The bottom of the connecting base has an adapter mounting groove, and a protective connecting frame is fixedly installed in the middle of the top wall of the adapter mounting groove. Battery packs are provided on both sides of the protective connecting frame. A contact switch socket and a contact switch plug are provided on one side of each battery pack. Miniature air pumps are provided on both the front and back of the battery packs, and air guide pipes are fixedly installed at the outlets of the miniature air pumps. This invention uses miniature air pumps to create negative pressure inside the ventilation cavity and the protective connecting frame, thereby fixing the chip and the entire tray to the chip testing platform. The overall structure is simple and easy to operate, greatly ensuring the stability of the entire tray during chip testing and preventing the chip tray body from shaking, which could affect the chip testing process.

[0003] This type of chip testing tray is automatically powered on and adsorbed when placed. It is not convenient to adjust the position of the chip during the testing process. The testing components may come into contact with the chip surface during the testing process. The stability of adsorption by negative pressure alone is poor. In addition, the chip may get stuck in the slot during the negative pressure adsorption process of the air pump, and it is not easy to remove it after the test is completed.

[0004] To address the aforementioned issues, we have made improvements by proposing a chip testing tray that is easy to secure. Utility Model Content

[0030] Example: Figure 1-6 As shown, a chip testing tray that is easy to fix includes a testing tray 1, and an anti-interference board 14 is provided inside the testing tray 1;

[0031] The anti-interference plate 14 has several placement slots 2, and a central ring 8 is provided inside the placement slot 2. A vacuum groove is formed inside the central ring 8, and a ventilation hole 11 is provided at the bottom of the vacuum groove. A heightening member 6 is provided extending from the edge of the central ring 8 to the edge of the placement slot 2.

[0032] A clamping block 7 is provided at the edge of the placement slot 2;

[0033] The edge of the detection tray 1 is provided with a groove 4, and a base 3 is slidably connected in the groove 4. An extension rod 5 is provided on the top of the base 3.

[0034] The extension rod 5 is generally U-shaped, and a ball screw 19 is installed at the end of the extension rod 5. A pressure plate 20 is installed at the end of the ball screw 19.

[0035] A miniature air pump 16 is installed at the bottom of the test tray 1. The miniature air pump 16 is externally connected to an air pipe 15. The end of the air pipe 15 is connected to the inside of the vacuum chamber of the central ring 8.

[0036] The extension part 6 and the center ring 8 are made of liquid silicone. The extension part 6 and the center ring 8 are integrally molded structures. Several anti-slip protrusions 12 are evenly distributed on the upper surface of the extension part 6, and a sealing ring 13 is provided on the upper surface of the center ring 8.

[0037] The central ring 8 limits the area of ​​the vacuum groove, making it easy to place chips of various sizes and models on the tray, while avoiding squeezing the sides of the chips. When the chip is placed on top of the center 8, the edge of the chip contacts the raised part 6. The adsorption force of the liquid silicone can reduce the movement of the chip during the detection process, and the negative pressure adsorption maintains the stability of the chip.

[0038] The clamping block 7 is hinged to the anti-interference board 14 by a torsion spring. When the chip size is large, the clamping block 7 on the side will press down and fix the chip edge, improving the adaptability of the tray.

[0039] The front of the test tray 1 is provided with a reserved groove 10 that communicates with the slide 4. The width of the reserved groove 10 is the same as the outer diameter of the base 3. A spring 17 is installed on the inner bottom surface of the base 3. The bottom of the spring 17 is connected to the extension rod 5.

[0040] The extension rod 5 is inserted into the base 3 and slidably connected to the base 3. The end of the extension rod 5 is rotatably mounted with a connector 18, and the connector 18 is equipped with a nut assembly that matches the ball screw 19.

[0041] The bottom of the pressure plate 20 is equipped with a non-marking adhesive plate.

[0042] The height of the pressure plate 20 is adjusted by pulling the ball screw 19. During the process of pulling the ball screw 19, the connector 18 rotates, adjusting the extension length of the ball screw 19. When the extension rod 5 is pressed down, the spring 17 is compressed, so that the lower part of the pressure plate 20 contacts the chip. Maintaining the downward pressure can maintain the stability of the chip detection process. After the downward pressure is removed, the traceless adhesive under the pressure plate 20 will stick the chip up, making it easy to remove the chip.

[0043] The upper part of the test tray 1 is equipped with a control button 9 that is electrically connected to the micro air pump 16.

[0044] Working Principle: This easy-to-fix chip testing tray, when in use, places the chip on the central ring 8. The central ring 8 limits the area of ​​the vacuum groove, making it easy to place chips of various sizes and models on the tray, while avoiding compression of the chip's sides. When the chip is placed on top of the central ring 8, the chip's edge contacts the lifting part 6. The adsorption force of the liquid silicone reduces chip movement during the testing process. Combined with negative pressure adsorption, it maintains the chip's stability. The height of the pressure plate 20 is adjusted by pulling the ball screw 19. During the pulling of the ball screw 19, the connecting part 18 rotates, adjusting the extension length of the ball screw 19. When the extension rod 5 is pressed down, the spring 17 is compressed, so that the lower part of the pressure plate 20 contacts the chip. Maintaining the downward pressure helps maintain the stability of the chip during the testing process. After the downward pressure is removed, the residue-free adhesive under the pressure plate 20 picks up the chip, making it easy to remove.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
