Description

Technical Field

[0001] The present invention belongs to the technical field of chip packaging, and in particular relates to a packaging control system for multi-chip production. Background Art

[0002] A chiplet, also known as a core particle or chiplet, is a type of die (bare die) that meets specific functions. Using die-to-die interconnect technology, multiple module chips are packaged together with the underlying base chip to form a system-on-chip, enabling a new form of IP reuse. Current mainstream system-on-chip (SoC) designs utilize photolithography to fabricate multiple computing units responsible for different types of tasks onto a single wafer. Chiplet+chiplet takes a complex SoC chip and decomposes it into distinct computing or functional units from the outset. Each unit is then manufactured separately using the most suitable semiconductor process. Advanced packaging technologies are then used to interconnect these units, ultimately integrating and packaging them into a system-on-chip set.

[0003] In the multi-chip manufacturing process, after completing the manufacturing of a single chip, it is often necessary to perform plastic sealing on its surroundings. The plastic sealing process is to use a polyester film coated with hot melt adhesive to bond the sealed items inside the plastic film through a laminating machine. Since the processing is carried out under a certain pressure and high temperature, and uses high-quality polyester film and hot melt adhesive with good transparency, the chip needs to be encapsulated and protected with plastic sealing resin after bonding at a certain pressure and temperature during production. The entire process requires the use of plastic sealing equipment.

[0004] However, existing chip encapsulation processes mostly involve directly securing the chip to a molding table. After encapsulating one side of the chip, the chip must be removed from the molding table, flipped over, and reattached to the molding table before encapsulating the other side. This encapsulation process requires frequent chip removal and repositioning, significantly impacting chip encapsulation efficiency. To address this issue, we have developed a packaging control system for multi-chip production to address these challenges. Summary of the Invention

In the initial state, the first conversion groove 205 is aligned with the first guide groove 108 and the two are connected, and the second conversion groove 206 is aligned with the second guide groove 109 and the two are connected. The entire chip conveying mechanism 3 is in the initial position (as shown in FIG. Figure 1 shown).

[0039] In some embodiments, as Figure 1 、 Figure 11 and Figure 12As shown, the lifting control assembly 4 includes a U-shaped mounting frame 401 sleeved on the plastic-sealed carrier frame 104, a limiting groove 402 is provided on the U-shaped mounting frame 401 to slide with the horizontal guide rail 105, a support frame 403 is fixedly provided on the top of the U-shaped mounting frame 401, a lifting cylinder 404 is installed on the support frame 403, and an internal thread plate 405 sleeved on the power screw 106 is fixed on the bottom of the U-shaped mounting frame 401, and the internal thread plate 405 is threadedly connected to the power screw 106 through the limiting groove 402.

In the initial state, the top of the U-shaped lifting plate 408 is against the top inside the U-shaped mounting frame 401.

[0040] In some embodiments, as Figure 1 、 Figure 13 and Figure 14 As shown, the flip control assembly 5 also includes a lifting frame 505 slidably arranged on the limiting guide seat 407 (the cooperation between the lifting frame 505 and the limiting guide seat 407 ensures the smooth up and down movement of the entire flip control assembly 5), and a first rotating shaft 506 and a second rotating shaft 507 are rotatably arranged on the lifting frame 505. One end of the first rotating shaft 506 passes through the limiting channel 406 and the U-shaped lifting plate 408 and is fixedly connected to the support plate 501 (when the U-shaped lifting plate 408 is controlled to move up and down, the first rotating shaft 506 can be driven to slide along the limiting channel 406, and in the initial state, the first rotating shaft 506 is against the top of the limiting channel 406). A first transmission wheel 508 is fixedly installed at the other end, a positioning plate 509 rotatably connected to the U-shaped lifting plate 408 is fixed to the side surface of the first rotating shaft 506, and a second transmission wheel 510 is fixedly installed on the side surface of the second rotating shaft 507. The first transmission wheel 508 and the second transmission wheel 510 are connected by a transmission belt 511, and the support plate 502 is fixedly set at the end of the second rotating shaft 507 (so that synchronous rotation between the support plate 501 and the support plate 502 can be achieved), and a negative pressure generator 512 for controlling the negative pressure in the inner cavity of the hollow negative pressure part 503 is installed on the support plate 502 (the negative pressure generator 512 is a conventional device in the prior art, so its structure is not described in detail).

