Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical communication packaging equipment, and particularly to a multi-model chip mounter. BACKGROUND

[0002] Evolution of semiconductor packaging technology: With the development of the semiconductor industry, traditional single-chip packaging mode gradually approaches the physical and economic limit, and advanced packaging technologies such as SiP, Fan-Out, 2.5D / 3D packaging are rapidly developing, and the demand for multi-chip die bonder is increasing. Multi-chip die bonder, as an automated device that precisely bonds multiple chips to a substrate or lead frame during the semiconductor packaging process, plays a key role in high-density integration, heterogeneous integration, and flip-chip packaging scenarios.

[0003] Demand for heterogeneous integration: Chiplet mode, which splits a large chip into multiple small chips and integrates them together through advanced packaging technology, has become the mainstream path for the semiconductor industry to continue Moore's Law. This heterogeneous integration method requires the integration of chips with different process nodes, different functions, different sizes, and different thicknesses in a package, which puts high demands on the precision and coplanarity control of multi-chip die bonder.

[0004] The need to improve production efficiency: Traditional die bonding methods have significant defects for substrates that require the mounting of a large number of chips. For example, the time interval between dipping glue and completing all chip mounting can be long, causing some glue to begin to solidify during the waiting period, thereby affecting the mounting quality and efficiency. Therefore, a multi-chip die bonder is needed to improve mounting efficiency and quality to meet the needs of mass production.

[0005] The need to improve precision: In the field of optical communication modules, the alignment between laser chips and optical fibers must be within microns. If the precision of the die bonder is not sufficient, the optical path will not be aligned, and the signal transmission efficiency will decrease dramatically, or even completely fail. This requires a multi-chip die bonder with higher precision to meet the requirements of chip mounting precision in different application scenarios. SUMMARY

[0061] A plastic basin is also provided between the fifth linear mechanism 509 and the fourth linear mechanism 507, and the plastic basin is fixed on the table 16.

[0062] In this embodiment, the following method is used for application: Step 01: The operator places the rectangular heat sink or substrate into the placement slot of the tray 6, and then places the tray 6 into the feeding placement area of ​​the placement plate 207. During placement, the trays 6 can be stacked on the placement plate 207. After placement, the second cylinder 214 is activated to clamp and fix the tray 6 through the movable clamping plate 215 and the end clamping plate 210. Furthermore, according to the chip model, it is placed in the corresponding waffle box 7, and the waffle box 7 containing the chip is placed in the rectangular slot 417 of the chip placement board 416. The above operations can be completed in one step or in steps, as they are all the starting point of the entire method execution, and therefore are executed within the same step.

[0063] Step 02: Activate the first linear mechanism 203 so that the bottom surface of the top tray 6 is above the third synchronous belt 360, and activate the first cylinder 229 to push the top tray 6 onto the third synchronous belt 360.

[0064] Step 03: Start the second motor 362 to transfer the tray 6 to one end of the mounting plate 345 via the third synchronous belt 360. The inner end of the tray 6 abuts against the inner side of the mounting plate 345 and the pad 370. At this time, the mounting plate 345 is in a high position under the drive of the third cylinder 342.

[0065] Step 04: Activate the fourth cylinder 359 to move the pad 370 upwards, so that the upper wall of the tray 6 abuts against the lower side of the upper cover 346, and the heat sink is located at the rectangular window 347. The first motor 332 is started synchronously, causing the adjusting screw 336 to rotate. When the adjusting screw 336 rotates, the adjusting side plates 337 will move closer to each other and abut against the two sides of the tray 6.

[0066] Step 05: Driven by the first linear motor 302, the second linear motor 305, and the second linear mechanism 307, the needle is first positioned at the location where the chip is to be bonded to the heat sink. Then, by injecting air, adhesive is squeezed from the needle to the chip bonding location. The first linear rotary actuator 319 drives the adhesive applicator 320 to modify the adhesive to match the shape and structure of the chip. During operation, the appropriate adhesive applicator 320 can be picked up from the placement rack as needed. During the dispensing process, the first camera 318 is used to determine the shape and quantity of the adhesive, while the second camera 317 is used to verify whether the selected adhesive applicator 320 is suitable. This improves the accuracy of dispensing. If there is no glue in the dispensing tube 357, the dispensing tube 357 is moved to the storage basin 328 and glue is filled in the dispensing tube 357 by suction. In addition, in order to avoid glue clumping, the storage basin 328 is rotated under the drive of the third motor 326 during the operation, and the glue in the storage cavity is scraped off by the scraper 325 during the rotation to prevent the glue from adhering to the inner wall of the storage cavity.

[0067] Step 06: Activate the third cylinder 342, the fourth cylinder 359, and the first motor 332 to remove the limit on the pallet 6. After that, the pallet 6 will move to the transfer mechanism 508 under the drive of the third synchronous belt 360, and will be transferred to the end of the fourth linear mechanism 507, i.e., near the cross frame 503, under the drive of the fourth linear mechanism 507.

[0068] On the other hand, the fifth linear mechanism 509 is activated so that the first suction cup 530 and the suction nozzle set on the moving block 518 are moved to the chip loading device 4.

[0069] Next, the third linear motor 401, the fourth linear motor 402, the fifth linear motor 412, and the sixth linear motor 413 are activated. The second linear rotary actuator 407 and its suction nozzle 410 pick up the chip and place it onto the corresponding waffle box 7. During chip transfer, the corresponding waffle box 7 can be placed at the location of the first suction cup 530 according to the chip's shape. During operation, the suction nozzle 410 is changed according to the chip's shape, and the transfer process is monitored by the third camera 409, while the changed suction nozzle 410 is confirmed by the fourth camera 411.

[0070] Step 07: Start the seventh linear motor 502, the eighth linear motor 504, the third linear mechanism 521, the third linear rotary actuator 526, and the fourth linear rotary actuator 525. Transfer the chip to the heat sink chip placement position through the pick-up head 527. After placement, the chip needs to be pressed to ensure the placement effect. During the placement process, the fifth camera 528 monitors the placement process and changes the pick-up head 527 according to the shape and structure of the chip. Finally, the placement operation is completed on the heat sink.

[0071] Step 08: Activate the transfer mechanism 508 and transfer the heat sink with the adhered chip to the removal mechanism 506. Transfer the tray 6 to the placement plate 207 through the removal mechanism 506. Activate the first cylinder 229 on the push mechanism 519 to completely push the tray 6 out of the third synchronous belt 360 on the removal mechanism 506, so that the outer end of the tray 6 abuts against the limiting vertical plate 212. When the sensor 218 detects the presence of the tray 6, activate the second cylinder 214 to clamp the tray 6 through the movable clamping plate 215 and the end clamping plate 210, and wait for the tray 6 to be removed.
