Description

Technical Field

[0001] This utility model relates to the field of semiconductor equipment technology, specifically to a test board and test equipment. Background Technology

[0002] With the ever-shortening iteration cycles of electronic products, higher demands are being placed on the efficiency of reliability testing. High-acceleration life testing equipment, as core equipment for verifying product reliability, directly impacts product development and market launch progress. In the testing process, a frequently performed but often overlooked step is the installation and removal of the test board within the testing equipment. The test board is the carrier of the sample board under test; the reliability of the connection between the test board and the test chamber, the ease of installation and removal, and operational safety are fundamental to ensuring efficient and safe testing.

[0003] However, in traditional testing procedures, the installation and removal of test boards is often a time-consuming and cumbersome process. Existing test boards are generally placed directly inside the testing machine, lacking a dedicated assembly and disassembly mechanism. This design has several shortcomings. First, operators need to spend a significant amount of time and effort installing and removing the test boards, which not only increases workload but may also lead to operator fatigue, thus reducing work efficiency. Second, due to the lack of an effective fixing mechanism, the test board may slip during placement due to improper handling or other unexpected situations, causing damage. Damage to the test board not only delays the testing schedule but may also increase costs due to the need to prepare replacement test boards. Furthermore, due to the lack of an effective fixing and disassembly mechanism, the test board may loosen during testing. This loosening may lead to inaccurate test data, as even slight displacement of the test board can affect the accuracy of the test results. More seriously, in some cases, a loose test board may even damage the testing equipment, causing greater economic losses and safety hazards. Utility Model Content

[0004] In view of the problems existing in the prior art described above, this application provides a test board and test equipment, which can effectively prevent the test board body from loosening or slipping due to vibration during the test, and ensure the safety of the test process and the accuracy of the test data.

[0005] To achieve the above and other related objectives, this utility model provides a test board, comprising:

[0006] The main body of the test board, with the central area of ​​the test board being the sample placement area;

[0007] At least two opposing sliders are slidably disposed at both ends of the test plate body via grooves;

[0008] The disassembly and assembly assembly is mounted on the slide bar and located on one side of the test plate body, and is used to releasably lock the test plate body into the groove of the slide bar; the disassembly and assembly assembly includes an elastic element and a locking element, the elastic element being located on one side of the slide bar; the locking element is rotatably located at the end of the elastic element near the slide bar;

[0009] The locking component has a locked position and an unlocked position. When it is in the locked position, part of the locking component presses against the main body of the test board.

[0010] Optionally, the elastic element includes:

[0011] Support rod, installed on the side wall of the slider;

[0012] The connecting block is located at the end of the support rod furthest from the slide bar;

[0013] A torsion spring, one end of which is connected to the connecting block, and the other end extends in the direction of the slider.

[0014] Optionally, the disassembly and assembly components also include:

[0015] The L-shaped strip is connected at one end to the upper surface of the locking element. When the locking element is in the locked position, the other end of the L-shaped strip is slidably set on the upper surface of the slide bar.

[0016] Optionally, the disassembly and assembly components also include:

[0017] A limit strip is provided on the upper surface of the slide bar;

[0018] The limiting groove is set at the lower end of the L-shaped bar, corresponding to the limiting bar. When the locking member is in the locked position, the limiting groove is slidably set on the limiting bar along the length direction of the limiting bar.

[0019] Optionally, the test board body has multiple ventilation holes.

[0020] Alternatively, the shape of the ventilation opening may include circular, square, or oval.

[0021] Optionally, the test plate also includes a placement block disposed in the sample placement area.

[0022] In another aspect, this utility model provides a testing device, including a test board, which is the test board described above.

[0023] As described above, the test board and test equipment provided by this utility model have at least the following beneficial technical effects:

[0024] The test plate of this utility model includes a test plate body, at least two oppositely arranged slide bars, and a disassembly / assembly assembly. The central area of ​​the test plate body is the sample placement area. At least two oppositely arranged slide bars are slidably disposed at both ends of the test plate body via grooves. The disassembly / assembly assembly is disposed on the slide bars and located on one side of the test plate body, for releasably locking the test plate body in the groove of the slide bar; the disassembly / assembly assembly includes an elastic element and a locking element, the elastic element is disposed on one side of the slide bar, and the locking element is rotatably disposed at the end of the elastic element near the slide bar. The locking element has a locked position and an unlocked position; when in the locked position, a portion of the locking element presses against the test plate body.