[0041] When a chip 6 (the chip 6 is a single-core structure in a multi-core structure, which includes a conventional chip and a metal circuit layer) is pressed against the surface of the hollow negative pressure part 503, the negative pressure environment of the inner cavity of the hollow negative pressure part 503 is controlled by the negative pressure generator 512, so that the chip 6 is tightly adsorbed and fixed on the hollow negative pressure part 503, so that the position of the chip 6 on the hollow negative pressure part 503 is fixed. At this time, there is a certain distance between the top surface (first side) of the chip 6 and the plastic packaging component 102. Then, the U-shaped lifting plate 408 is controlled by the lifting cylinder 404 to move upward until it rests against the top of the U-shaped mounting frame 401. At this time, the first rotating shaft 506 just rests against the top of the limiting channel 406, and the first rotating shaft 506 is just aligned with the intersection of the first guide groove 108 and the rising groove 113. The top surface (first side) of the chip 6 is close to the bottom of the plastic packaging component 102. During the process, a guide wheel part 504 is slidably fitted inside the rising groove 113 (that is, the lower guide wheel part 504 is fitted in the rising groove 113, and the electromagnet at this position is in an energized and magnetic state, so that the lower guide wheel part 504 is inserted into the rising groove 113 under the action of the magnetic repulsion force). In the process of controlling the entire flip control component 5 to move upward by the lifting cylinder 404, the lower guide wheel part 504 gradually slides upward along the rising groove 113 from the intersection of the fourth guide groove 111 and the rising groove 113, and then the plastic sealing treatment of the top surface (first side) of the chip 6 is realized by the plastic sealing component 1 102 (of course, the plastic sealing component 1 102 and the plastic sealing component 2 103 can also be designed as a structure that can fine-tune the height up and down, for example, the height of the plastic sealing component 102 and the plastic sealing component 2 103 can be fine-tuned by the cylinder, and the specific setting is based on actual production needs) (step one).

[0042] Next, the electromagnet at the position of the first guide groove 108 is controlled to be energized and magnetized, and the corresponding guide wheel component 504 is inserted into the first guide groove 108 under the action of the magnetic repulsive force, and then the electromagnet at the lower position is controlled to be de-energized and demagnetized so that the lower guide wheel component 504 is separated from the rising groove 113 (that is, at this time only one guide wheel component 504 is fitted in the first guide groove 108, and the guide wheel components 504 in other directions are in their original state). Then, the power motor 107 controls the power screw 106 to rotate and drive the entire chip conveying mechanism 3 to move with the chip 6 toward the direction of the plastic packaging component 2 103. When the guide wheel component 504 in the first guide groove 108 enters the first conversion groove 205 and slides into the second conversion groove 206 along the arc conversion groove 207, the support plate 501 rotates clockwise under the action of the arc conversion groove 207. After rotating 90°, under the joint action of the first transmission wheel 508, the second transmission wheel 510 and the transmission belt 511, the hollow negative pressure part 503 on the support plate 502 rotates 90° clockwise. At this time, the top surface (second side) of the chip 6 faces upward until the guide wheel member 504 slides along the second guide groove 109 into the intersection of the second guide groove 109 and the descending groove 112. At this time, the first rotating shaft 506 is just aligned with the descending groove 112, and the top surface (second side) of the chip 6 is close to the bottom of the second plastic packaging component 103. Then, the trajectory conversion component 2 is controlled to rotate 180° counterclockwise, so that the first conversion groove 205 is aligned with the third guide groove 110 and the two are connected, and the second conversion groove 206 is aligned with the fourth guide groove 111 and the two are connected. At the same time, the plastic packaging processing of the top surface (second side) of the chip 6 is realized by the second plastic packaging component 103 (step 2).

[0043] Next, the entire flip control assembly 5 is controlled to move downward by the lifting cylinder 404 until the bottom of the U-shaped lifting plate 408 abuts against the bottom of the U-shaped mounting frame 401. At this time, the first rotating shaft 506 just abuts against the bottom of the limiting channel 406, and the first rotating shaft 506 just aligns with the intersection of the descending groove 112 and the third guide groove 110. The electromagnet at the position of the third guide groove 110 is controlled to be energized and magnetized. Under the action of the magnetic repulsive force, the corresponding guide wheel 504 is inserted into the third guide groove 110, and then the upper The electromagnet at the position is powered off and demagnetized, so that the upper guide wheel 504 is separated from the descending groove 112 (that is, at this time, only one guide wheel 504 is fitted in the third guide groove 110, and the guide wheels 504 in other directions are in their original state). Then, the power motor 107 controls the power screw 106 to rotate and drive the entire chip conveying mechanism 3 to move with the chip 6 toward the direction of the plastic packaging component 102. When the guide wheel 504 in the third guide groove 110 enters the first conversion groove 205 and rotates along the arc During the process of the slot change 207 sliding into the second conversion slot 206, the support plate 501 rotates 90° clockwise again under the action of the arc-shaped conversion slot 207. Under the joint action of the first transmission wheel 508, the second transmission wheel 510 and the transmission belt 511, the hollow negative pressure portion 503 on the support plate 502 rotates 90° clockwise again. At this time, the top surface (third side surface) of the chip 6 faces upward until the guide wheel member 504 slides along the fourth guide slot 111 into the intersection of the fourth guide slot 111 and the rising slot 113. At this time, the first rotating shaft 506 is just aligned with the rising groove 113, and then the lifting cylinder 404 is used to control the entire flip control component 5 to move upward to complete the reset. At this time, the top surface (the third side) of the chip 6 is close to the bottom of the plastic packaging component 102, and the first rotating shaft 506 is just aligned with the intersection of the first guide groove 108 and the rising groove 113. Then the trajectory conversion component 2 is controlled to rotate 180° in the opposite direction to complete the reset, and at the same time, the plastic packaging component 102 is used to realize the plastic packaging process of the top surface (the third side) of the chip 6 (step three).

