[0001] This application relates to the field of integrated circuit testing technology, and in particular to an ATE board clamp. Background Technology
[0002] Integrated circuit testing is a crucial link in the integrated circuit industry chain and a key factor in ensuring the performance and quality of integrated circuits. Automatic Test Equipment (ATE) is an indispensable tool for integrated circuit testing. The printed circuit board used in ATE to test the integrated circuit under test is called the "ATE board." Therefore, to ensure the quality of subsequent integrated circuit testing, the quality inspection of the ATE board is extremely important.
[0003] In related technologies, the ATE board needs to be fixed on the testing equipment before it can be tested. However, since ATE boards vary in shape and size, there is a strong correlation between the ATE board and the fixture used to fix it. This means that when testing different ATE boards, the corresponding fixture needs to be changed simultaneously for each ATE board, resulting in low testing efficiency. Utility Model Content
[0004] The purpose of this application is to provide an ATE board fixture to improve the testing efficiency of ATE boards. The specific technical solution is as follows:
[0005] This utility model provides an ATE board clamp, including a frame 110, a sliding rod 120, and a fixing clamp 130;
[0006] The frame 110 includes a first hollow rod 111, a second hollow rod 112, and a third hollow rod 113; one end of the sliding rod 120 is slidably connected to the first hollow rod 111, and the other end of the sliding rod 120 is slidably connected to the third hollow rod 113; wherein, the first hollow rod 111 and the third hollow rod 113 are parallel.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] ATE boards are key tools in the semiconductor industry for chip testing. They are primarily used to perform comprehensive functional, performance, and reliability testing on semiconductor chips, characterized by high precision, high density, and stringent reliability requirements. Therefore, obtaining high-quality ATE boards is crucial in the chip manufacturing process.
[0024] In related technologies, when inspecting ATE boards, a fixture is first used to fix the ATE board in place. However, in order to match ATE boards of different shapes and sizes, the ATE board fixtures often have different shapes and sizes. Consequently, if different ATE boards need to be inspected, the ATE board fixture matching the ATE board to be inspected needs to be changed simultaneously, which results in low inspection efficiency for ATE boards.
[0025] To address the above problems, this utility model provides an ATE board clamp, such as... Figure 1 As shown, it may include: frame 110, sliding rod 120, and fixing clip 130;
[0026] The frame 110 includes a first hollow rod 111, a second hollow rod 112 and a third hollow rod 113; one end of the sliding rod 120 is slidably connected to the first hollow rod, and the other end of the sliding rod 120 is slidably connected to the third hollow rod 113; wherein, the first hollow rod and the third hollow rod 113 are parallel.
[0027] The fixing clip 130 is fixed to the sliding rod 120 and the frame 110; wherein, the fixing clip 130 fixed to the frame 110 is located on the same side of the sliding rod 120;
[0028] The fixing clamp 130 includes a fixing plate and a rotating plate; the rotating plate is rotatably connected to the fixing plate; wherein the ATE board to be tested is clamped in the area enclosed by the rotating plates of each fixing clamp 130.
[0029] The ATE board clamp provided in this embodiment of the utility model can change the size and shape that the ATE board clamp can clamp by adjusting the position of the sliding rod and rotating the direction of the rotating plate on the fixed clamp. This allows the same ATE board clamp to be adapted to ATE boards of different sizes and shapes. Therefore, during the ATE board testing process, even if different ATE boards are replaced, there is no need to replace the ATE board clamp, thereby saving the time of replacing the ATE board clamp during the testing process and improving the testing efficiency of ATE boards.
[0030] Reference Figure 1 This utility model embodiment provides a detailed description of the ATE board fixture.
[0031] The frame 110 may include a first hollow rod 111, a second hollow rod 112, and a third hollow rod 113. The hollow rods may be support rods with hollowed-out grooves; the first hollow rod 111 and the third hollow rod 113 are parallel to each other.
[0032] In one feasible implementation, the frame can be a right-angled U-shape. The two ends of the second hollow rod are fixed to one end of the first hollow rod and one end of the third hollow rod, respectively. Furthermore, the second hollow rod is perpendicular to both the first and third hollow rods.
[0033] In another possible approach, refer to Figure 1 The frame 110 may also include a regular rod 140, meaning the entire frame 110 can be a rectangular structure. The regular rod 140, the first hollow rod 111, the second hollow rod 112, and the third hollow rod 113 are connected end-to-end and vertically fixed.
[0034] The sliding rod 120 can be slidably connected to the frame 110. One end of the sliding rod 120 is slidably connected to the first hollow rod 111, and the other end of the sliding rod 120 can be slidably connected to the third hollow rod 113.
[0035] The ATE board fixture may also include a rotating screw 300. The sliding rod 120 can be slidably connected to the first hollow rod 111 and the third hollow rod 113 via the rotating screw 300. When the rotating screw 300 is tightened, the sliding rod 120 is relatively fixed to the frame 110, that is, the first hollow rod 111 and the third hollow rod 113; when the rotating screw 300 is loosened, the sliding rod 120 can slide relative to the frame 110.
[0036] In a possible implementation, the aspect ratio of the rectangular frame can be 3:2. Specifically, the length of the rectangular frame can be 60 cm and the width can be 40 cm. That is, the lengths of the first hollow rod 111 and the third hollow rod 113 are 40 cm; the lengths of the ordinary rod 140 and the second hollow rod 112 are 60 cm. In this implementation, the length of the sliding rod also needs to be not less than 60 cm so that the sliding rod 120 can be slidably connected between the first hollow rod 111 and the third hollow rod 113. To reserve the installation position for the fixing clip, in this embodiment, the slidable length of the sliding rod 120 along the top-to-bottom direction of the first hollow rod 111 and the third hollow rod 113 can be 0 - 35 cm.
