Description
A stripping groove for integrated circuit components Technical Field
[0001] This invention belongs to the field of stripping tank technology, and specifically relates to a stripping tank for integrated circuit accessories. Background Technology
[0002] In the processing and manufacturing of integrated circuit components, removing the film is a core process step. Essentially, it involves removing various functional film layers that are attached or coated on the surface of the component during processing. The core purpose is to clear surface obstacles for subsequent processes, ensure the processing accuracy and yield of the component, and at the same time avoid irreversible impacts on the performance and reliability of integrated circuits caused by film residue.
[0003] In the stripping process of small and medium batch integrated circuit components, the components need to be placed in a carrier basket, and then the workers hold the carrier basket and slowly place it into the stripping tank for subsequent stripping. However, during placement, the components or carrier basket need to be completely immersed in the stripping solution in the stripping tank. Therefore, during placement, the workers' hands are at risk of coming into contact with the internal stripping solution. Even if the workers wear protective gear, the protective gear is at risk of being corroded and damaged by the stripping solution. Summary of the Invention
[0004] The purpose of this invention is to provide an integrated circuit accessory stripping tank, so that when the carrier basket is placed into the stripping tank, the operator does not need to come into close contact with the stripping liquid in the stripping tank, thus making it safer.
[0005] To achieve the above objectives, embodiments of the present invention provide an integrated circuit accessory stripping tank, including a tank body and a carrier basket, and further including a driving translation component, a lifting component, a pull rod and a sealing component. When the bottom end of the carrier basket contacts the inner bottom end of the tank body, the pull rod is located above the cover plate. When placing the carrier basket, it can be ensured that the stripping liquid in the tank body completely soaks the carrier basket and the pull rod does not extend into the interior of the tank body.
[0006] The driving translation component is disposed on the tank body and is used to drive the carrier basket to move to the side of the tank body. The lifting component is disposed on the driving translation component and is used to adjust the height of the carrier basket. The pull rod is disposed on the lifting component and the sealing component is disposed on the tank body and is used to isolate the pull rod from the demolding liquid inside the tank body.
[0007] To enable the vehicle basket to be moved to the side of the tank when the accessories are placed inside, the driving translation component further includes a support cover, a reciprocating screw, a motor, and a moving component. Two support covers are provided, each fixedly installed on one side of the tank. The reciprocating screw is rotatably installed inside one of the support covers, and a matching slider is mounted on the reciprocating screw. The motor is installed on the side of the support cover, and its output end is coaxially and fixedly connected to the reciprocating screw. The moving component is located inside the other support cover and includes a sliding rod and a moving block. The sliding rod is fixedly installed inside the other support cover, and the moving block is slidably installed on the sliding rod.
[0008] To place the vehicle basket into the slot after the accessories are placed inside, the lifting assembly further includes a sliding plate, a lifting rod, and a fixing assembly. The top of both the slider and the moving block is fixedly mounted with the sliding plate. The lifting rod is slidably mounted on the side of each sliding plate. A pull rod is fixedly mounted on the top of two lifting rods, and the vehicle basket is fixedly mounted between the two lifting rods. The fixing assembly is provided on the side of each sliding plate. The fixing assembly includes a rotating shaft, a fixing rod, and a baffle. The rotating shaft is rotatably mounted on the side of the sliding plate, and the fixing rod is fixedly mounted on the side of the rotating shaft. A through slot is formed on the side of the fixing rod, and the baffle is rotatably mounted on the side of the fixing rod via the rotating shaft. The height of the through slot of the fixing rod is greater than the thickness of the lifting rod, so that when the fixing rod rotates to the side of the lifting rod, the side of the lifting rod can pass through the through slot.
[0009] To prevent the accessories and the carrier basket from being splashed with demolding liquid when placed simultaneously into the tank, the sealing assembly further includes a cover plate, a limiting block, and a limiting frame. Two cover plates are provided, both slidably mounted on the top of the tank. The limiting block is fixedly mounted on both sides of one cover plate, and the limiting frame is fixedly mounted on both sides of the other cover plate. The limiting block has a slot on its side that matches the side of the limiting frame. When the sides of the two cover plates are in contact, the side of the limiting frame inserts into the slot of the limiting block. After the two cover plates are in contact, they are fixed in place by the engagement of the limiting frame and the limiting block. Two U-shaped grooves are provided on the side of the cover plate, which match the side of the lifting rod. Even when the two cover plates are in contact to seal, the lifting rod can still move up and down.