[0044] Next, the electromagnet at the position of the first guide groove 108 is controlled to be energized and magnetized again, and the corresponding guide wheel member 504 is inserted into the first guide groove 108 under the action of the magnetic repulsive force. Then, the electromagnet at the lower position is controlled to be de-energized and demagnetized so that the lower guide wheel member 504 is separated from the ascending groove 113 (that is, at this time only one guide wheel member 504 is fitted in the first guide groove 108, and the guide wheel members 504 in other directions are in their original state). Then, the power motor 107 is used to control the power screw 106 to rotate and drive the entire chip conveying mechanism 3 to carry the chip 6 toward the direction close to the plastic packaging component 2 103. Move until the guide wheel member 504 slides along the second guide groove 109 into the intersection of the second guide groove 109 and the descending groove 112. At this time, the first rotating shaft 506 is just aligned with the descending groove 112, and the top surface (fourth side) of the chip 6 is close to the bottom of the second plastic packaging component 103. Then, the trajectory conversion component 2 is controlled to rotate 180° counterclockwise again, so that the first conversion groove 205 is aligned with the third guide groove 110 and the two are connected, and the second conversion groove 206 is aligned with the fourth guide groove 111 and the two are connected. At the same time, the plastic packaging processing of the top surface (fourth side) of the chip 6 is realized through the second plastic packaging component 103 (step four).

[0045] Next, the entire chip conveying mechanism 3 is controlled to move the chip 6 to the position of the plastic packaging component 102 (that is, the chip conveying mechanism 3 returns to the initial position) in the same control method as step three. At this time, the top surface (first side surface) of the chip 6 is facing upward again, and the guide wheel 504 slides along the fourth guide groove 111 to the intersection of the fourth guide groove 111 and the ascending groove 113. At this time, the first rotating shaft 506 is just aligned with the ascending groove 113, thus completing the plastic packaging process of the four sides of the chip 6. Subsequently, the negative pressure generator 512 is used to control the release of the negative pressure environment in the inner cavity of the hollow negative pressure part 503, so that the chip 6 falls off the hollow negative pressure part 503 for collection. After the next chip 6 is adsorbed and fixed on the hollow negative pressure part 503, the plastic packaging process can be continued in the same control method as above.

[0046] Specific embodiment 2, based on specific embodiment 1, as Figure 11 and Figure 13As shown, the elastic guide portion also includes a first moving rod 513 slidably arranged at an eccentric position of the support plate 501, and a connecting plate fixed at one end of the first moving rod 513 is connected to the support plate 501 through a first elastic member 514. The guide wheel member 504 is installed at the other end of the first moving rod 513. Pressure sensors are installed at the top and bottom of the U-shaped mounting bracket 401. When the electromagnet at a certain position on the control support plate 501 is energized and magnetized, the guide wheel member 504 moves and is inserted into the guide groove at the corresponding position under the action of the magnetic repulsive force. At this time, the first elastic member 514 at this position is compressed, and the guide wheel member 504 is installed on the U-shaped mounting bracket 401. A pressure sensor is provided at both the inner top and the inner bottom. When the U-shaped lifting plate 408 is controlled to move downward until the bottom of the U-shaped lifting plate 408 abuts against the inner bottom of the U-shaped mounting frame 401, the pressure sensor at the inner bottom of the U-shaped mounting frame 401 transmits the pressure signal to the control system, which controls the closure of the lifting cylinder 404. When the U-shaped lifting plate 408 is controlled to move upward until the top of the U-shaped lifting plate 408 abuts against the inner top of the U-shaped mounting frame 401, the pressure sensor at the inner top of the U-shaped mounting frame 401 transmits the pressure signal to the control system, which controls the closure of the lifting cylinder 404.

