Abstract
Description
[Technical field]
[0001] The present invention relates to a bonding apparatus, and more particularly to a bonding apparatus for bonding an adhesive pad to a base member. [Background technology]
[0002] In the traditional IC packaging process, the process involves applying adhesive to the substrate, gluing the die to the substrate, applying thermal glue to the die, and then attaching a heat sink to cover the substrate and die. Alternatively, instead of applying thermal glue, a thermal pad made of thermally conductive material can be used. In this case, the cover film on the lower surface of the thermal pad is peeled off and the lower surface is glued to the upper surface of the die, and then the cover film on the upper surface of the thermal pad is peeled off and the heat sink is glued to the upper surface. However, this process of manually gluing the thermal pad is not suitable for mass production and may lead to product quality degradation.
[0003] Meanwhile, for example, Patent Document 1 discloses a bonding method and bonding equipment for automatically bonding a thermal conductive pad to the upper surface of a die on a substrate. The conventional bonding method and bonding equipment employ a two-step process in which a rotating cylindrical bonding head is brought into contact with a carrier tape to which a thermal conductive pad is bonded to a base member, and then the bonding head returns to its original position and the carrier tape is peeled off from the thermal conductive pad, leaving room for further efficiency improvement.

[0010] Before going into a specific description, components that play the same role in the present invention are assigned the same reference numerals even if they are not exactly the same. Furthermore, terms such as "front", "rear", "left", "right", "upper", "lower", "X direction", "Y direction", and "Z direction" in the following description are used to easily explain the relative positional relationship between each component, and do not limit the configuration of the present invention.
[0011] As shown in FIG. 1, the bonding equipment of the present invention bonds a pad to a base member A, which is, for example, a die arranged on a wafer A1. The wafer A1 is arranged on a film A2 having a surrounding frame A3 surrounding the wafer A1. The wafer A1 is divided into a plurality of base members A arranged in a matrix. The plurality of base members A are arranged on a horizontal plane so as to be spaced apart from each other. In the pad bonding process, as shown in FIG. 2, a bonding pad A4, for example, a thermal conductive pad, is bonded to the upper surface of each base member A.

That is, each adhesive pad A4 is sandwiched between the carrier tape A41 and the cover tape A42, and adjacent adhesive pads A4 in the length direction are arranged with a space between them. The two surfaces of each adhesive pad A4 are releasably attached to the carrier tape A41 and the cover tape A42, respectively. A row of pinholes A411 is formed near each of the peripheries on both sides of the carrier tape A41, and the distance between the two rows of pinholes A411 is wider than the width of the adhesive pad A4, and each adhesive pad A4 is attached to the carrier tape A41 at a location corresponding to the space between the two rows of pinholes A411. This carrier tape A41 is wound around a sleeve A43 having an axial hole A431 to form a tape assembly A44.
[0013] As shown in FIG. 4, one embodiment of the bonding equipment includes a machine base 100, a supply and holding frame 1 having a conveying path 10 extending along the X direction to supply and hold a base member A, a conveying rail means 2 arranged above the conveying path 10 and having a suspending carrier 22 that can move along the Y direction, a bonding device 3, and a lower detection unit 4.
[0014] The supply and holding frame 1 has a fixture 11. The fixture 11 has a plurality of suction parts 111, which are a plurality of annular grooves sharing the same circular center, and exert a suction effect by providing negative pressure. The supply and holding frame 1 has two side frames 12 spaced apart from each other in the Y direction, and two belts 13 arranged on each side frame 12, which together with the corresponding side frame 12 constitute a total of two rails 14. The conveying path 10 is formed between the two rails 14, and conveys the film A2 having the surrounding frame A3 and the wafer A1 shown in FIG. 1 along the X direction and supplies it to the fixture 11. The film A2 is held by the suction parts 111 of the fixture 11 and moves along the Z direction together with the fixture 11.
[0015] The transport rail means 2 has two gantry cranes 21 that are spaced apart from each other in the X direction and cross the transport path 10 .
[0016] Each gantry crane 21 has two support legs 211 extending along the Z direction and arranged on both sides of the transport path 10, and a suspending beam 212 supported by the two support legs 211 so as to extend along the Y direction. A Y-axis driver 213, for example, a linear motor, is arranged on the suspending beam 212. The suspending carrier 22 is arranged on the suspending beam 212 so as to extend along the X direction. Both ends of the suspending carrier 22 are driven by the Y-axis driver 213, respectively, to move along the Y direction relative to the suspending beam 212. An X-axis driver 221, for example, a linear motor, is arranged on the suspending carrier 22.