[0010] The significant technical advantages of this invention are as follows: When removing integrated circuit components, the carrier basket is first removed using a lifting assembly. The components are then placed back into the carrier basket and reinstalled onto the lifting assembly. The operator holds a lever to slowly lower the carrier basket. Once the bottom of the carrier basket enters the tank, a sealing cover assembly seals the opening of the tank. During subsequent lowering, the cover separates the inside of the tank from the outside, preventing the operator's hands from contacting the stripping liquid inside the tank during descent. Furthermore, after stripping the circuit components, the carrier basket is lifted out of the tank and then driven by a translation assembly to install on the lifting assembly. The carrier basket on the assembly moves to the side of the tank. Since the carrier basket is covered with dripping stripping liquid after detaching from the tank, the translation component moves it without requiring manual removal by the operator. This significantly reduces the chance of the operator coming into contact with the stripping liquid and also prevents the operator from moving away from the top of the tank when handling the carrier basket, thus avoiding contact between the stripping liquid vapor and the skin. In summary, this stripping tank, through the coordinated operation of the translation component, lifting component, pull rod, and sealing component, minimizes the operator's contact with the stripping liquid inside the tank when placing and removing the carrier basket, thus ensuring greater safety.

[0021] Please refer to Figures 1 to 7, which show an integrated circuit accessory stripping tank according to an embodiment of the present invention, including a tank body 1 and a carrier basket 2. When it is necessary to strip the integrated circuit accessory, the accessory is first placed in the carrier basket 2, and then immersed in the tank body 1, and then the surface of the accessory is stripped.
[0022] During demolding, the accessories are first placed in the carrier basket 2, and then the carrier basket 2 is placed above the tank 1 by the lifting assembly, as shown in Figures 3, 4 and 7. The lifting assembly includes a sliding plate 10, a lifting rod 11 and a fixing assembly. The top of the slider 6 and the moving block 9 are both fixedly installed with the sliding plate 10. The side of each sliding plate 10 is slidably installed with the lifting rod 11. The pull rod 3 is fixedly installed at the top of the two lifting rods 11, and the carrier basket 2 is fixedly installed between the two lifting rods 11. The side of each sliding plate 10 is provided with a fixing assembly, which includes a rotating shaft 12, a fixing rod 13 and a baffle 14. The rotating shaft 12 is rotatably installed on the side of the sliding plate 10, the fixing rod 13 is fixedly installed on the side of the rotating shaft 12, and the side of the fixing rod 13 has a through slot. The baffle 14 is rotatably installed on the side of the fixing rod 13 by a rotating shaft.
[0023] Specifically, the worker holds the lever 3 and aligns the two lifting rods 11 with the grooves of the two sliding plates 10 respectively. It should be noted that the two sliding plates 10 are placed opposite each other, and each of the two sliding plates 10 has a vertical groove on its side, and the top of the vertical groove is open. That is, the lifting rod 11 can be aligned with the top opening of the vertical groove and then slid into the vertical groove. After installation, it drives the carrier basket 2 to move down slowly. When the bottom of the carrier basket 2 touches the demolding liquid in the tank 1, it stops moving down.
