Description

Technical Field

[0002] Chip bonding is the core link of semiconductor manufacturing. It connects different chips or wafer layers through physical methods to achieve three-dimensional integration and packaging of circuits.

[0003] In specific implementation, the chip is first fixed to the lead frame, and then the bonding wire (commonly used as metal wire) uses heat energy, pressure or ultrasonic energy to form a fusion or pressure welding connection between the contact point of the chip and the conductive pin of the frame, thereby establishing an electrical path between the chip and the external circuit board.

[0004] The existing bonding equipment consists of a feeding part, a bearing part, a force applying part, a heating part, a bonding part and a wire pay-off part. The wire pay-off part has a built-in winding roller on which the bonding wire is wound.

During this period, the alignment of the ends of the two sections of bonding wire after cutting is particularly critical. If the first cutting fails to align or overlap occurs, repeated processing is required.

[0027] Please refer to Figure 1 and Figure 10-13The clamping assembly includes a carrier 70 fixedly connected to the work cabinet 10. The carrier 70 is fixedly connected to two slide rails 71 of different sizes. The size of the inner slide rail 71 on the carrier 70 is smaller than the size of the outer slide rail 71 on the carrier 70. The distance between the two slide rails 71 is always consistent. Two groups of electric sliders are arranged in the two slide rails 71, each group is composed of two electric sliders. Two adjacent electric sliders in the two slide rails 71 are fixedly connected to a sliding table 72. The sliding table 72 is a carrier table for carrying chips. The sliding table 72 is slidably connected to two fifth sliding members 73 and two sixth sliding members 74 distributed in a mirror image. The two mirror-distributed fifth sliding members 73 and the two adjacent and mirror-distributed sixth sliding members 74 are cross-distributed. The two mirror-distributed fifth sliding members 73 are squeezed and matched with the adjacent sixth sliding member 74. A spring is provided between the fifth sliding member 73 and the adjacent sliding table 72. This spring is used to drive the adjacent fifth sliding member 73 to reset and move. A spring is provided between the sixth sliding member 74 and the adjacent sliding table 72. This spring is used to drive the adjacent sixth sliding member 74 to reset and move. Two extrusion members 75 with mirror-distributed left and right are fixed to the right side of the supporting platform 70. The extrusion member 75 is squeezed and matched with the adjacent sixth sliding member 74.

[0028] Before using this device to bond the chip, the staff starts all the electric sliders in the two slide rails 71. Taking the movement process of two adjacent electric sliders as an example, the two adjacent electric sliders drive the adjacent sliding tables 72 to move counterclockwise along the two slide rails 71. During this process, the staff places the chip on the sliding table 72 located on the left side of the carrier table 70, and the two adjacent electric sliders drive the adjacent sliding tables 72, the carrier table 70 and its accessories to move.

[0029] When two adjacent electric sliders drive the adjacent sliding tables 72 to move to the front curved parts of the two slide rails 71, the two adjacent electric sliders drive the adjacent sliding tables 72 to change directions (change the front and rear directions of the sliding tables 72), so that the two adjacent electric sliders drive the adjacent sliding tables 72 to move toward the right rear side of the supporting platform 70.

[0030] When two adjacent electric sliders drive the adjacent sliding tables 72 to move until the two adjacent sixth sliding members 74 contact the two adjacent extrusion members 75 respectively, the sixth sliding member 74 is squeezed by the adjacent extrusion members 75 to move in the direction of the chip. During the movement of the sixth sliding member 74, the adjacent spring and the adjacent fifth sliding member 73 are squeezed. Through the movement of the fifth sliding member 73 and the adjacent sixth sliding member 74, the chip is centered and fixed, and the chip is stably clamped and fixed in a clamping manner.

[0031] After the chip is fixed, the two adjacent electric sliders stop moving temporarily, and the bonding gun 11 performs bonding operation on the chip (the bonding process is consistent with the existing method). During the chip bonding process, the rotating part 13 on the right drives the adjacent wire release part 14 to rotate, and then the delivery part 17 transfers the bonding wire on the wire release part 14 to the bonding gun 11, thereby completing the transfer of the bonding wire.