[0017] The bonding device 3 is movably disposed on the suspending carrier 22 above the supply and holding frame 1. The bonding device 3 is driven by an X-axis driver 221 to move relative to the suspending carrier 22 along the X direction to perform bonding of the bonding pads A4.
[0018] The lower detection unit 4 has an image capture section 41 having a lens for photographing upward and an image sensor (eg, a CCD), and a light source 42 disposed adjacent to the image capture section 41.
[0019] 4 and 5, the fixture 11 has a heating member 112 that indirectly heats the base member A (see FIG. 1) held by the suction part 111. The base 113 has a plurality of vertical spacers 1131. These plurality of vertical spacers 1131 are arranged to support the fixture 11, and are configured to move together with a plurality of rotating shafts 1141 of a moving member 114 arranged below the machine base 100. Each of the rotating shafts 1141 is movably inserted into a plurality of rotating sleeves 1151 of a positioning member 115 arranged on the machine base 100.
[0020] The positioning member 115 is fixed to the positioning table 116 by a plurality of support members 1161. A driver 117 constituted by, for example, a motor is disposed below the positioning table 116, and drives the movement of the base 113 and the fixing device 11 by rotating a screw shaft 1171 to move the moving member 114 along the Z direction.
[0021] As shown in FIG. 6, the bonding device 3 has a conveying means 31 and a bonding means 32 disposed on the conveying means 31 and moving together with the conveying means 31 to perform a bonding process on the adhesive pad A4.
[0022] As shown in Figures 6 and 7, the conveying means 31 includes a plate-shaped vertical conveying table 311, a vertical rail table 312 to which the vertical conveying table 311 is attached so as to be movably mounted along the Z direction, a reel assembly 313 attached to the vertical conveying table 311 so as to be movable along the X direction relative to the vertical conveying table 311, and a deviation calibration assembly 314 that is arranged on the vertical conveying table 311 and drives the deviation of the vertical conveying table 311 relative to the vertical rail table 312.
[0023] The vertical conveying platform 311 has two slide rails 3111 each extending along the X direction and spaced apart from each other in the Z direction, and a screw bolt 3113 disposed between the two slide rails 3111 and driven by a driver 3112. The vertical conveying platform 311 has a passage workspace 3114 and a support bracket 3115 disposed on one side of the passage workspace 3114. The support bracket 3115 has two rotating protrusions 31151 protruding from the vertical conveying platform 311 and positioned respectively above and below the passage workspace 3114, and a rotating shaft 31152 extending along the Z direction and connected to the two rotating protrusions 31151. The vertical conveying platform 311 further has an upper detection unit 3116. The upper detection unit 3116 has an image capture unit 31161 having a lens and an image sensor for taking pictures downward, and a light source 31162 disposed below the image capture unit 31161.
[0024] The vertical rail base 312 is disposed on the suspending carrier 22 of the conveying rail means 2, and has two slide rails 3121 extending along the Z direction, and a slide sheet 3123 driven by a drive motor 3122 to move along the slide rails 3121. The slide sheet 3123 has a protruding sheet 3124 which penetrates the passage working space 3114 of the vertical conveying base 31 along the Y direction, and to which the rotating shaft 31152 is rotatably attached, thereby enabling the slide sheet 3123 to move in the Z direction while holding the vertical conveying base 311.
[0025] The reel assembly 313 has a plate-shaped vertical reel base 3131 that is movably attached to the slide rail 3111 of the vertical conveyor base 311 and moves along the X direction together with the screw bolt 3113, a first reel 3132 that is rotatably attached to the vertical reel base 3131 and winds up the carrier tape A41 (see FIG. 3) from which the cover tape A42 and the adhesive pad A4 are peeled off, and a second reel 3133 that is rotatably attached to the vertical reel base 3131 and winds up the cover tape A42 peeled off from the carrier tape A41. Furthermore, the reel assembly 313 has a driver 3134 that is, for example, an air cylinder that operates along the Z direction, and an elastic member 3135 that is, for example, a compression spring.
