Technical Field

[0002] MOS chip, whose full English name is MOSFET, namely metal-oxide semiconductor field effect transistor, is a semiconductor device that uses the electric field effect of the control input loop to control the output loop current. Packaging is the last step in MOS chip manufacturing and is also a key step in converting the chip into a usable device. The main function of the packaging equipment is to provide a protective shell for the MOS chip. This shell can support the chip, prevent it from physical damage, and also play a role in cooling and electrical connection.
[0003] In the prior art, the patent document "CN118558542B" discloses "a chip packaging device"; it includes a base and a table top, the table top slides up and down on the upper side of the base, a limit mechanism is provided between the table top and the base to limit the separation of the table top and the base, and a vibration motor is fixedly connected to the lower end surface of the table top; in this scheme, the base and the chip surface are baked before the chip and the substrate are injected with glue for packaging, so as to facilitate drying of water stains on the surface of the substrate and the chip, which is beneficial to avoid encapsulating water stains in the colloid, which is beneficial to avoid retaining bubbles in the colloid, and while drying the water stains, it is also convenient to preheat the substrate and the chip, so as to facilitate improving the fluidity of the filling glue during the injection process, and thus facilitate filling the filling glue into the gap under the pin, and after drying the water stains, the dust and impurities after the drying of the water stains are cleaned by large-scale vibration and blowing, which is further beneficial to avoid encapsulating bubbles in the colloid.
[0004] The above-mentioned "a chip packaging device" still has some disadvantages. For example, during the packaging process of the existing MOS chip, the shell filled with the packaging material needs to be heated and cured to solidify the packaging material. During this process, the adhesion between the chip and the packaging material will be weakened due to the large temperature difference. If there is moisture and volatiles in the packaging material, direct curing will cause bubbles and gaps in the curing process, resulting in defects in the packaging process, affecting the final molding effect and quality of the MOS chip.

[0015] A method for using a packaging device for MOS chip processing comprises the following steps:
[0016] S1. By starting four electric push rods, the four electric push rods will synchronously push the side connection frame to move vertically when started. Through the fixation of the four side connection frames and the square protection box, the square protection box will be synchronously driven to move vertically when the side connection frame moves vertically. After the square protection box is lifted vertically, the packaging table on the top of the bottom support table is opened, and the top fixing plate will be synchronously driven to move synchronously during the vertical movement of the square protection box. Through the connection of the side fixing frames, the top fixing plate will be synchronously driven to move during the vertical movement of the top fixing plate. When the square protection box is lowered, the protection ring frame is synchronously driven to be lowered to the surface of the packaging table, and the outer filter on the surface of the protection ring frame is used to protect the solidified MOS chip placed on the surface of the packaging table;
[0017] S2. After the MOS chip is placed on the surface of the packaging table and the square protective box is lowered, the servo motor is started, and the inner transmission rod is driven to rotate by the servo motor. The transmission fan is driven to rotate along the inner side of the inner connecting tube by the rotating inner transmission rod. The transmission fan generates wind force to blow the external air out along one side of the inner connecting tube. In the process of the transmission fan rotating to blow the gas to the surface of the packaging table, the side storage box is started. The control panel on one side of the side storage box includes a wireless transmission module and a temperature control module. The temperature of the heater body is controlled by the temperature control module. At the same time, the connection of the inner transmission cable is used to drive the heater body to work when the side storage box is driven. After the heater body is started, it will heat up along the inner side of the inner connecting tube. After the temperature in the inner connecting tube rises to the specified temperature, the hot air is blown along the inner side of the inner connecting tube to the surface of the packaging table by the rotating transmission fan;
[0018] S3. When the transmission fan rotates and draws the external air in along the inner connection cylinder, through the connection of the top filter cylinder, the external air will first be drawn in along the top filter cylinder and sent out along the inner connection cylinder, and the top transmission ring connected to the inner side of the top filter cylinder through the top filter screen on the inner side of the top transmission ring will filter the drawn air;
[0019] S4. When the servo motor drives the inner transmission rod to rotate, the rotating inner transmission rod will synchronously drive the top transmission plate to rotate, and the rotating top transmission plate will synchronously drive multiple top cleaning brushes to rotate, by uniformly rotating the top cleaning brush along the surface of the top filter, while the inner transmission rod drives the transmission fan to rotate to generate wind force, the top cleaning brush is driven to clean the surface of the top filter, thereby cleaning the surface of the top filter;
[0020] S5. The transmission motor is stably fixed to the bottom of the top fixed plate by using two top fixing rods. The transmission motor is started to work and drive the bottom transmission frame to rotate. The rotating bottom transmission frame drives the bottom connecting frame to rotate. The bottom connecting frame drives the top sliding block to move during the rotation process, driving the top sliding block to slide along the surface of the inner annular slide rail. The top sliding block is in a "T" shape. At the same time, the inner side of the inner annular slide rail is in a ring-shaped "T". The bottom connecting frame is driven by the bottom transmission frame to rotate along the inner side of the protective ring frame to adjust the position where the transmission fan blows out hot air.
