areas 121 is D2, and D2 is not less than 0.2 mm and not greater than 0.5 mm. This meets the demand for space utilization while ensuring the identification effect of the identification areas 121.

[0034] Preferably, the distance between the edge of the no-print area 123 and the edge of the identification areas 121 is 0.3 mm. A distance of 0.3 mm can effectively prevent wiring interference and ensure that the identification areas 121 are clearly visible, thereby improving the practicality and aesthetics of the overall layout.

[0035] The trace 122 is externally provided with a forbidden area 123, and the distance between the edge of the forbidden area 123 and the edge of the trace 122 is equal to the distance between the edge of the identification area 121 and the edge of the forbidden area 123. In order to ensure the uniformity and consistency of the layout, the distance between the edge of the forbidden area 123 and the edge of the trace 122 is equal to the distance between the edge of the identification area 121 and the edge of the forbidden area 123, that is, D2. Such a design not only helps to keep the layout of the circuit board 10 neat and orderly, but also further improves the identification efficiency of the identification area 121 and the trace 122, and provides convenience for the subsequent manufacturing and assembly process of the circuit board 10.

[0036] In one embodiment, the identification area 121 is circular, and the diameter of the circular identification area 121 is 1.5 mm. It ensures that the identification area 121 has enough space to display the necessary identification information, and also ensures the compactness and efficiency of the entire circuit board 10 layout.

[0037] In order to facilitate the subsequent assembly and testing process, the distance between the identification areas 121 on both sides of the V-shaped division line 11 is set to 3.5 mm. It not only ensures that there is enough space between the identification areas 121 to avoid potential conflicts, but also ensures the compactness and efficiency of the entire circuit board 10 layout.

[0038] It should be understood that those skilled in the art can make improvements or changes according to the above description, and all such improvements and changes shall fall within the protection scope of the appended claims of the present application.

[0039] The above describes the present application in conjunction with the drawings, and it is obvious that the implementation of the present application is not limited to the above manner. Any improvement or change of the method concept and technical solution of the present application, or direct application of the concept and technical solution of the present application to other occasions without improvement, all fall within the protection scope of the present application.