[0032] When the chip mentioned above is bonded, the two adjacent electric sliders drive the sliding table 72, the chip and its accessories to move to the rear side. When the sliding table 72 drives the two adjacent sixth sliding members 74 to release from the adjacent extrusion members 75, the two adjacent sixth sliding members 74 are reset and moved under the action of adjacent springs to lose the extrusion of the adjacent fifth sliding member 73. The fifth sliding member 73 is reset and moved under the action of adjacent springs. The clamping and fixation of the chip are released by the reset movement of the sixth sliding member 74 and the fifth sliding member 73, thereby facilitating the removal of the chip.

[0033] When the bonding wire on the wire release component 14 is in the process of being released, the coil turn number measuring module 15 monitors the bonding wire on the wire release component 14. When the bonding wire on the wire release component 14 is used up, the coil turn number measuring module 15 transmits a signal to the remote control terminal, and the remote control terminal controls the delivery component 17 to no longer deliver the bonding wire, and no longer controls the bonding gun 11 to bond the chip.

[0034] When the bonding wire on the wire release component 14 is used up, the remote control terminal controls all the electric sliders to stop moving, and then the remote control terminal controls the telescopic part of the first electric drive component 24 to move forward. The telescopic part of the first electric drive component 24 drives the first extrusion frame 30 to move forward through the spring, so that the first extrusion frame 30 squeezes the two moving parts 31, and the two moving parts 31 then move toward each other crosswise. The adjacent tension springs are stretched during the movement of the moving parts 31. The bonding wire is limited and fixed during the movement of the two moving parts 31. Under the action of the two moving parts 31 moving toward each other, the bonding wire is gradually moved toward the middle of the moving part 31 during the extrusion process, thereby completing the limitation of the position of the bonding wire.

[0035] When the two moving parts 31 move to a position sufficient to fix the bonding wire, the telescopic part of the first electric drive part 24 squeezes the adjacent springs and slides along the first extrusion frame 30. During the forward movement of the telescopic part of the first electric drive part 24, the first connecting rod 21 is squeezed forward, so that the first connecting rod 21 drives the two first shearing parts 22 to move forward. During the forward movement of the first connecting rod 21, it moves forward along the slide groove 23 located in the middle and squeezes the adjacent springs. Under the action of the first connecting rod 21 moving forward, the first connecting rod 21 drives the two first shearing parts 22 to move forward synchronously, and under the action of the first shearing part 22 sliding along the adjacent slide groove 23, the two first shearing parts 22 are rotated along the first connecting rod 21, so as to realize the cutting of the bonding wire around the first sliding part 16, so that the bonding wire around the first sliding part 16 can be kept at a fixed length.

[0036] After the cutting of the bonding wires around the first sliding member 16 is completed, the electric slider on the lower inner side of the supporting plate 12 drives the first sliding member 16 and its accessory parts to move to the left. After the first sliding member 16 moves to the left until the telescopic part of the first electric drive member 24 is no longer in contact with the first connecting rod 21, the first connecting rod 21 drives the two first shearing members 22 to move backward under the action of the adjacent springs. Under the action of the first shearing member 22 moving along the adjacent slide groove 23, the first shearing member 22 is reset and rotated along the first connecting rod 21.

[0037] During the process of the first sliding member 16 driving its accessory parts to move to the left side (taking the movement process of the accessory parts on the left L-shaped sliding frame 43 as an example), the second electric drive member 41 is controlled by the remote control terminal to move the first-level telescopic part downward, and the first-level telescopic part of the second electric drive member 41 drives the second extrusion frame 42 to move downward. Under the action of the support force provided by the spring between the two second shearing members 46 to the two is less than the support force provided by the adjacent tension spring of the L-shaped sliding frame 43, the second extrusion frame 42 squeezes the adjacent third extrusion frame 44 to move to the right side. In the process of the third extrusion frame 44 moving to the right side, it squeezes the two adjacent second shearing members 46, so that the two adjacent second shearing members 46 rotate along the adjacent second connecting rods 45 and squeeze the adjacent springs. In the process of the rotation of the two adjacent second shearing members 46, the bonding wires around the third extrusion frame 44 are cut.

[0038] When the second extrusion frame 42 squeezes the third extrusion frame 44 to the point where the two adjacent second shearing pieces 46 are sufficient to cut the surrounding bonding wires, the left sides of the two adjacent second shearing pieces 46 are respectively located in the pits in the third extrusion frame 44. At this time, the third extrusion frame 44 is squeezed to the extreme position, and the first-level telescopic part of the second electric drive component 41 drives the third extrusion frame 44 and the L-shaped sliding frame 43 and its accessory parts to move downward synchronously (the adjacent tension springs are stretched during the downward movement of the L-shaped sliding frame 43).