[0021] S6. While the transmission motor is driving the bottom transmission frame to rotate, through the connection of bolts, the rotating bottom transmission frame will synchronously drive the L fixing frame to rotate, the rotating L fixing frame will synchronously drive the side transmission plate to move, the continuously rotating side transmission plate will synchronously drive the side cleaning brush to rotate, the rotating side cleaning brush moves along the surface of the outer filter, and the outer filter is cleaned synchronously during the process of adjusting the position of the bottom connecting frame after the transmission motor is started.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] 1) After the square protective box is lifted vertically, the packaging table on the top of the bottom support table is opened, so that the operator can place and take out the MOS chip. In the process of vertical movement of the square protective box, the top fixing plate will be driven to move synchronously. Through the connection of the side fixing frame, the protective ring frame will be driven to move synchronously in the process of vertical movement of the top fixing plate. At the same time, the side observation window opened on the surface of the square protective box allows the operator to observe the MOS chip during preheating;
[0024] 2) The transmission fan is driven by the rotating inner transmission rod to rotate along the inner side of the inner connecting tube. The transmission fan generates wind to blow the external air out along one side of the inner connecting tube. The temperature of the heater body is controlled by the temperature control module. At the same time, the connection of the inner transmission cable is used to drive the heater body to work when the side storage box is driven. After the heater body is started, it will heat up along the inner side of the inner connecting tube. After the temperature in the inner connecting tube rises to the specified temperature, the hot air is blown along the inner side of the inner connecting tube to the surface of the packaging table by the rotating transmission fan, which is convenient for preheating the MOS chip on the surface of the packaging table and improving the adhesion between the MOS chip and the packaging material. During the cooling after curing, after the heater body is turned off, the wind temperature generated by the rotating transmission fan is relatively low, and the continuous rotation of the bottom connecting frame improves the cooling efficiency of the MOS chip on the surface of the packaging table after packaging and curing.