[0024] Subsequently, as shown in Figures 5 and 6, the opening of the tank 1 is sealed using a sealing assembly. The sealing assembly includes a cover plate 15, a limiting block 16, and a limiting frame 17. Two cover plates 15 are provided, both of which are slidably installed on the top of the tank 1. One cover plate 15 has a limiting block 16 fixedly installed on both sides, and the other cover plate 15 has a limiting frame 17 fixedly installed on both sides. The side of the limiting block 16 has a slot that matches the side of the limiting frame 17. Specifically, another worker slides the two cover plates 15 relative to each other on the top of the tank 1. When the sides of the two cover plates 15 are in contact, the side of the limiting frame 17 inserts into the slot of the limiting block 16. Thus, through the engagement of the limiting frame 17 and the limiting block 16, the two cover plates 15 are fixed. The side of the cover plate 15 has a slot that matches the side of the limiting frame 17. There are two U-shaped grooves, and the U-shaped grooves of the two cover plates 15 are arranged opposite each other. The U-shaped grooves are adapted to the side of the lifting rod 11. When the lifting rod 11 moves up and down, it can pass through the U-shaped groove of the cover plate 15. Therefore, when the lifting rod 11 moves up and down, it will not block the cover plate 15 from fitting. After the cover plate 15 is fitted, it will not block the lifting rod 11 from moving up and down. At this time, the worker holds the pull rod 3 and lowers the carrier basket 2. Because the bottom end of the carrier basket 2 contacts the inner bottom end of the tank body 1, the pull rod 3 is located above the cover plate 15. Therefore, when the carrier basket 2 and the accessories are completely immersed in the demolding liquid in the tank body 1, the pull rod 3 is still located above the cover plate 15. At this time, the cover plate 15 separates the inside and outside of the tank body 1. No matter how the worker moves, he will not be splashed by the demolding liquid, which is safer. In addition, during demolding, the top of the tank body 1 is equipped with a retractable anti-fog cover, which, together with the cover plate 15, reduces steam leakage. The motor 7 is made of waterproof and corrosion-resistant material.
[0025] After demolding, the two cover plates 15 are moved in opposite directions. Then, the worker holds the pull rod 3 again and lifts it upwards until the carrier basket 2 is directly above the tank 1. Then, the fixed rod 13 is rotated through the rotating shaft 12. Because the height of the through slot of the fixed rod 13 is greater than the thickness of the lifting rod 11, the lifting rod 11 can pass through the through slot of the fixed rod 13, thereby supporting the lifting rod 11. The side of the fixed rod 13 has a baffle 14 that rotates through the damping shaft. When the fixed rod 13 is rotated, the baffle 14 can be rotated upwards. When the lifting rod 11 is in the through slot of the fixed rod 13, the baffle 14 is rotated downwards to seal the opening of the through slot and prevent the lifting rod 11 from falling out of the opening of the through slot during subsequent movement.
[0026] After being lifted up, the container basket 2 is left to stand for a period of time to drain some of the stripping liquid. As shown in Figure 2, the carrier basket 2 is moved to the side of the tank 1 by driving the translation component. The translation component includes a support cover 4, a reciprocating screw 5, a motor 7, and a moving component. There are two support covers 4, which are fixedly installed on both sides of the tank 1. The reciprocating screw 5 is rotatably installed in one of the support covers 4, and a matching slider 6 is installed on the reciprocating screw. The motor 7 is installed on the side of the support cover 4, and the output end of the motor 7 is coaxially and fixedly connected to the reciprocating screw 5. The moving component is set in the other support cover 4. The moving component includes a sliding rod 8 and a moving block 9. The sliding rod 8 is fixedly installed in the other support cover 4, and the moving block 9 is slidably installed on the sliding rod 8.
[0027] Specifically, the motor 7 is started, and the output end of the motor 7 drives the reciprocating screw 5 to rotate inside the support cover 4. The slider 6 moves on the reciprocating screw 5, which in turn drives one of the sliding plates 10 and the lifting rod 11 to move. With the carrier basket 2 connected, the other sliding plate 10 and the lifting rod 11 move synchronously, and the moving block 9 moves horizontally on the sliding rod 8 at the same time, thus moving the carrier basket 2 to the side of the tank 1, away from the top of the tank 1. Finally, the worker holds the pull rod 3 again and rotates the fixed rod 13 to the side, pulling the lifting rod 11 away from the sliding plate 1. 0, and remove the vehicle basket 2. It should be added that the shape design of the slider 6 matches the helical groove of the reciprocating screw 5. When the reciprocating screw 5 rotates, the side wall of the helical groove will generate an axial thrust on the slider 6 embedded therein. The slider 6 can move along the axial trajectory of the reciprocating screw 5, thereby moving up and down. When the slider 6 reaches the end of the reciprocating screw 5, the slider 6 will smoothly transition to the reverse helical groove, thereby realizing reciprocating movement. This is a well-known technology and will not be elaborated further. In addition, the reciprocating screw 5 is equipped with a corrosion-resistant telescopic protective cover to protect the reciprocating screw 5.