[0026] The deviation calibration assembly 314 has a drive motor 3141 and a linkage means 3142 constituted by a four-bar link mechanism driven by the drive motor 3141. A fixed bar 31421 is attached to the output end of the drive motor 3141, and a rotating shaft 31152 attached to an axial hole 31423 formed in a movable bar 31422 parallel to the fixed bar 31421 extends along the Z direction. Two holders 3143 arranged on both sides of the drive motor 3141 in the X direction are fixed to both sides of a protruding sheet 3124 of the vertical rail base 312, so that the deviation calibration assembly 314 moves together with the protruding sheet 3124.
[0027] As shown in Fig. 8 and Fig. 9, the bonding means 32 has a plate-shaped vertical bonding base 321, a supply reel 322 rotatably attached to one side of the vertical bonding base 321, and a positioning base 323 attached to the opposite side of the one side of the vertical bonding base 321. The tape assembly A44 is disposed on the supply reel 322 (see Fig. 11), and is supplied to the supply path by operating an operation unit which is a part of the tape assembly A44 pulled out from the supply reel 322. The supply reel 322 rotatably passes through the vertical bonding base 321 along the Y direction, and has a reel shaft 3221 attached to the positioning base 323. The reel shaft 3221 is intermittently rotated by a driver 3231, for example a motor, which is disposed on the positioning base 323. The positioning base 323 is fixedly attached to the lower part of the vertical reel base 3131 of the reel assembly 313 (see Fig. 7), so that the bonding means 32 can move together with the reel assembly 313 along the X direction. In addition, when the first reel 3132 and the second reel 3133 are held immovably relative to the supply reel 322, the vertical adhesive base 321 can swing about the rotation axis of the reel shaft 3221 relative to the positioning base 323 and the vertical reel base 3131 (see FIG. 7). Furthermore, the adhesive means 32 has a shift lever 324 at the bottom of the vertical adhesive base 321 (see FIG. 9). The shift lever 324 extends from the vertical adhesive base 321 along the Y direction away from the supply reel 322. The shift lever 324 is driven by a driver 3241, for example an air cylinder, disposed on the vertical adhesive base 321, and moves relative to the vertical adhesive base 321 along the Z direction and away from the supply reel 322. Furthermore, an adjustment member 3211 disposed on one side of the vertical adhesive base 321 is adjacent to the supply reel 322 and has a vertical male screw portion. The bonding means 32 further includes a carrier bracket 325 disposed on the same side of the vertical bonding table 321 as the supply reel 322 .
[0028] As shown in FIG. 10, the carrier bracket 325 is configured to define a lower input path 3251 through which the operating part of the tape assembly A44 passes, and an upper output path 3252 through which the operating part of the tape assembly A44 passes. Specifically, a plurality of converting rollers 3253 are attached to the lower input path 3251, and one converting roller 3254 is attached to the upper output path 3252. A guide wheel 326 extending in the Y direction is disposed on the vertical adhesive base 321 so as to be located on the upper output path 3252. The guide wheel 326 has two encircling pin portions 3261 on two end faces, and a rotating portion 3262 is disposed between the two encircling pin portions 3261. The guide wheel 326 is driven to rotate by a drive motor 3263. A tape pressing bracket 327 is disposed so as to be adjacent to the guide wheel 326. The tape pressing bracket 327 is rectangular and includes a central shaft 3272 extending along the Y direction, two wheel sleeves 3271 attached to both ends of the central shaft 3272 and corresponding to the two surrounding pin portions 3261, and two pressing shafts 3273 disposed on both sides of the central shaft 3272 and extending in the Y direction. Two connectors 3274 are disposed on both ends of the central shaft 3272. One connector 3274 adjacent to the vertical adhesive base 321 is fixed to a slider 3276 slidable along two slide rails 3275 on the vertical adhesive base 321, so that the tape pressing bracket 327 can move radially away from / closer to the guide wheels 326. In addition, the engagement pin 3277 arranged on the inside of this connector 3274 can be elastically inserted into a lock hole 3278 formed between two slide rails 3275 on the vertical adhesive base 321, thereby maintaining the tape holding bracket 327 close to the guide wheel 326.