[0025] This invention's test board, through its assembly and disassembly mechanism, achieves rapid locking and one-button release of the test board body within the sliding strip of the testing equipment. The assembly and disassembly mechanism utilizes a torsion spring-driven locking element, which springs back to the locked position after the test board body is inserted, reliably pressing the test board body firmly. This effectively prevents the test board body from loosening or slipping due to vibration during testing, fundamentally ensuring the safety of the testing process and the accuracy of the test data. Simultaneously, the sliding cooperation structure of the L-shaped strip and the limiting strip constitutes an effective anti-accidental opening mechanism, ensuring the stability of the locked state under extreme testing environments. Furthermore, this invention's test board replaces the traditional screw fixing method, eliminating the need for tools and making the replacement of the test board body simple and quick, significantly improving testing efficiency and greatly reducing the risk of sample board slippage and damage due to improper operation.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Although the illustrations only show components related to this utility model and are not drawn according to the actual number, shape and size of the components, the shape, quantity, positional relationship and proportion of each component can be arbitrarily changed under the premise of realizing the technical solution of this utility model, and the layout of the components may also be more complex.

[0033] Example 1

[0034] This embodiment provides a test board 2, as shown in the following example. Figures 1 to 3 The test board 2 includes a test board body 21, at least two oppositely arranged sliders 22, and a disassembly / assembly assembly 23.

[0035] Reference Figure 1 and Figure 2The central area of ​​the test plate body 21 is the sample placement area 211, which is used to place the sample plate to be tested. The design of the sample placement area 211 fully considers the size and shape of the sample plate to ensure that the sample plate can be stably placed on the test plate 2. Therefore, the size of the sample placement area 211 is not limited. For sample plates of different sizes, the size and shape of the sample placement area 211 can be adjusted accordingly to accommodate various types of sample plates, thereby ensuring the stable placement of the sample plate on the test plate 2. To further enhance the stability of the sample plate, placement blocks 2111 are provided on the sample placement area 211. These placement blocks 2111 not only support the sample plate but also accurately position it, ensuring that the sample plate will not move or shift during the test, thereby guaranteeing the accuracy and reliability of the test data. Preferably, the surface of the placement blocks 2111 is made of anti-slip material or processed with anti-slip texture to further enhance the stability of the sample plate. During the test, uniform heat distribution is crucial to ensuring the accuracy of the test results. Therefore, the test plate body 21 preferably has multiple ventilation holes 212. The design of the ventilation holes 212 ensures that heat is evenly distributed across the entire test plate 2 during testing. These ventilation holes 212 allow hot air to circulate smoothly, ensuring uniform heating of the sample plate. This design not only improves the accuracy of test results but also shortens testing time and increases testing efficiency. Furthermore, the size and spacing of the ventilation holes 212 are optimized to accommodate different types of sample plates and testing conditions. In this embodiment, the ventilation holes 212 may optionally be circular, square, or elliptical in shape to meet specific testing requirements. Due to the presence of the ventilation holes 212, the test plate 2 can better simulate the thermal conditions of the actual working environment, thus providing a more realistic testing environment for the sample plate.

[0036] Reference Figure 1 and Figure 2At least two opposing slide bars 22 are slidably disposed at both ends of the test plate body 21 via grooves. A disassembly / assembly assembly 23 is disposed on the slide bars 22 and located on one side of the test plate body 21, used to releasably lock the test plate body 21 into the grooves of the slide bars 22. The disassembly / assembly assembly 23 includes an elastic element 231 and a locking element 232. The elastic element 231 is disposed on one side of the slide bar 22. In this embodiment, the elastic element 231 includes a support rod 2311, a connecting block 2312, and a torsion spring 2313. The support rod 2311 serves as a basic support structure, with one end disposed on the side wall of the slide bar 22 and extending outward from the side wall of the slide bar 22, forming the mounting frame of the entire elastic element 231. The connecting block 2312 is disposed at the end of the support rod 2311 away from the slide bar 22. The torsion spring 2313 is the core elastic element of the elastic component 231. One end of the torsion spring 2313 is connected to the connecting block 2312, and the other end extends towards the direction of the slide bar 22. This installation method ensures that the torsion spring 2313 has a preload torque in its natural state that drives the relevant components to rotate in a certain direction. The locking component 232 is the direct functional component that performs locking and releasing actions. The locking component 232 is rotatably disposed at the end of the elastic component 231 near the slide bar 22. The locking component 232 has two working states: a locked position and an unlocked position. When in the locked position, part of the structure of the locking component 232 presses against the test plate body 21. During specific operation, when the operator needs to fix the test plate body 21, the locking component 232 will automatically reach or remain in the locked position under the driving torque of the elastic component 231. In this position, the locking element 232 presses against the side edge of the test board body 21, effectively preventing the test board body 21 from accidentally sliding out of the groove of the slide bar 22 through friction or mechanical interference. This achieves reliable locking of the test board body 21, ensuring its stability during the testing process and preventing it from loosening or falling off due to vibration or other external forces. This, in turn, ensures the accuracy of the test data and the safety of the testing process. Conversely, when it is necessary to replace or remove the test board body 21, the operator needs to apply an external force to the locking element 232, causing it to overcome the elastic restoring force of the torsion spring 2313 and rotate to the unlocked position. At this time, the pressing or locking relationship between the locking element 232 and the test board body 21 is released, and the test board body 21 can be smoothly pulled out of the groove of the slide bar 22. The entire disassembly process is simple and quick, which greatly improves the replacement efficiency of the test board body 21, reduces the workload of operators, and also reduces the risk of sample board damage caused by the cumbersome disassembly process, thus improving the operational safety and reliability of the test equipment.

