Description

Technical Field

[0001] This utility model belongs to the field of dye penetration testing technology, specifically a dye penetration testing tank for chip packaging cracks. Background Technology

[0002] In the chip packaging process, verifying the absence of leaks is a crucial step. Its core purpose is to ensure that the internal circuitry of the chip can be effectively isolated from the external environment (such as moisture, dust, corrosive gases, etc.), thereby ensuring the chip's stable performance and lifespan. To achieve this verification, the industry commonly uses a method of placing the chip in a dye penetrant testing tank and immersing it in the dye penetrant liquid in the tank. Through thorough immersion, the liquid can leave penetration marks at the defects in the chip packaging. This provides a direct basis for accurately locating potential problems such as cracks, pinholes, and gaps caused by loose bonding wires that may occur during the subsequent packaging process, greatly improving the accuracy and efficiency of the test.

[0003] However, existing dye penetration testing tanks pose significant environmental risks in practical use. During operation, a fixed amount of dye penetration solution must be added to the testing tank before the chip is placed inside. The liquid is then heated using a heating device to accelerate its penetration into the chip. However, during this process, the dye penetration solution generates some water vapor due to heating. Moreover, most testing tanks are open-type designs, which directly cause water vapor to carry some of the dye penetration solution into the air. These volatiles not only pollute the surrounding air quality but may also harm the health of operators in the long term. Furthermore, they do not meet the requirements of environmentally friendly production. Therefore, a dye penetration testing tank for chip packaging cracks is proposed to address the above problems.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5This utility model provides a chip packaging crack staining penetrant detection tank, including a penetrant detection shell 1; the top of the penetrant detection shell 1 is in contact with a sealing cover plate 2, the middle of the sealing cover plate 2 is fixedly connected to an exhaust pipe 3, the middle of the exhaust pipe 3 is provided with a sliding groove 10, the middle of the sliding groove 10 is slidably connected to a moving block 45, the middle of the moving block 45 is equipped with an activated carbon adsorption plate 4, the outer wall of the activated carbon adsorption plate 4 slides in the middle of the exhaust pipe 3, the top of the exhaust pipe 3 is fixedly connected to a fixing shell 42, and the top of the fixing shell 42 is slidably connected to a pull rod 41. A fixed column 48 is fixedly connected to the top of the movable block 45, and the bottom of the pull rod 41 is rotatably connected to the top of the fixed column 48. A plug-in block 47 is fixedly connected to the middle of the movable block 45. A plug-in groove 44 is opened at the edge of the top of the activated carbon adsorption plate 4, and the plug-in block 47 is inserted into the middle of the plug-in groove 44. During operation, when dyeing penetration testing is required, the product can be placed in the middle of the penetration testing shell 1, and the dyeing penetration solution can be poured into it. Then, the sealing cover plate 2 is placed on the top of the penetration testing shell 1, so that the penetration testing shell 1 can be placed on the heating device for further processing. Heating is performed to improve the penetration effect. During the heating process, the dyeing permeation solution boils, and the water vapor produced by boiling is discharged through the exhaust pipe 3. During the discharge process, the water vapor needs to pass through the activated carbon adsorption plate 4. The activated carbon adsorption plate 4 adsorbs harmful substances in the water vapor, reducing the risk of water vapor posing a hazard to the outside air. When the activated carbon adsorption plate 4 needs to be replaced after a period of use, the pull rod 41 can be pulled. The pull rod 41 will drive the moving block 45 to move through the fixed column 48, moving it to the middle of the fixed shell 42. When the activated carbon adsorption plate 4 moves out from the middle of the exhaust pipe 3, directly push the activated carbon adsorption plate 4 to make the plug block 47 disengage from the middle of the plug groove 44. In this way, the activated carbon adsorption plate 4 can be removed. When installing, directly insert the activated carbon adsorption plate 4 into the middle of the moving block 45. During the insertion process, ensure that the plug block 47 can be smoothly inserted into the middle of the plug groove 44 until the plug block 47 is fully inserted into the middle of the plug groove 44. At this time, push the reverse push rod 41 to move the activated carbon adsorption plate 4 to the middle of the exhaust pipe 3.

[0026] Furthermore, such as Figures 1-3As shown, the top of the sealing cover plate 2 has a sliding groove 9, and a push block 5 is slidably connected to the middle of the sliding groove 9. A connecting plate 51 is rotatably connected to the bottom of the push block 5. A limiting plate 53 is slidably connected through the outer wall of the sealing cover plate 2. The top outer wall of the permeation detection shell 1 has a rectangular groove 6, and the end of the limiting plate 53 is inserted into the middle of the rectangular groove 6. A rotating rod 52 is rotatably connected to the top of the limiting plate 53, and the top of the rotating rod 52 is fixed to the bottom side of the end of the connecting plate 51. A second spring 54 is fixed to the side wall of the bottom of the push block 5, and the other end of the second spring 54 is fixed to the middle of the sliding groove 9. During operation, when the permeation detection shell 1 and the sealing cover plate 2 are combined, the sealing cover plate 2 can be directly put on the top of the permeation detection shell 1. During the fitting process, the limiting plate 53 will interact with the permeation detection shell 1. When the permeation detection housing 1 contacts the rectangular groove 6, the housing 1 will push the limiting plate 53 along the inclined surface of the limiting plate 53 to move. The limiting plate 53 will rotate with the rotating rod 52, and drive the rotating rod 52 to move. The rotating rod 52 will change the angle of the connecting plate 51, and at the same time, the other end of the connecting plate 51 will rotate with the push block 5, and drive the push block 5 to slide in the middle of the slide groove 9 until the limiting plate 53 coincides with the rectangular groove 6. At this time, the limiting plate 53 can be reset and inserted in the middle of the rectangular groove 6 to limit the sealing cover 2. In this way, the permeation detection housing 1 and the sealing cover 2 will be stably combined together. When disassembling, simply push the push block 5. The subsequent structural movement is the same as above, until the limiting plate 53 is disengaged from the middle of the rectangular groove 6, and the sealing cover 2 can be removed. It is quick and convenient.

