Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging and testing board technology, specifically to a Toll packaging and testing board structure. Background Technology
[0002] In the field of semiconductor packaging and testing, Toll packaging technology is widely used because it can achieve high-density integration and improve chip performance. The corresponding packaging test board is the core carrier of the testing process and directly affects the testing accuracy and efficiency. However, with the continuous improvement of chip integration, the power consumption of the packaging test board increases significantly during the testing process. If the large amount of heat generated cannot be dissipated in time, it will cause the board temperature to rise sharply. This will not only interfere with the stability of the test signal, but may also damage the chip or test board components due to overheating, seriously affecting the accuracy of the test results and the service life of the equipment.
[0003] Currently, traditional Toll packaged test boards mostly use natural heat dissipation or simple air cooling. Natural heat dissipation relies on the heat conduction of the board itself, which has extremely low heat dissipation efficiency and is difficult to cope with high power consumption scenarios. Although air cooling accelerates airflow to remove heat through fans, the heat dissipation effect is still not ideal due to the low thermal conductivity of air. Moreover, the vibration generated by the fan during operation may interfere with precision testing.
[0004] For example, the existing technology disclosed in CN218099250U discloses a Toll packaged test board structure, including a base plate with three pins at the bottom and three internal transmission channels; a drain module with two drain pins and one drain contact; a gate module with one gate pin; and a source module with one source pin. The three pins are connected to the gate module, drain module, and source module respectively through the three transmission channels. The three transmission channels are connected to the drain contact, gate pin, and source pin respectively. A trench is provided between the source module and the drain module. The key technical point is that by using a Kelvin four-wire system, combined with the trench between the source and the gate, the interference caused by the impedance of the circuit itself on the accuracy of the test value can be effectively eliminated. It also increases the spacing between the pins, reduces the short circuit fault of the pins, and effectively limits the increase of leakage current between the source and the gate.
[0005] The large amount of heat generated during the test will cause the board temperature to rise sharply, which will not only interfere with the stability of the test signal, but also cause the results to deviate. Natural heat dissipation relies on the heat conduction of the board itself, which has extremely low heat dissipation efficiency.
[0006] To address these issues, we propose a novel Toll package test board structure. Utility Model Content
[0007] This invention provides a Toll packaged test board structure that solves the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0009] An embodiment of this utility model provides a Toll package test board structure, including: a base plate;
[0010] A cover plate, the bottom of which is disposed on top of a base plate;
[0011] The mounting base is configured in two sets, and the two mounting bases are rotatably connected by a rotating shaft;
[0012] A water-cooled plate is fixedly connected to the bottom of the base plate, and the interior of the water-cooled plate is hollow.
[0013] The heat dissipation component, installed at the bottom of the base plate, is used for water cooling of the packaged test board;
[0014] A fixing component, mounted on the outer side of the cover plate, is used to achieve the test of sealing.
[0015] Furthermore, the heat dissipation component includes a curved pipe, a water valve, and a water-cooled plate. Two holes are opened on the outer side of the water-cooled plate. The curved pipe is fixedly connected inside the water-cooled plate, and the inside of the curved pipe is hollow. A water valve is provided at one end of the curved pipe.
[0016] Through the above technical solutions, water cooling can more effectively help the test board dissipate heat and improve its service life.
[0017] Furthermore, a water pump is fixedly connected to the other end of the curved pipe, and an inlet is fixedly installed on the top of the water pump. The exterior of the water pump is located outside the base plate.
[0018] Through the above technical solution, the water pump is connected to the outside of the pipeline to realize the work of pumping water and achieving liquid exchange.
[0019] Furthermore, the bottom of the base plate is provided with heat dissipation holes, and the outer surface of the heat dissipation holes is circular, with the bottom of the heat dissipation holes abutting against the top of the water-cooling plate.
[0020] The above technical solution reduces the heat generated by the heat dissipation holes, which is beneficial for ventilation.
[0021] Furthermore, the fixing component includes a rotating shaft, a socket, a hook, and a short shaft. The outer side of the cover plate is rotatably connected to the outside of the rotating shaft, and the other side has a socket with an oblique opening. The inside of the socket is engaged with a hook, and the outside of the hook is fixedly connected to a short shaft.
[0022] The above technical solution allows the top cover to be snapped onto the base plate, avoiding interference during testing, and is simple and convenient.
[0023] Furthermore, both ends of the short shaft are rotatably connected to fixed seats, and the fixed seats are fixedly installed on the outside of the base plate. The hook is fixedly connected to a spring, and the end of the spring away from the hook is fixedly connected to the outside of the base plate.
[0024] The above technical solution allows pressing the hook to cause the spring to contract and extend, thus engaging the hook at the interface.
[0025] Furthermore, the top side of the base plate has multiple insertion holes arranged at equal intervals. The top end of the base plate away from the insertion holes is provided with multiple detection pins. The outer front ends of the insertion holes and detection pins are all fixedly connected with protrusions, and springs are fixedly connected to the outside of the protrusions.
[0026] With the above technical solution, when the test pin mounted on the top of the test board is inspecting the chip, the spring will contract to fix the chip in place.
[0027] The beneficial effects of this utility model are:
[0028] 1. The hollow water-cooled plate and internal curved pipes fixed at the bottom of the base plate, combined with the water pump driving the coolant circulation, can quickly absorb the heat generated by the test board during operation. Compared with traditional natural heat dissipation or air cooling, the heat conduction efficiency is higher, which can effectively avoid signal interference or component damage caused by overheating of the board. At the same time, the heat dissipation holes at the bottom of the base plate directly contact the water-cooled plate, further strengthening the heat conduction path and improving the uniformity of heat dissipation.