[0039] When the first-stage telescopic part of the second electric drive component 41 moves to the extreme position (the first-stage telescopic part of the second electric drive component 41 extends out to the extreme length), all the accessory parts on the upper side of the L-shaped sliding frame 43 are located below the first sliding component 16, and then the second telescopic part of the second electric drive component 41 is controlled by the remote control terminal, so that the second telescopic part of the second electric drive component 41 drives the adjacent third sliding component 61, the adjacent first oil storage component 60, the adjacent sliding block 50, the adjacent second sliding component 51 and the first-stage telescopic part of the second electric drive component 41 to move downward synchronously through the connecting plate (at this time, the resistance to the movement of the sliding block 50 is less than the extrusion force provided by the adjacent spring in the first oil storage component 60 on the adjacent third sliding component 61).

[0040] During the movement of the above parts, when the first sliding member 16 drives its attached parts to move to the middle of the first sliding member 16 and is on the same vertical line as the adjacent sliding block 50 , the two squeezing blocks 52 on the first sliding member 16 are respectively located on the left and right sides below the adjacent sliding block 50 .

[0041] When the second telescopic part of the second electric drive component 41 drives the adjacent sliding block 50 to move to its lower side and fit with the supporting plate 12, the bonding wire on the first sliding component 16 contacts the bonding wire on the adjacent sliding block 50, and the second telescopic part of the second electric drive component 41 drives the third sliding component 61 to move downward through the connecting plate (the adjacent spring is squeezed during the movement of the third sliding component 61), so that the hydraulic oil in the first oil storage component 60 is respectively transported to the two adjacent second oil storage components 62 through two adjacent connecting pipes, so that the two adjacent fourth sliding components 63 move toward each other, and the bonding wires on the adjacent sliding blocks 50 and the bonding wires on the first sliding component 16 are squeezed and fixed, and then the two bonding wires mentioned above are processed by the welding equipment external to the sliding block 50, so that the two bonding wires are combined into one, thereby realizing unmanned connection of the bonding wires.

[0042] During the unmanned connection of the bonding wire, the staff removes the old wire-releasing component 14 (the wire-releasing component 14 located on the right side in the present invention), and then places the new wire-releasing component 14 on the adjacent rotating component 13. The staff then places the bonding wire on the new wire-releasing component 14 between the adjacent sliding blocks 50 and the second sliding component 51, thereby completing the replacement of the spare wire-releasing component 14.

[0043] When the processing of the bonding wire is completed, the bonding wire on the sliding block 50 and the bonding wire on the first sliding member 16 are combined into "a complete bonding wire". At this time, the second telescopic part of the second electric drive part 41 on the right is moved upward and reset by the remote control terminal. The first oil storage part 60 slides relative to the third sliding member 61 under the action of the adjacent spring, so that the hydraulic oil in the two adjacent second oil storage parts 62 enters the first oil storage part 60 through the adjacent connecting pipes respectively, so that the two fourth sliding members 63 no longer squeeze the bonding wire. Subsequently, the electric slider located on the lower side of the carrier plate 12 is controlled by the remote control terminal to drive the first sliding member 16 and its attached parts to move toward the middle of the carrier plate 12. During the process of the first sliding member 16 driving the two extrusion blocks 52 to move to the right and reset, the extrusion block 52 on the left squeezes the adjacent second sliding member 51, so that the second sliding member 51 moves to the front side to break away from the fixation of the adjacent bonding wire (the adjacent tension spring is stretched during the movement of the second sliding member 51).

[0044] When the bonding wire is out of contact with the adjacent second sliding member 51 and the sliding block 50, the extrusion block 52 no longer squeezes the adjacent second sliding member 51, and the second sliding member 51 is reset and moved under the action of the adjacent tension spring. After the first sliding member 16 and its accessory parts move to the middle of the carrier plate 12, the replacement of the bonding wire is completed, and then the rotating member 13 on the left is controlled to rotate by the remote control terminal to release the bonding wire on the adjacent wire release member 14, and finally the delivery member 17 delivers the bonding wire to restore the bonding to the chip.

