[0002] In today's era of rapid technological advancement, electronic products are experiencing explosive growth. From smartphones and tablets to wearable devices and high-speed communication base stations, these electronic products are constantly evolving towards smaller size, more powerful functions, and higher performance. HDI (High-Intensity Distributed) circuit boards have emerged in response to this trend and their applications are rapidly expanding. Their higher wiring density and smaller apertures allow for more compact integration of electronic components, a key factor in meeting the miniaturization and high-performance demands of modern electronic products.

[0003] Traditional PCB stack-up assemblies often lack precise mounting structures specifically designed for HDI PCBs. For example, there are no mounting slots or positioning marks of specific shapes and sizes, which means that when placing PCBs into the stack-up assembly, positioning often relies solely on the operator's experience and rough measuring tools.

[0005] This utility model is achieved by the following technical solution: an HDI circuit board stacking device, including a stacking plate, an HDI circuit board mounting groove is provided in the middle of the upper surface of the stacking plate, connecting plates are fixedly connected to both sides of the stacking plate, mounting holes are provided on both sides of the upper surface of the connecting plate, and a fixing seat is fixedly connected to the bottom of the connecting plate.

[0006] The above technical solution enables HDI circuit boards to have dedicated installation locations, facilitating the installation and positioning of the circuit boards. The connecting plates and mounting brackets on both sides can construct a stable structure, providing a foundation for subsequent connection and fixing operations.

[0007] As a further improvement to the above solution, the upper and lower surfaces of the fixing base are both fixedly connected with locking blocks, which are adapted to the mounting holes.

[0008] The above technical solution provides a simple and effective matching structure between the card block and the mounting hole, which facilitates the assembly of components, eliminates the need for complex connection processes, reduces assembly costs, and ensures the accuracy of the connection to a certain extent.

[0009] As a further improvement to the above solution, connection holes are provided on both sides of the inner wall of the card block.

[0010] Through the above technical solution, the connection holes opened on both sides of the inner wall of the card block provide connection channels for subsequent connecting components, so that further fastening or connection can be carried out through these connection holes.

[0011] As a further improvement to the above solution, a threaded sleeve is fitted onto the inner wall of the connecting hole.

[0012] The above technical solution uses a threaded connection, which is firm and easy to adjust. The threaded sleeve can be screwed in or out of the connection hole as needed, which facilitates fine-tuning of the device or adapting to different assembly requirements.

[0013] As a further improvement to the above solution, the bottom of the threaded sleeve is fixedly connected with a first fastening bolt.

[0014] Through the above technical solution, the first fastening bolt enhances the stability of the threaded sleeve connection, prevents the threaded sleeve from loosening during use, and ensures the reliability of the overall structure of the device.

[0015] As a further improvement to the above solution, the inner wall of the threaded sleeve is fixedly connected to a threaded rod by a thread, and the top of the threaded rod is fixedly connected to a second fastening bolt.

[0016] Through the above technical solution, the combined structure of the threaded sleeve and the threaded rod increases the device's vertical adjustment capability, allowing for adjustment of height or tightness according to actual needs, thus improving the device's adaptability to different HDI circuit board stack-up requirements.

An HDI circuit board mounting groove 2 is formed in the center of the upper surface of the stacking plate 1. Connecting plates 3 are fixedly connected to both sides of the stacking plate 1. Mounting holes 4 are formed on both sides of the upper surface of the connecting plates 3. A fixing seat 5 is fixedly connected to the bottom of the connecting plates 3. The stacking plate 1 is the basic structure of the entire device. The HDI circuit board mounting groove 2 in the center of its upper surface is used to place the HDI circuit board. The connecting plates 3 on both sides are used to connect other components or for fixing operations. The mounting holes 4 on both sides of the upper surface of the connecting plates 3 provide connection positions, and the fixing seat 5 at the bottom provides support and connection.

[0028] Both sides of the upper and lower surfaces of the fixed base 5 are fixedly connected with locking blocks 6. The locking blocks 6 are adapted to the mounting holes 4. The locking blocks 6 on both sides of the upper and lower surfaces of the fixed base 5 are adapted to the mounting holes 4 on the connecting plate 3. This allows the fixed base 5 and the connecting plate 3 to be connected through the cooperation of the locking blocks 6 and the mounting holes 4, ensuring the integrity and stability of the structure.

[0029] Connection holes 7 are provided on both sides of the inner wall of the card block 6. The connection holes 7 on both sides of the inner wall of the card block 6 provide connection channels for subsequent connecting components, so that further fastening or connection operations can be performed through these connection holes 7.

[0030] A threaded sleeve 8 is fitted onto the inner wall of the connecting hole 7. The threaded sleeve 8 is fitted onto the inner wall of the connecting hole 7. The external thread of the threaded sleeve 8 is engaged with the inner wall of the connecting hole 7 to achieve the positioning and fixation of the threaded sleeve 8 in the connecting hole 7.

[0031] The bottom of the threaded sleeve 8 is fixedly connected to a first fastening bolt 9. The position of the threaded sleeve 8 can be further fixed by tightening the first fastening bolt 9.

[0032] The inner wall of the threaded sleeve 8 is fixedly connected to a threaded rod 10 by threads. The top of the threaded rod 10 is fixedly connected to a second fastening bolt 11. The threaded rod 10, which is fixedly connected to the inner wall of the threaded sleeve 8 by threads, can move up and down within the threaded sleeve 8 by the interaction between the threads. It can be fastened or connected by the second fastening bolt 11 at the top.

[0033] The implementation principle of an HDI circuit board stacking device in this application embodiment is as follows: The HDI circuit board is initially positioned and placed through the HDI circuit board mounting groove 2 in the middle of the upper surface of the stacking board 1. The connecting plates 3 on both sides of the stacking board 1 are used to expand the connection structure. The mounting holes 4 on both sides of the upper surface of the connecting plate 3 provide interfaces for subsequent connections. The fixing seat 5 is connected to the connecting plate 3 through the locking blocks 6 on its upper and lower surfaces that are adapted to the mounting holes 4. This cooperation between the locking blocks 6 and the mounting holes 4 determines the positional relationship of the fixing seat 5 relative to the connecting plate 3 and the stacking board 1, thereby constructing the basic framework structure of the device and providing a stable support structure for the installation of the HDI circuit board. The connecting holes 7 opened on both sides of the inner wall of the locking blocks 6 provide the possibility for further component connections. The threaded sleeve rod 8 is fitted into the wall. The inner diameter of the connecting hole 7 and the outer diameter of the threaded sleeve rod 8 are used to position the threaded sleeve rod 8 on the clamping block 6. The first fastening bolt 9 at the bottom of the threaded sleeve rod 8 can be used to further fix the threaded sleeve rod 8 in the connecting hole 7 to prevent it from loosening or displacing. The inner wall of the threaded sleeve rod 8 is fixedly connected to the threaded rod 10 by threads. This threaded connection allows the threaded rod 10 to rotate within the threaded sleeve rod 8, thereby realizing the up and down movement of the threaded rod 10 relative to the threaded sleeve rod 8. The second fastening bolt 11 at the top of the threaded rod 10 can be used to tighten it after the threaded rod 10 is adjusted to a suitable position to maintain the stability of the entire structure. Through this connection method, the height of the device or other related parameters can be flexibly adjusted according to actual needs.