[0028] Working principle: When removing the film from integrated circuit components, the stripping solution is first precisely prepared according to the process formula to ensure that the concentration and ratio meet the stripping requirements of the components. Then, the stripping solution is slowly added to tank 1 to the process calibration level. Subsequently, the heating device is started to heat the stripping solution to the process set temperature and let it stand at a constant temperature for 5-10 minutes to ensure uniform liquid temperature. The top of tank 1 is equipped with a liquid level scale line, and the bottom of tank 1 is equipped with a heating tube and a temperature sensor. The temperature controller controls the stripping solution to the specified temperature.
[0029] Then, the accessories are placed in the carrier basket 2. The worker holds the lever 3 and aligns the two lifting rods 11 with the grooves of the two sliding plates 10 respectively. The lifting rods 11 are then slid into the vertical grooves. After installation, the carrier basket 2 is slowly lowered. The lowering stops when the bottom of the carrier basket 2 touches the stripping liquid in the tank 1. Another worker slides the two cover plates 15 relative to each other at the top of the tank 1. After the sides of the two cover plates 15 are in contact, the side of the limiting bracket 17 is inserted into the slot of the limiting block 16. The two cover plates 15 are fixed by the engagement of the limiting bracket 17 and the limiting block 16. At this time, the worker holds the lever 3 and lowers the carrier basket 2, immersing the carrier basket 2 and the accessories completely in the stripping liquid in the tank 1. The lever 3 is still above the cover plate 15. The cover plate 15 separates the inside and outside of the tank 1, preventing the worker from being splashed with the stripping liquid, thus ensuring safety.
[0030] At this time, the stirring function in tank 1 can be activated, the corresponding device can be started, the contact effect between the stripping liquid and the film layer can be enhanced, the process and timing can be started, and real-time observation or monitoring can be carried out during the stripping process. Observe that the stripping liquid is free from turbidity, stratification, etc., and that the accessories are free from floating, displacement, etc. It should be added that the tank 1 is equipped with a stirring paddle, which is driven to rotate by the driving component, thereby enhancing the uniformity of contact between the stripping liquid and the surface of the accessories.
[0031] After demolding is complete, turn off the heating and stirring functions, move the two cover plates 15 in opposite directions, and then the worker holds the pull rod 3 again to lift it upwards until the carrier basket 2 is directly above the tank 1. Then, rotate the fixed rod 13 through the rotating shaft 12, so that the fixed rod 13 supports the lifting rod 11. The side of the fixed rod 13 has a baffle 14 that rotates through the damping shaft. When the fixed rod 13 is rotated, the baffle 14 can be rotated upwards. When the lifting rod 11 is in the through groove of the fixed rod 13, the baffle 14 is rotated downwards to seal the opening of the through groove, preventing the lifting rod 11 from falling out of the through groove opening during subsequent movement. After the rapid upward movement is completed, the worker moves away from directly above the tank 1 to avoid the vapor of the demolding solution from causing skin damage. After the demolding solution has drained, start the electric motor. The output of the motor 7 drives the reciprocating screw 5 to rotate inside the support cover 4. The slider 6 moves on the reciprocating screw 5, thereby moving one of the sliding plates 10 and the lifting rod 11. With the connection of the carrier basket 2, the other sliding plate 10 and the lifting rod 11 move synchronously, and the moving block 9 moves horizontally on the sliding rod 8, thereby moving the carrier basket 2 to the side of the tank 1, away from the top of the tank 1. Finally, the worker holds the pull rod 3 again and rotates the fixing rod 13 to the side, pulls the lifting rod 11 away from the sliding plate 10, and takes down the carrier basket 2. This avoids the worker staying above the tank 1 for a long time when moving the carrier basket 2. If the parts are heavy, they can also be moved to the side of the tank 1 by moving the carrier basket 2, and then taken out.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