[0047] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, a first guide member 114 is slidingly provided inside the second guide groove 109, a through groove 115 is opened inside the second guide groove 109, a first magnetic plate 116 fixed to the first guide member 114 is provided on the outside of the plastic-sealed carrier 104, a conversion tooth plate 117 engaged with the outer gear ring 204 is fixed on one side of the first magnetic plate 116, a second magnetic plate 118 is fixedly installed on the end of the conversion tooth plate 117, and a second moving rod 119 is fixedly provided on the other side of the first magnetic plate 116; the plastic-sealed carrier 1 04, a first locking plate 120 and a second locking plate 121 are respectively installed. The first locking plate 120 is installed with an electromagnet and a pressure sensor. The second locking plate 121 is installed with an electromagnet that is magnetically attracted to the second magnetic plate 118. The electromagnet on the first locking plate 120 is magnetically attracted to the first magnetic plate 116. The second movable rod 119 slides through the first locking plate 120. The connecting disk fixed at the end of the second movable rod 119 is connected to the first locking plate 120 via a second elastic member 122.In the initial state, the electromagnet on the second locking plate 121 is in a powered and magnetized state. The second magnetic plate 118 is firmly adsorbed on the second locking plate 121 under the action of a strong magnetic attraction. When the guide wheel 504 slides from the second conversion slot 206 into the second guide slot 109, the electromagnet on the second locking plate 121 is controlled to be powered off and demagnetized. At the same time, the electromagnet on the first locking plate 120 is controlled to be powered on and magnetized. As the guide wheel 504 slides along the second guide slot 109 and pushes the first guide member 114 to move synchronously, the first magnetic plate 118 that moves synchronously with the first guide member 114 is 116 drives the second moving rod 119 to move and stretch the second elastic member 122, and at the same time the moving conversion gear plate 117 drives the entire track conversion assembly 2 to rotate counterclockwise until the first magnetic plate 116 abuts against the first locking plate 120 (at this time the first magnetic plate 116 is firmly adsorbed on the first locking plate 120), and the entire track conversion assembly 2 rotates 180 degrees counterclockwise. At this time, the guide wheel member 504 just moves to the intersection of the second guide groove 109 and the descending groove 112. At this time, the first rotating shaft 506 just aligns with the descending groove 112, and the first locking plate 120 is firmly adsorbed on the first locking plate 120. The pressure sensor transmits the pressure signal to the control system, which controls the power motor 107 to be turned off. After the plastic sealing process of a certain side of the chip 6 is completed by the plastic sealing component 2 103, the U-shaped lifting plate 408 is controlled to move downward so that the guide wheel 504 at the intersection of the second guide groove 109 and the descending groove 112 enters the interior of the descending groove 112 until the first rotating shaft 506 is just aligned with the intersection of the descending groove 112 and the third guide groove 110. When the control system receives the pressure signal from the pressure sensor at the bottom of the U-shaped mounting frame 401, it controls the start of the power. Motor 107 drives the entire chip conveyor mechanism 3, carrying the chip 6, back to the position of plastic package assembly 102. It then de-energizes the electromagnet on the first locking plate 120 and simultaneously energizes the electromagnet on the second locking plate 121. Under the elastic restoring force of the second elastic member 122, the conversion gear plate 117 moves in the opposite direction, driving the entire trajectory conversion assembly 2 to rotate 180° in the opposite direction to complete the reset (the entire trajectory conversion assembly 2 is made of lightweight material). At this point, the second magnetic plate 118 is firmly attached to the second locking plate 121 again under the strong magnetic attraction.

[0048] In some embodiments, as Figure 4 and Figure 7As shown, the plastic packaging carrier 104 is provided with an extension channel 123 connected to the fourth guide groove 111, and a moving part 124 is slidably provided inside the extension channel 123. A second guide part 125 is slidably provided inside the fourth guide groove 111. The second guide part 125 is connected to the moving part 124 through a linkage rod 126. A moving plate 127 fixed to the moving part 124 is provided on the outside of the plastic packaging carrier 104. A signal trigger part 128 is fixedly provided on one side of the moving plate 127. The moving plate 127 is connected to the limiting mounting plate 129 on the plastic packaging carrier 104 through a third elastic member 130. A pressure sensor is installed on the limiting mounting plate 129. When the power motor 107 drives the entire chip conveying mechanism 3 to move the chip 6 back to the plastic packaging component 102 position, the chip 6 moves along the fourth guide groove. The guide wheel member 504 sliding inside 111 pushes the second guide member 125 to move, and the movable member 124 moving synchronously with the second guide member 125 drives the movable plate 127 to move and compresses the third elastic member 130 until the signal triggering part 128 rests on the limit mounting plate 129. At this time, the control system receives the pressure signal from the pressure sensor on the limit mounting plate 129, and controls to shut down the power motor 107. The guide wheel member 504 sliding along the fourth guide groove 111 just moves to the intersection of the fourth guide groove 111 and the rising groove 113. When the entire flip control assembly 5 is controlled to move upward and complete the reset by the lifting cylinder 404, the signal triggering part 128 completes the reset under the elastic restoring force of the third elastic member 130, and the second guide member 125 returns to the fourth guide groove 111.