[0025] 3) Through the connection of the top filter cylinder, the external air will first be drawn in along the top filter cylinder and sent out along the inner connection cylinder, and the top transmission ring connected to the inner side of the top filter cylinder will filter the drawn air using the top filter net inside the top transmission ring. The top filter net blocks dust, hair and other tiny impurities in the air, preventing pollutants from adhering to the MOS chip or the circuit board around its package, thereby improving the stability of the MOS chip during the packaging process, reducing the situation of circuit breaking or poor heat dissipation, and increasing the service life of the MOS chip;
[0026] 4) The rotating top transmission plate will synchronously drive multiple top cleaning brushes to rotate. By evenly rotating the top cleaning brush along the surface of the top filter, the inner transmission rod drives the transmission fan to rotate to generate wind force while driving the top cleaning brush to clean the surface of the top filter, and clean the dust and hair particles accumulated on the surface of the top filter during the filtering process, reducing the blockage of the top filter surface caused by dust and hair accumulation, improving the gas passing rate of the top filter, eliminating the need for operators to clean repeatedly, reducing the workload of operators, and at the same time, the operator holds the top holding rod and rotates the top transmission ring, and the top transmission ring is connected to the threaded connection with the top filter cartridge through the external thread surface of the top transmission ring, and the top transmission ring is rotated along the inner thread of the top filter cartridge until it is separated, thereby improving the portability of the top transmission ring and the top filter cartridge for disassembly;
[0027] 5) By starting the transmission motor and driving the bottom transmission frame to rotate, the rotating bottom transmission frame will drive the bottom connecting frame to rotate, and the bottom transmission frame drives the bottom connecting frame to rotate along the inner side of the protective ring frame, so as to facilitate the adjustment of the position where the transmission fan blows out hot air, and preheat evenly according to different positions, thereby improving the preheating effect;
[0028] 6) When the square protective box is lowered, the protective ring frame is simultaneously driven to lower to the surface of the packaging table, and the outer filter on the surface of the protective ring frame is used to protect the solidified MOS chip placed on the surface of the packaging table, thereby reducing the contact between dust particles in the external environment and the MOS chip during the preheating process. A rotating side cleaning brush is used to move along the surface of the outer filter. When the position of the bottom connecting frame is adjusted after the transmission motor is started, the outer filter is cleaned synchronously, and dust accumulation generated during filtering on the surface of the outer filter is cleaned, thereby improving the filtering effect of the outer filter, reducing the contact between dust particles and the MOS chip on the surface of the packaging table, and improving the protection of the MOS chip during the preheating process.

[0062] S1. First, start the four electric push rods 304. When started, the four electric push rods 304 will synchronously push the side connecting frame 305 to move vertically. The four side connecting frames 305 are fixed to the square protective box 301. When the side connecting frame 305 moves vertically, it will synchronously drive the square protective box 301 to move vertically. After the square protective box 301 is vertically lifted, the packaging table 2 on the top of the bottom support table 1 is opened, so that the operator can place and take out the MOS chip. In addition, during the vertical movement of the square protective box 301, the top fixing plate 306 will be synchronously driven to move synchronously. The connection of the side fixing frame 307 will synchronously drive the protection ring frame 308 to move during the vertical movement of the top fixing plate 306, and synchronously drive the protection ring frame 308 to be lowered to the surface of the packaging table 2 when the square protection box 301 is lowered, and the outer filter 309 on the surface of the protection ring frame 308 is used to protect the MOS chip placed on the surface of the packaging table 2 to reduce the contact between dust particles in the external environment and the MOS chip during the preheating process. At the same time, the side observation window 302 opened on the surface of the square protection box 301 allows the operator to observe the MOS chip during the preheating process;
[0063] S2. After the MOS chip is placed on the surface of the packaging table 2 and the square protective box 301 is lowered, the servo motor 409 is started, and the inner transmission rod 4010 is driven to rotate by the servo motor 409. The rotating inner transmission rod 4010 drives the transmission fan 4011 to rotate along the inner side of the inner connecting tube 4013. The transmission fan 4011 will generate wind force to blow the external air out along one side of the inner connecting tube 4013, and the transmission fan 4011 will be protected by the protective rod 4014 on the side of the inner connecting tube 4013 when rotating, thereby improving the stability of the transmission fan 4011 when rotating. In the process of the transmission fan 4011 rotating to blow the gas to the surface of the packaging table 2, the side storage box 601 is started to work. The control panel 602 on one side of the side storage box 601 includes a wireless transmission module and a temperature control module. The wireless transmission module allows the operator to The temperature control module is operated remotely, and the temperature of the heater body 605 is controlled by the temperature control module. At the same time, the connection of the internal transmission cable 604 is used to drive the heater body 605 to work when the side storage box 601 is driven. After the heater body 605 is started, it will heat up along the inner side of the inner connecting tube 4013. After the temperature in the inner connecting tube 4013 rises to the specified temperature, the hot air is blown along the inner side of the inner connecting tube 4013 to the surface of the packaging table 2 through the rotating transmission fan 4011, so as to preheat the MOS chip on the surface of the packaging table 2 and improve the adhesion between the MOS chip and the packaging material. When cooling after solidification, after the heater body 605 is turned off, the wind temperature generated by the rotating transmission fan 4011 is relatively low, and the continuous rotation of the bottom connecting frame 404 improves the cooling efficiency of the MOS chip on the surface of the packaging table 2 after solidification.