[0045] After the first sliding member 16 and its attached parts move to the middle of the carrying plate 12, the telescopic portion of the second electric drive member 41 on the left side drives the third sliding member 61, the adjacent sliding block 50 and its attached parts to move upward through the adjacent connecting plate. After the telescopic portion of the second electric drive member 41 on the left side retracts to the basic state, the telescopic portion of the first electric drive member 24 on the left side drives the second extrusion frame 42 to move upward and reset, and the L-shaped sliding frame 43 moves and resets under the action of the adjacent tension spring. The above-mentioned parts move to Figure 7 and Figure 8 After the state is reached, the movement stops, at which time the third extrusion frame 44 no longer extrudes the two adjacent second shearing members 46, and the two adjacent second shearing members 46 are reset under the action of the adjacent springs.

[0046] When the bonding wire needs to be replaced again, the above steps can be repeated. When the chip no longer needs to be bonded, the staff can turn off the above-mentioned power components.

[0047] Example 2: Based on Example 1, please refer to Fig.12 and Fig.13, and also includes an airbag 8, which is fixed to the upper side of the sliding table 72. The airbag 8 is used to provide a flexible pad for the lower side of the chip. The two sliding tables 72 are jointly provided with a third fixing component for fixing the chip in a negative pressure fixing manner (in the present invention, the number of sliding tables 72 is only for example and not limited).

[0048] Please refer to Figure 10-Figure 14 The third fixing component includes an air storage member 90 fixedly connected to the lower side of the adjacent sliding platform 72. The sliding platform 72 is provided with a nine-square slot 9. The air storage member 90 is connected to the adjacent nine-square slot 9 through a connecting pipe. A sealing member 91 is sealed and slidably connected in the air storage member 90. The sealing member 91 is made of metal. The air storage member 90 is provided with air holes. Two magnetic suction members 92 distributed in a mirror image are fixedly connected in the air storage member 90. The two magnetic suction members 92 distributed in a mirror image are magnetically matched with the adjacent sealing member 91. The magnetic suction member 92 is an annular magnet. The magnetic suction member 92 is used to magnetically attract the adjacent sealing member 91. The two The slide rails 71 are all fixedly connected with an extrusion plate 93, and the extrusion plate 93 is provided with an inclined surface. The extrusion plate 93 is extruded and matched with the two seals 91, and the seals 91 are extruded and matched with the inclined surfaces on the adjacent extrusion plates 93. Through the cooperation between the seals 91 and the inclined surfaces on the adjacent extrusion plates 93, the seals 91 slide in the adjacent gas storage parts 90 and extract the gas in the nine-grid grooves 9 to create a negative pressure fixed environment between the chip and the adjacent nine-grid grooves 9. Under the action of the nine-grid grooves 9, the suction force of the negative pressure extraction is evenly distributed to avoid adsorption of a single position of the chip, which causes deformation of the chip.

[0049] When the sliding table 72 transports the chip, the chip contacts the upper side of the airbag 8, providing a flexible pad for the lower side of the chip to prevent the chip from being squeezed by the adjacent fifth sliding member 73 and the sixth sliding member 74, causing hard friction between the chip and the upper side of the sliding table 72, resulting in chip damage and other problems.

[0050] After the chip is placed on the upper side of the sliding table 72, the chip is located on the upper side of the adjacent nine-grid slot 9. At this time, the two electric sliders drive the sliding table 72 to move until the seal 91 contacts the inclined surface of the right extrusion plate 93, so that the seal 91 moves to the side away from the adjacent extrusion plate 93. During the movement of the seal 91, the gas between the chip and the nine-grid slot 9 is extracted through the connecting pipe to create a negative pressure fixed environment between the chip and the adjacent nine-grid slot 9. Under the action of the nine-grid slot 9, the suction force of the negative pressure extraction is evenly distributed to avoid adsorption of a single position of the chip, which causes deformation of the chip.

[0051] After the sealing member 91 is squeezed by the adjacent squeezing plate 93 until it contacts the adjacent magnetic attraction member 92 , the sealing member 91 is fixed to ensure the sealing degree between the chip and the nine-grid slot 9 .

[0052] When the chip is bonded and transferred from the right side to the left side of the carrier 70, the extrusion plate 93 located on the inner slide rail 71 squeezes the adjacent seal 91, so that the seal 91 is separated from the adjacent magnetic component 92 (thereby making the seal 91 contact with another adjacent magnetic component 92, thereby ensuring that the seal 91 does not slide freely after being moved and reset), and pushes the gas in the adjacent gas storage component 90 back into the space between the chip and the adjacent nine-square grid slot 9 through the connecting pipe, thereby releasing the fixation of the chip and allowing the chip to be taken out.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
