Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision circuit board technology, and in particular to a high-precision circuit board with multiple interfaces. Background Technology
[0002] While multi-interface circuit boards can connect more devices or connectors, they suffer from shortcomings in heat dissipation. This is because a multi-interface design requires more connectors and components to be arranged on the circuit board, and these connectors and components generate heat during operation. The dense interface leads to heat concentration in a limited space, increasing the difficulty of heat dissipation.
[0003] Complex wiring: The wiring of high-precision circuit boards is usually very complex, requiring careful design of line width, line spacing, and routing direction. Complex wiring can cause heat to accumulate in localized areas, making it difficult to dissipate. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to propose a multi-interface high-precision circuit board to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0006] To achieve the above objectives, one embodiment of the present invention provides a multi-interface high-precision circuit board, including a board body, positioning holes, and a pin assembly. Positioning holes are provided at the four corners of the board body, and a pin assembly is fixedly connected to the edge of the top surface of the board body.
[0007] A chip is installed in the middle of the top surface of the board;
[0008] Several first interfaces are installed at the other edge of the top surface of the plate, and the several first interfaces are arranged side by side as a group;
[0009] Several second interfaces are installed at the other edge of the top surface of the plate, and the several second interfaces are arranged side by side as a group;
[0010] The top surfaces of the first interface and the second interface are covered with conductive heat pipes, and the bottom surfaces of the conductive heat pipes are attached to the top surfaces of the first interface and the second interface through a layer of silicone grease.
[0011] The conductive tape descends after passing through the first interface and extends in a stepped manner to the top surface of the second interface;
[0012] The end of the heat-conducting tape extends above the plate, and a heat-collecting layer is fixedly connected to the end of the heat-conducting tape. The heat-collecting layer has several through holes arranged in a honeycomb pattern.
[0013] Preferably, in any of the above embodiments, the substrate of the plate is epoxy resin, and the top surface of the plate is covered with an insulating layer.
[0014] The above technical solution is adopted: This precision PCB circuit board consists of a board body, pin group, chip, various components on the board, multiple first interfaces, and multiple second interfaces.
[0015] The components on the board are fixed to the board body by first inserting pins and then soldering.
[0016] Preferably, of any of the above solutions, the first interface is a network port or a USB port, and the height of the first interface is greater than the height of the second interface.
[0017] Preferably, of any of the above solutions, the second interface is a TYPE-C port, and the material of the conductive tape is polyimide.
[0018] The above technical solution utilizes a circuit board with the following core structure: a heat-conducting tape, a silicone grease layer, a heat-collecting layer, and vias. First, the heat-conducting tape is attached extensively to the top surfaces of the first and second interfaces via the silicone grease layer. The heat-conducting tape is made of thermally conductive and insulating material. After passing the first interface, the tape descends and extends in a stepped fashion to the top surface of the second interface. Combined with the silicone grease layer, this effectively conducts away the heat generated when the first and second interfaces are mated with connectors. This design maximizes the capture of heat generated during connector mating. The heat is then uniformly conducted to the heat-collecting layer, which has several vias arranged in a honeycomb pattern. The heat-collecting layer has a large heat dissipation area, allowing fans to be placed above and below it. High-speed airflow quickly passes through the vias, enabling rapid heat dissipation from the heat-collecting layer and consequently, from the numerous first and second interfaces. This prevents the circuit board from overheating due to its multiple interfaces, resulting in excellent heat dissipation performance and preventing heat buildup. Through efficient heat conduction and heat dissipation design, heat on the circuit board is rapidly dissipated, avoiding heat accumulation. This helps reduce the temperature of the circuit board and improves the stability and reliability of the circuit. Good heat dissipation performance can ensure that the circuit board can work normally in high-temperature environments, thereby improving the performance and stability of the entire system.
[0019] Preferably, in any of the above embodiments, the heat collection layer is located on the side of the plate, the thickness of the heat collection layer is greater than the thickness of the heat conduction cable, and the material of the heat collection layer is polyimide.
[0020] Preferably, the through hole is a regular hexagon in shape, as described in any of the above schemes.
[0021] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0022] This high-precision multi-interface circuit board utilizes a combination of heat-conducting tape, silicone grease layer, heat-collecting layer, and vias. The heat-conducting tape, made of thermally conductive and insulating material, adheres extensively to the top surfaces of the first and second interfaces via the silicone grease layer. After passing the first interface, the tape descends in a stepped fashion to the top surface of the second interface. Together with the silicone grease layer, it effectively conducts away the heat generated when the first and second interfaces mate with the connectors. This design maximizes the capture of heat generated during connector mating. The heat is then uniformly directed to the heat-collecting layer, which features several vias arranged in a honeycomb pattern. The large heat dissipation area of the heat-collecting layer allows for the placement of fans above and below it, enabling high-speed airflow through the vias for rapid heat dissipation. This, in turn, facilitates rapid heat dissipation from the numerous first and second interfaces, preventing the entire multi-interface circuit board from overheating. This efficient heat conduction and dissipation design ensures that heat on the circuit board is quickly dissipated, preventing heat buildup. This contributes to lowering the circuit board's temperature and improving circuit stability and reliability. Good heat dissipation performance can ensure that the circuit board can work normally in high-temperature environments, thereby improving the performance and stability of the entire system.

High-speed airflow quickly passes through the through-holes 10, enabling rapid heat dissipation from the heat-collecting layer 9 and consequently, from the numerous first interfaces 5 and the second interface 6. This prevents the multi-interface circuit board from overheating, resulting in excellent heat dissipation performance, minimal heat accumulation, and effective prevention of heat buildup. Through efficient heat conduction and heat dissipation design, heat on the circuit board can be quickly dissipated, preventing heat buildup. This helps reduce the circuit board temperature, improving circuit stability and reliability. Good heat dissipation performance ensures the circuit board can operate normally in high-temperature environments, thereby enhancing the performance and stability of the entire system.