[0064] S3, when the transmission fan 4011 rotates and draws external air in along the inner connection tube 4013, through the connection of the top filter tube 501, the external air will first be drawn in along the top filter tube 501 and sent out along the inner connection tube 4013, and the top transmission ring 502 connected to the inner side of the top filter tube 501 by the thread, uses the top filter net 504 inside the top transmission ring 502 to filter the drawn air, and the top filter net 504 blocks dust, hair and other tiny impurities in the air, preventing pollutants from adhering to the MOS chip or the circuit board around its package, thereby improving the stability of the MOS chip during the packaging process, reducing the situation of circuit breaking or poor heat dissipation, and increasing the service life of the MOS chip;
[0065] S4. At the same time, when the servo motor 409 drives the inner transmission rod 4010 to rotate, the rotating inner transmission rod 4010 will synchronously drive the top transmission plate 507 to rotate, and the rotating top transmission plate 507 will synchronously drive multiple top cleaning brushes 508 to rotate, and the top cleaning brushes 508 will rotate evenly along the surface of the top filter 504. While the inner transmission rod 4010 drives the transmission fan 4011 to rotate to generate wind force, it drives the top cleaning brushes 508 to clean the surface of the top filter 504, and the dust accumulated on the surface of the top filter 504 during the filtering process is removed. The top filter 504 is cleaned by dust and hair particles, and the clogging of the surface of the top filter 504 caused by dust and hair accumulation is reduced, and the gas passing rate of the top filter 504 is improved. The operator does not need to clean it repeatedly, which reduces the workload of the operator. At the same time, the operator holds the top holding rod 506 and rotates the top transmission ring 502. The outer thread surface 503 on the surface of the top transmission ring 502 is connected with the thread of the top filter cartridge 501, and the top transmission ring 502 is rotated along the inner thread of the top filter cartridge 501 until it is separated, which improves the portability of the top transmission ring 502 and the top filter cartridge 501 for disassembly;
[0066] S5. At the same time, the two top fixing rods 401 are used to fix the transmission motor 402 stably on the bottom of the top fixing plate 306. By starting the transmission motor 402 to work and drive the bottom transmission frame 403 to rotate, the rotating bottom transmission frame 403 will drive the bottom connecting frame 404 to rotate, and the bottom connecting frame 404 will drive the top sliding block 405 to move during the rotation, driving the top sliding block 405 to slide along the surface of the inner annular slide rail 407, and the top sliding block 405 is in a "T" shape, and the inner side of the inner annular slide rail 407 is in a ring-shaped "T" shape. Through the sliding of the inner annular slide rail 407 and the top sliding block 405, the stability of the bottom transmission frame 403 driving the bottom connecting frame 404 to rotate is improved, and the bottom connecting frame 404 is driven by the bottom transmission frame 403 to rotate along the inner side of the protective ring frame 308, so as to facilitate the adjustment of the position where the transmission fan 4011 blows out hot air, and uniform preheating is performed according to different positions, thereby improving the preheating effect;
[0067] S6. While the transmission motor 402 is driving the bottom transmission frame 403 to rotate, through the connection of the bolts 702, the rotating bottom transmission frame 403 will synchronously drive the L fixing frame 701 to rotate, and the rotating L fixing frame 701 will synchronously drive the side transmission plate 703 to move, and the continuously rotating side transmission plate 703 will synchronously drive the side cleaning brush 704 to rotate, and the rotating side cleaning brush 704 will move along the surface of the outer filter 309. After the transmission motor 402 is started, the outer filter 309 is cleaned synchronously in the process of adjusting the position of the bottom connecting frame 404, and the dust accumulation generated when filtering on the surface of the outer filter 309 is cleaned, thereby improving the filtering effect of the outer filter 309, reducing the contact between dust particles and the MOS chip on the surface of the packaging table 2, and improving the protection of the MOS chip during the preheating process;