[0037] The fixing clip 130 is fixed on the sliding rod 120 and the frame 110, and the fixing clip 130 fixed on the frame 110 is located on the same side of the sliding rod 120. Refer to Figure 1 , the sliding rod 120 and the rectangular frame 110 form a "day" - shaped structure, where the fixing clip 130 is located on the frame 110 distributed in the lower part of the "day" - shaped structure.
[0038] In a possible implementation, refer to Figure 1 , in the embodiment of the present utility model, the ATE board fixture may include 6 fixing clips 130. Among them, the first fixing clip and the second fixing clip may be fixed on the sliding rod 120; the third fixing clip may be fixed on the first hollow rod; the fourth fixing clip and the fifth fixing clip may be fixed on the second hollow rod 112; the sixth fixing clip may be fixed on the third hollow rod 113.
[0039] The first fixing clip, the second fixing clip, the fourth fixing clip, and the fifth fixing clip may be evenly distributed on the sliding rod and the second hollow rod. Referring to the structure of the frame in the foregoing embodiment, the distance between the first fixing clip and the second fixing clip may be 20 cm. The first fixing clip and the second fixing clip may be respectively fixed on the sliding rod 20 cm away from the first hollow rod and the third hollow rod; the distance between the fourth fixing clip and the fifth fixing clip may be 20 cm. The fourth fixing clip and the fifth fixing clip may be respectively fixed on the second hollow rod 20 cm away from the first hollow rod and the third hollow rod. The positions of the third fixing clip and the sixth fixing clip may be set according to the sliding range of the sliding rod. For example, the third fixing clip may be fixed on the first hollow rod 5 cm away from the second hollow rod; the sixth fixing clip may be fixed on the third hollow rod 5 cm away from the second hollow rod. More cases are not listed one by one in this embodiment.
[0040] In another possible implementation, refer to Figure 2 , the ATE board fixture may also include 4 fixing clips, and one fixing clip may be provided on each of the sliding rod, the first hollow rod, the second hollow rod, and the third hollow rod.
[0041] Each of the hollowed-out rods and sliding rods of this utility model is equipped with a fixing clip. When clamping the ATE board, the ATE board to be tested can be clamped from multiple directions using at least three fixing clips. In this way, this utility model can achieve multi-point clamping of the ATE board at least three points. Compared with the existing ATE board clamps, which can only use two-point fixing to clamp the ATE board at a time, this utility model can clamp the ATE board to be tested more stably, reduce the probability of displacement of the ATE board during the testing process, and improve the stability of the ATE board.
[0042] The fixing clip 130 may include a fixing plate and a rotating plate. The fixing plate and the rotating plate may be a combination shape composed of rectangles and triangles.
[0043] like Figure 3a As shown, the shape of the fixed plate 301 can be composed of a rectangle and an isosceles triangle with a base length less than the length of the long side of the rectangle; the shape of the rotating plate 302 can be composed of a rectangle and an isosceles triangle with a base length equal to the length of the long side of the rectangle.
[0044] like Figure 3b As shown, the shape of the fixed plate 303 can be composed of a rectangle and an isosceles triangle with a base length equal to the length of the long side of the rectangle; the shape of the rotating plate 304 can be composed of a rectangle and an isosceles triangle with a base length equal to the length of the long side of the rectangle.
[0045] The fixed plate and the rotating plate can be connected by rotating a screw. (See reference) Figure 3a , Figure 3b The rotating screw 300 connects the fixed plate and the rotating plate. Tightening the rotating screw 300 prevents the fixed plate and the rotating plate from rotating relative to each other; loosening the rotating screw 300 allows the fixed plate and the rotating plate to rotate relative to each other. The rotation range of the rotating plate, or in other words, the side of the rotating plate that contacts the ATE board to be tested during rotation, is always within the closed area formed by the sliding rod and the frame.
[0046] When the ATE board to be tested is circular or near-circular, three clamps can be selected to secure the ATE board. For example... Figure 4 As shown, by adjusting the position of the sliding rod 410 and the angle between it and the rotating plates on the fixing clamps 420, 430, and 440, the near-circular ATE board can be clamped. Furthermore, this embodiment can also utilize the remaining three empty fixing clamps on the fixture to clamp a second ATE board, improving fixture utilization and thus enabling the testing of two ATE boards using a single fixture, thereby increasing testing efficiency.
[0047] When the ATE board to be tested is a rectangular board, four fixing clips can be selected, for example, four fixing clips fixed on the sliding rod and the second hollow rod, to clamp it and improve stability.
[0048] In this embodiment of the invention, the material of the side of the rotating plate that contacts the ATE board to be tested can be an alloy material.
[0049] This utility model embodiment utilizes a sliding rod that can slide along the frame to adjust the size of the ATE board clamp; by rotating the direction of the rotating plate on the fixed clamp, the clamping range of the ATE board clamp is adjusted; this utility model embodiment provides an ATE board clamp that can be adapted to the ATE board to be tested, so that during the testing process, only one ATE board clamp can be used to clamp ATE boards of different sizes and shapes, without having to repeatedly change different ATE board clamps, thus improving the testing efficiency of ATE boards.
[0050] Furthermore, the ATE board fixture provided in this embodiment of the present invention can achieve one-to-many adaptation between the fixture and the ATE board. Thus, there is no need to design different ATE board fixtures for different ATE boards, which greatly reduces the number of ATE fixtures and achieves the purpose of reducing testing costs and speeding up the testing process.