[0029] 2. The cover plate is rotatably connected to the mounting base via a pivot, and the other side is engaged with a hook via a beveled socket. The hook fits tightly into the socket with the help of the elasticity of the spring, forming a stable sealing structure. Compared with traditional bolt fastening, this design is more convenient to operate and avoids the problem of thread wear. Compared with simple snap-fit, the beveled socket combined with spring tension can effectively improve the sealing tightness and reduce the interference of external dust, moisture or airflow on the test contacts.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0036] like Figures 1 to 4 As shown, an embodiment of this utility model provides a Toll package test board structure, including: a base plate 1; a cover plate 2, the bottom of which is disposed on the top of the base plate 1; a mounting base 3, the outer side of which is configured as two sets, and the two mounting bases 3 are rotatably connected by a rotating shaft 4; a water-cooling plate 12, which is fixedly connected to the bottom of the base plate 1, and the interior of the water-cooling plate 12 is hollow; a heat dissipation assembly, which is installed on the bottom of the base plate 1 for water cooling of the package test board; and a fixing assembly, which is installed on the outer side of the cover plate 2 for achieving the sealing of the test.
[0037] In this embodiment, the cover plate 2 is rotatably connected to the mounting base 3 via the pivot 4, and can be opened and closed relative to the base plate 1. When closed, it is sealed by the fixing component, providing a stable environment for testing. The base plate 1 serves as a load-bearing foundation, and the water-cooled plate 12 integrated at the bottom works in conjunction with the heat dissipation component to solve the heat dissipation problem during testing. When the cover plate 2 is closed on the base plate 1, the hook 16 in the fixing component is inserted into the socket 15 of the cover plate 2, and the tension of the spring 18 makes the hook 16 fit tightly with the socket 15, thereby firmly fixing the cover plate 2 and the base plate 1 to form a sealed space and avoid external interference with the test.
[0038] like Figures 1 to 3 As shown, the heat dissipation assembly includes a curved pipe 10, a water valve 11, and a water-cooled plate 12. Two holes are opened on one side of the water-cooled plate 12. The curved pipe 10 is fixedly connected inside the water-cooled plate 12, and the inside of the curved pipe 10 is hollow. A water valve 11 is provided at one end of the curved pipe 10, and a water pump 14 is fixedly connected at the other end of the curved pipe 10. A water inlet 13 is fixedly installed on the top of the water pump 14. The water pump 14 is located outside the base plate 1. A heat dissipation hole 9 is opened at the bottom of the base plate 1, and the outside of the heat dissipation hole 9 is circular. The bottom of the heat dissipation hole 9 abuts against the top of the water-cooled plate 12.
[0039] In this embodiment, since the bottom of the heat dissipation hole 9 directly abuts against the top of the water-cooled plate 12, heat is quickly conducted from the heat dissipation hole 9 to the water-cooled plate 12, causing the water-cooled plate 12 to absorb heat and its temperature to rise. After the water pump 14 starts, it introduces external coolant through the water inlet 13 at the top and pressurizes and delivers the coolant to one end of the curved pipe 10. The curved pipe 10 is fixed inside the hollow water-cooled plate 12. Its tortuous structure increases the contact area with the water-cooled plate 12, and the hollow interior of the pipe can accommodate the flow of coolant. When the coolant flows in the curved pipe 10, it fully exchanges heat with the high-temperature water-cooled plate 12, absorbs the heat from the water-cooled plate 12, and its own temperature rises. After absorbing heat, the coolant flows out through the other end of the curved pipe 10. When it flows through the water valve 11, the flow rate of the coolant can be controlled by adjusting the opening and closing degree of the water valve 11, and finally it is discharged from the water-cooled plate 12, completing the heat dissipation cycle.
[0040] like Figures 1 to 4 As shown, the fixing assembly includes a rotating shaft 4, a socket 15, a hook 16, and a short shaft 19. The outer side of the cover plate 2 is rotatably connected to the outside of the rotating shaft 4, and the other side has a socket 15, which is oblique in shape. The hook 16 is snapped into the inside of the socket 15, and the short shaft 19 is fixedly connected to the outside of the hook 16. Both ends of the short shaft 19 are rotatably connected to a fixing seat 17, and the fixing seat 17 is fixedly installed on the outside of the base plate 1. A spring 18 is fixedly connected to the outside of the hook 16, and the end of the spring 18 away from the hook 16 is fixedly connected to the outside of the base plate 1. Multiple insertion holes 5 are opened on one side of the top of the base plate 1, and the multiple insertion holes 5 are arranged at equal intervals. Multiple detection pins 8 are provided at the top of the base plate 1 away from the insertion holes 5. The front ends of the insertion holes 5 and the detection pins 8 are fixedly connected to protrusions 6, and springs 7 are fixedly connected to the outside of the protrusions 6.
[0041] In this embodiment, the cover plate 2 is rotatably connected to the mounting base 3 via the pivot 4, and can be opened upward or closed downward around the pivot 4 to separate or fit with the base plate 1. When the cover plate 2 is closed, the oblique insertion port 15 on its outer side will contact the oblique surface of the hook 16. Since both the insertion port 15 and the hook 16 are obliquely designed, the hook 16 will slide along the oblique surface and be pushed open during the closing process. When the insertion port 15 completely passes the hook 16, the tension of the spring 18 causes the hook 16 to return to its original position and lock into the groove of the insertion port 15, forming a mechanical lock to ensure that the cover plate 2 fits tightly with the base plate 1. The tension of the spring 18 continues to act on the hook 16, keeping it in close contact with the insertion port 15 and preventing the cover plate 2 from loosening or warping. This elastic locking design can not only adapt to the wear caused by repeated opening and closing, but also compensate for the machining error of the parts and ensure a long-term stable sealing effect.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
