Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:
[0027] Reference Figure 1-5 A PCB manufacturing plate with no ring design includes a processing substrate 1 and a PCB board body 8. L-shaped warp grooves 2 are provided on both sides of the surface of the processing substrate 1. L-shaped weft grooves 3 are provided on both sides of the surface of the processing substrate 1 perpendicular to the L-shaped warp grooves 2. Limit springs 6 are provided inside the L-shaped warp grooves 2 and the L-shaped weft grooves 3. The ends of the limit springs 6 are respectively connected with warp clamps 4 and weft clamps 5. A material unloading slot 7 is provided at the center of the surface of the processing substrate 1. A PCB board body 8 is provided on the surface of the processing substrate 1. The PCB board is clamped by the warp clamps 4 and weft clamps 5 provided on the surface of the processing substrate 1. The main body 8 is clamped, and the flexible clamping plate design can adapt to PCB board main bodies 8 of different sizes, thereby improving the versatility of the processed substrate 1. The use of the limit spring 6 ensures the stable clamping of the clamping plate to prevent the PCB board main body 8 from moving or shaking during the processing. The design of the blanking slot 7 facilitates the rapid removal of the PCB board main body 8 after the processing is completed, and is convenient for adjusting and adapting different widths and lengths of PCB board main bodies 8 of different sizes, maintaining the limited clamping of the PCB board main body 8, and facilitating the vertical stacking and limiting of the PCB board main body 8, thereby increasing the adaptability during production, and having a simple structure and strong size adaptability.
[0028] In order to increase the heat dissipation and signal isolation strength of the surface of the PCB board main body 8, a linear heat dissipation arc groove 9 is distributed in a linear array on the bottom surface of the PCB board main body 8, an isolation layer 10 is provided on the bottom surface of the PCB board main body 8, and a meridian arc groove 11 is evenly distributed in a linear array on the surface of the isolation layer 10. The design of the linear heat dissipation arc groove 9 and the meridian arc groove 11 increases the heat dissipation area and improves the heat dissipation efficiency of the PCB board main body 8. The isolation layer 10 and the meridian arc groove 11 on its surface provide additional electrical isolation, which increases the safety of the PCB board. The entire PCB board main body 8 adopts a stacked multi-layer design to achieve a more compact circuit layout and higher signal conduction efficiency, while taking into account stable heat dissipation. The isolation layer 10 effectively reduces the interference of electromagnetic radiation and maintains stable heat dissipation and signal transmission. Specific embodiment 2:
[0030] Reference Figure 1-5 In order to improve the heat dissipation of the PCB board body 8, the linear heat dissipation arc groove 9 and the meridian arc groove 11 are set to have the same groove width, the spacing between adjacent linear heat dissipation arc grooves 9 and the spacing between adjacent meridian arc grooves 11 are the same, and the groove width and spacing of the linear heat dissipation arc groove 9 and the meridian arc groove 11 are kept consistent, ensuring the uniformity of heat dissipation and isolation performance. The uniform groove width and spacing make the heat dissipation and isolation performance more stable and reliable, reducing performance fluctuations caused by design differences. Specific embodiment three:
[0032] Reference Figure 1-5 , the two ends of the adjacent warp splints 4 are located at the inner wall position of the weft splint 5, the inner walls of the warp splints 4 and the weft splints 5 are both against the side of the PCB board body 8, and the two ends of the warp splints 4 are located at the inner wall position of the weft splint 5, ensuring that when clamping, the warp splints 4 and the weft splints 5 can fit tightly with the side of the PCB board body 8 at the same time. This design makes the clamping more stable and further prevents the movement of the PCB board body 8 during the processing. The warp splints 4 and the weft splints 5 are the same in height and width. The surfaces of the warp splints 4 and the weft splints 5 are coated with an insulating coating. The same size ensures the interchangeability of the splints, simplifies the maintenance and replacement process, and the insulating coating improves the splints Electrical safety reduces the risk caused by leakage or short circuit. The isolation layer 10 is the same size as the PCB board body 8. An isolation layer 10 is connected between adjacent PCB board bodies 8. The uniform size ensures the perfect match between the isolation layer 10 and the PCB board body 8, and improves the isolation effect. The adjacent PCB board bodies 8 are connected by the isolation layer 10, which simplifies the installation and disassembly process. The size of the slot of the blanking slot 7 is smaller than the surface cross-sectional size of the PCB board body 8, which is convenient for the stacked PCB board body 8 to be lifted up and taken out through the bottom of the blanking slot 7. The bottom ends of the warp clamp 4 and the weft clamp 5 are respectively matched with the inner wall gaps of the L-shaped warp slot 2 and the L-shaped weft slot 3. Specific embodiment four:
[0034] Reference Figure 1-5 ,The surface of the PCB body 8 is provided with a plated hole 12. After the plated hole 12 is opened, the problem of residual rings on the hole edge can be effectively solved by optimizing the outer layer pattern compensation, such as Figure 5 As shown, by optimizing the outer layer pattern compensation, the problem of residual rings on the hole edges can be 100% eliminated.
[0035] In summary:
[0036] 1. The L-shaped warp groove 2 and the L-shaped weft groove 3 provided on the surface of the processing substrate 1 are used to cooperate with the warp clamp 4 and the weft clamp 5 to clamp the PCB board body 8, so as to facilitate the adjustment and adaptation of different widths and lengths of the PCB board bodies 8 of different sizes, maintain the limited clamping of the PCB board body 8, facilitate the stacking and limiting of the PCB board body 8 in the vertical direction, increase the adaptability during production, and have a simple structure and strong size adaptability;
[0037] 2. A linear heat dissipation arc groove 9 is set on the surface of the PCB board body 8 for surface heat dissipation, and an isolation layer 10 is added between adjacent PCB board bodies 8 for heat dissipation and isolation, so that the entire PCB board body 8 adopts a stacked multi-layer design to achieve a more compact circuit layout and higher signal conduction efficiency, while taking into account stable heat dissipation.
