Description

[0002] In the packaging process, the chip needs to be bonded to the substrate, and sufficient pressure needs to be applied to ensure that there is sufficient contact area and good bonding effect between the chip and the substrate, and the adhesive (such as silver paste, epoxy resin, etc.) is uniformly distributed and fully fills the gap between the chip and the substrate. However, due to the characteristics of the light and thin semiconductor, if a large pressing force is applied during the pressing process, the surface of the semiconductor may be easily arched to form a curved surface, thereby affecting the accuracy of the bonding of the semiconductor and the support and resulting in poor mounting effect. Therefore, the packaging pressure of the light and thin semiconductor needs to be controlled.

[0003] However, compared with the traditional semiconductor packaging device, the use of sensors and control systems for pressure control during packaging requires a complex control system and expensive equipment, which is high in cost. In addition, when batch packaging is performed, the use of the overall packaging structure for packaging cannot well guarantee the packaging pressing force of each semiconductor, and it is inconvenient to adjust the pressing force of the individual pressing structure, resulting in a low yield of semiconductor packaging. Therefore, in order to reduce the cost of the light and thin semiconductor packaging equipment and facilitate the adjustment of the pressing force of the individual pressing structure, and improve the packaging yield of the light and thin semiconductor, the application provides a light and thin semiconductor packaging device.

[0045] Furthermore, the transmission plate 501 is slidably connected to the guide frame 109, the locking gear 504 is meshedly connected to the locking rack 110, the lifting box 7 is provided with an upper driving surface 701 and a lower driving surface 702, the transmission roller 605 is arranged between the upper driving surface 701 and the lower driving surface 702, the lifting box 7 is fixedly connected with an outer supporting block 8, and the top of the lifting box 7 is provided with a through hole 9.

[0046] In specific use, when the packaging process of the thin semiconductor is performed, the driving motor 103 is started, the output end of the driving motor 103 drives the lead screw 104 to rotate, drives the lifting plate 107 to move downwards, drives the lifting box 7 to move downwards, the upper driving surface 701 in the lifting box 7 presses the transmission roller 605 downwards, so that the transmission control structure 6 moves downwards, at the same time, the guide roller 602 presses the transmission plate 501 downwards, so that the balance gear 507 moves downwards, the balance gear 507 drives the press-fitting rack 508 and the transmission rack 509 to move, the press-fitting rack 508 drives the lower pressing column 301 to move downwards through the connecting plate 307, so that the pressing head 306 presses and compresses the semiconductor, and then the semiconductor can be welded and packaged;

[0047] When the pressing rack 508 moves downward, the pressure difference between the pressing rack 508 and the transmission rack 509 is balanced under the action of the balancing gear 507, so that the pressure of the pressing rack 508 on the connecting plate 307 and the pressure of the transmission rack 509 on the connecting block 404 can be balanced. The pressure of the connecting plate 307 causes the pressing head 306 to press the thin and light semiconductor in the packaging substrate 10, and the pressure of the connecting block 404 compresses the adjusting spring 414 through the pressure distribution rod 403, and at the same time drives the hydraulic oil in the pressure tank 401 to flow into the driven tank 410, thereby pushing the driven piston 411 to move. The driven piston 411 pushes the transmission block 604 to move through the push rod 412. When the transmission block 604 moves, it drives the second synchronous rack 606 to move and drives the first synchronous rack 603 to move under the meshing action of the reversing gear 505, so that the driven block 601 and the transmission block 604 can move relatively close to each other, so that the locking ring 608 can move relatively close to each other, and the guide roller 602 moves in the sliding groove 506, the transmission roller 605 rolls on the upper driving surface 701, the locking gear 504 meshes with the locking rack 110 to make the rotating shaft 502 rotate. When the pressure of the pressing rack 508 on the connecting plate 307 compresses the adjusting spring 414 to a predetermined degree, the transmission roller 605 rolls to the through hole 9, so that the upper driving surface 701 cannot press the transmission roller 605 any more. At this time, the locking ring 608 holds the locking key 503 from both sides of the locking key 503, so that the rotating shaft 502 stops rotating, the locking gear 504 cannot rotate, and under the meshing action of the locking gear 504 and the locking rack 110, the power transmission structure 5 is locked and fixed, so that the movement of the lifting plate 107 no longer increases the pressure of the pressing rack 508 on the connecting plate 307, so that the pressure of the pressing head 306 on the semiconductor remains fixed.

[0048] When a group of pressing structures 3 reaches stability, because the transmission roller 605 is located in the through hole 9, the transmission roller 605 is separated from the upper driving surface 701, so that when the lifting plate 107 continues to move downward, each group of pressing structures 3 can be pressurized respectively, so as to facilitate the control of the pressing force during the packaging of each group of thin and light semiconductors.

[0049] When it is necessary to adjust the pressing force of the pressing head 306 on the thin and light semiconductor, the worker rotates the adjusting ring 408, which drives the adjusting piston block 405 to move in the pressure tank 401, thereby adjusting the compression degree of the adjusting spring 414, changing the spring force of the adjusting spring 414, and further changing the pressure of the balancing gear 507 on the pressing rack 508 and the transmission rack 509, so as to realize the adjustment of the pressing force of the thin and light semiconductor.

[0050] After the semiconductor is welded, the driving motor 103 drives the screw rod 104 reversely to rotate, so that the lifting plate 107 and the lifting box 7 are lifted upward, when the outer supporting block 8 contacts the transmission roller 605, the outer supporting block 8 pushes the transmission roller 605 to the two sides, and under the elastic force of the reset spring 609, the locking ring 608 is separated from the two sides of the locking key 503, the locking of the rotating shaft 502 is released, so that the power transmission structure 5 can be lifted upward with the lifting box 7, and the pressing of the semiconductor is released.

[0051] The above is the overall working process of the present application.

[0052] It should be noted that, in this document, the terms such as first and second are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between such entities or operations.