[0037] Reference Figure 1 and Figure 2To further improve the reliability and guiding accuracy of the locking mechanism and prevent accidental disengagement, the disassembly assembly 23 also includes an L-shaped strip 233. One end of the L-shaped strip 233 is connected to the upper surface of the locking member 232. When the locking member 232 is in the locked position, the other end of the L-shaped strip 233 is slidably disposed on the upper surface of the slide bar 22. In this embodiment, the sliding of the L-shaped strip 233 is achieved through a limiting strip 234 and a limiting strip 2331. The limiting strip 234 is disposed on the upper surface of the slide bar 22. The limiting groove 2331 is disposed at the lower end of the L-shaped strip 233, corresponding to the limiting strip 234. When the locking member 232 is in the locked position, the limiting groove 2331 is slidably disposed on the limiting strip 234 along the length direction of the limiting strip 234. During the operation of the testing equipment, especially in environments with vibration or impact, the test plate body 21 may exert an outward pushing force on the locking member 232 in the locked position. In this embodiment, since the L-shaped strip 233 is set on the fixed limiting strip 234 through the limiting groove 2331, any force attempting to push the locking member 232 outward will be transmitted to the limiting strip 234 through the L-shaped strip 233. Because the limiting strip 234 is fixed, and the cooperation between the limiting groove 2331 and the limiting strip 234 restricts the outward movement freedom of the L-shaped strip 233, the pushing force is effectively resisted and dispersed, thereby ensuring the reliability of the locking member 232 in the locked state. Furthermore, the sliding cooperation between the limiting groove 2331 and the limiting strip 234 also allows the locking member 232 to smoothly slide into the locked position when inserted into the test plate body 21, even if it is squeezed by the edge of the test plate body 21. This is achieved through the sliding of the L-shaped strip 233 along the limiting strip 234 and the storage of force by the torsion spring 2313, providing a certain degree of adaptive tolerance.

[0038] Reference Figure 1 and Figure 2 The test plate 2 of this invention, through the installation and removal assembly 23, achieves rapid locking and instantaneous release of the test plate body 21 within the groove of the slide bar 22. The installation and removal assembly 23 uses a locking element 232 driven by a torsion spring 2313, which automatically resets to the locked position after the test plate body 21 is inserted, firmly pressing the test plate body 21 into the groove of the slide bar 22. This solves the problem of displacement or detachment of the test plate body 21 caused by equipment vibration during testing, providing a fundamental guarantee for the accuracy of test data and operational safety. Simultaneously, the sliding structure formed by the L-shaped strip 233 and the limiting strip 234 constructs a reliable anti-accidental opening protection mechanism, ensuring that the locked state remains stable even under harsh testing conditions. Furthermore, compared to traditional bolt connections, the test plate 2 of this embodiment eliminates the need for special tools, enabling quick manual replacement of the test plate body 21, significantly improving testing efficiency and effectively preventing the risk of sample plate drops due to operational errors.

[0039] Example 2

[0040] Reference Figures 1 to 3 The testing device 1 in this embodiment includes a test plate 2, which is the same as the test plate 2 described in Embodiment 1. In this embodiment, when testing the sample plate, the test plate 2 is fixedly mounted on the inner side wall of the testing device 1 by at least two opposing slide bars 22. The slide bars 22 not only provide stable support for the test plate body 21, but also enable the rapid installation and removal of the test plate body 21, greatly improving testing efficiency. When the operator needs to test the sample plate, the test plate body 21 is first inserted into the groove of the slide bar 22. Since the test plate body 21 and the groove of the slide bar 22 are connected by a sliding connection, the test plate body 21 can smoothly enter the interior of the testing device 1 under the guidance of the slide bar 22. This design not only simplifies the installation process of the test plate body 21, but also ensures the stability of the test plate body 21 during the testing process, avoiding the risk of sample plate damage due to improper installation. Furthermore, when the test board body 21 is inserted into the groove of the slide bar 22, the locking member 232 of the disassembly assembly 23 automatically enters the locking position under the action of the elastic member 231, firmly locking the test board body 21 in the groove of the slide bar 22. This automatic locking mechanism not only improves installation efficiency but also ensures safety during the testing process. Conversely, when it is necessary to replace or remove the test board body 21, the operator only needs to operate the locking member 232 to easily remove the test board body 21 from the slide bar 22; the entire process is quick and safe. The testing device 1 of this embodiment, through the ingenious design of the test board 2, achieves rapid installation and disassembly of the test board body 21, while ensuring stability and safety during the testing process. This design not only improves testing efficiency but also reduces the workload of operators, demonstrating significant technological advancement and practical value.