[0027] Furthermore, such as Figure 2 As shown, a sealing ring 8 is fixedly connected to the middle of the sealing cover plate 2, and a sealing groove 7 is opened on the top of the permeation detection shell 1. The sealing ring 8 is inserted into the middle of the sealing groove 7. During operation, when the permeation detection shell 1 and the sealing cover plate 2 are combined, the sealing ring 8 will be inserted into the middle of the sealing groove 7, so that the gap between the sealing cover plate 2 and the permeation detection shell 1 is effectively sealed, ensuring the sealing performance of the permeation detection shell 1 during use and reducing the risk of water vapor leaking out from the contact between the permeation detection shell 1 and the sealing cover plate 2.

[0028] Furthermore, such as Figure 5 As shown, the top of the fixed shell 42 is provided with a through groove 43, and a rectangular block 49 is fixed to the side wall at the bottom of the pull rod 41. During operation, when the activated carbon adsorption plate 4 is disassembled, the pull rod 41 will drive the rectangular block 49 to move together. The rectangular block 49 will pass through the through groove 43. At this time, the pull rod 41 is rotated so that the rectangular block 49 is stuck at the top of the fixed shell 42, so that the activated carbon adsorption plate 4 will not fall into the middle of the exhaust pipe 3 automatically, which makes it convenient to disassemble the activated carbon adsorption plate 4.

[0029] Furthermore, such as Figures 4-5As shown, the plug-in block 47 is trapezoidal in shape, and the outer wall of the plug-in block 47 is interference-fitted with the inner wall of the plug-in groove 44. During operation, by setting the plug-in block 47 to a trapezoidal shape and interfering with the middle of the plug-in groove 44, the stability of the activated carbon adsorption plate 4 is ensured, and the practicality is improved.

[0030] Furthermore, such as Figures 3-4 As shown, a spring 46 is fixedly connected to the bottom of the moving block 45. The bottom of the spring 46 is fixedly connected to the middle of the slide groove 10. During operation, the spring 46 ensures that the activated carbon adsorption plate 4 is located on the top side of the middle of the exhaust pipe 3 when not in use. After the activated carbon adsorption plate 4 has been used for a period of time, its mass will change due to the absorption of harmful substances in water vapor. At this time, the activated carbon adsorption plate 4 will descend and drive the moving block 45 to move. The moving block 45 will squeeze the spring 46. At this time, the user can observe the length of the pull rod 41 outside to observe the usage status of the activated carbon adsorption plate 4, which is convenient for timely replacement and improves practicality.

[0031] Furthermore, such as Figure 2 As shown, the end of the limiting plate 53 is set with an inclined surface. During operation, the inclined surface ensures that the push block 5 does not need to be pushed when installing the sealing cover plate 2, which improves the convenience of installation.

[0032] Working Principle: When performing dye penetration testing, the product can be placed in the middle of the penetration testing shell 1, and the dye penetration solution can be poured in. Then, the sealing cover 2 is placed on top of the penetration testing shell 1. The shell 1 can then be placed on a heating device for heating, improving the penetration effect. During heating, the dye penetration solution will boil, and the resulting water vapor will be discharged through the exhaust pipe 3. During this discharge, the water vapor needs to pass through the activated carbon adsorption plate 4. The activated carbon adsorption plate 4 adsorbs harmful substances in the water vapor, reducing the risk of the water vapor posing a hazard to the outside air. When the activated carbon adsorption plate 4 needs to be replaced after a period of use, it can be... Pulling the lever 41 will cause the moving block 45 to move via the fixed post 48, moving it to the middle of the fixed housing 42. At this time, the activated carbon adsorption plate 4 will move out from the middle of the exhaust pipe 3. Directly push the activated carbon adsorption plate 4 to disengage the insertion block 47 from the middle of the insertion groove 44. This allows the activated carbon adsorption plate 4 to be removed. During installation, simply insert the activated carbon adsorption plate 4 into the middle of the moving block 45. During insertion, ensure that the insertion block 47 can be smoothly inserted into the middle of the insertion groove 44 until the insertion block 47 is fully inserted into the middle of the insertion groove 44. Then, push the lever 41 in the opposite direction to move the activated carbon adsorption plate 4 to the middle of the exhaust pipe 3.

[0033] When merging the permeation detection housing 1 and the sealing cover 2, the sealing cover 2 can be directly placed on top of the permeation detection housing 1. During the fitting process, the limiting plate 53 will contact the permeation detection housing 1, and the permeation detection housing 1 will push the limiting plate 53 along the inclined surface of the limiting plate 53. The limiting plate 53 will rotate with the rotating rod 52, and drive the rotating rod 52 to move. The rotating rod 52 will change the angle of the connecting plate 51, and at the same time, the other end of the connecting plate 51 will rotate with the push block 5, and drive the push block 5 to slide in the middle of the slide groove 9 until the limiting plate 53 coincides with the rectangular groove 6. At this time, the limiting plate 53 can be reset and inserted in the middle of the rectangular groove 6 to limit the sealing cover 2. In this way, the permeation detection housing 1 and the sealing cover 2 will be stably merged together. When disassembling, simply push the push block 5. The subsequent structural movement is the same as above, until the limiting plate 53 is disengaged from the middle of the rectangular groove 6, and the sealing cover 2 can be removed. It is quick and convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