[0029] The carrier bracket 325 has a side mounting part 3256 separated from the vertical bonding base 321 across the supply space 3255, and a plurality of cross members 3257 arranged between the side mounting part 3256 and the vertical bonding base 321. The conversion roller 3253 is also arranged between the side mounting part 3256 and the vertical bonding base 321. The uppermost one of the plurality of cross members 3257 has a first connecting member 32571 and a second connecting member 32572, and the lower end of the cylinder piston 31341 of the driver 3134 and the lower end of the elastic member 3135 (see FIG. 7) are connected to the first connecting member 32571 and the second connecting member 32572, respectively, thereby connecting the bonding means 32 to the reel assembly 313, and moving the bonding means 32 in the Z direction in response to the movement of the reel assembly 313. The bonding means 32 further includes a mounting bracket 328 disposed at an end of the carrier bracket 325 remote from the supply reel 322 (see FIG. 8). A bonding head 3281 formed in a rod shape and extending in the Y direction is attached to the mounting bracket 328. The bonding head 3281 is disposed within the supply path and within the supply space 3255, and is located at the intersection of the lower input path 3251 and the upper output path 3252. The lower input path 3251 and the upper input path 3252 intersect with each other at an angle of less than 90 degrees.
[0030] As shown in FIGS. 11 to 13, the vertical adhesive base 321 of the adhesive means 32 can swing around the rotation axis of the reel shaft 3221.
[0031] As shown in FIG. 12, in a normal state, the adhesive head 3281 is disposed on the left side in the clockwise direction of a vertical line Z passing through the reel shaft 3221 along the Z direction. A line L passing through the adhesive head 3281 and the reel shaft 3221 intersects with the vertical line Z at an angle θ within a range of 45 degrees to 90 degrees. The cylinder piston 31341 of the driver 3134 is spaced from the reel shaft 3221 and operates to push the adhesive means 32 downward in the counterclockwise direction as viewed from the reel shaft 3221 to apply a first torque to the adhesive head 3281, thereby abutting the adjustment member 3211 against the lower edge of the vertical reel base 3131. At this stage, the adhesive head 3281 is located below the working position 3282 in the clockwise direction as viewed from the reel shaft 3221. At this time, the elastic member 3135, which is a compression spring, supports a part of the weight of the adhesive means 32. Therefore, the elastic member 3135 applies a second torque in a clockwise direction as viewed from the reel shaft 3221 to the bonding head 3281. The first torque opposes the second torque. The displacement of the bonding head 3281 by the first torque determines the height of the working position, and this working position is adjustable by the adjustment member 3211.
[0032] When the tape assembly A44 is wound onto the supply reel 322, the cover tape A42 is peeled off from the carrier tape A41 and wound onto the second reel 3133. The carrier tape A41, with the adhesive pad A4 facing downward, is supplied to pass through each conversion roller 3253 and the adhesive head 3281 along the lower input path 3251, and then passes through the encircling pin portion 3261 of the guide wheel 326 along the upper output path 3252, and is wound onto the first reel 3132. As shown in FIG. 11, the pressing shaft 3273 operates to press down the carrier tape A41 passing through the guide wheel 326.
[0033] As shown in FIG. 4, FIG. 12, and FIG. 13, in the bonding process, the upper detection unit 3116 photographs an image of the base member A downward, and then the bonding device 3 approaches the lower detection unit 4, so that the lower detection unit 4 detects the adhesive pad A4 on the lower side of the carrier tape A41 upward. In the process of photographing the image of the adhesive pad A4, as shown in FIG. 14, the shift lever 324 disposed between the supply reel 322 and the bonding head 3281 presses the operation part of the carrier tape A41 downward along the lower input path 3251 to shift the operation part of the carrier tape A41 from an oblique state to a horizontal state (see dotted line) on the input side. Therefore, the lower detection unit 4 can accurately detect the posture of the adhesive pad A4. Then, the shift lever 324 moves upward to return to the original position, and the carrier tape A41 returns to the oblique state (it is also possible to maintain the carrier tape A41 in a horizontal state in some cases). When the upper detection unit 3116 and the lower detection unit 4 detect the presence of a deviation between the posture of the base member A and the adhesive pad A4, the deviation calibration assembly 314 moves the vertical conveying table 311 diagonally and horizontally relative to the vertical rail table 312 to displace the adhesive head 3281 and calibrate the posture of the adhesive pad A4 to correspond to the base member A.
[0034] 12 and 13, the vertical rail base 312 drives the vertical conveyor base 311 downward to move the reel assembly 313 and the bonding means 32 to a predetermined position above the base member A. At this stage, one surface side of the bonding pad A4 is aligned with and in contact with the bonding head 3281 at the working position. The upward reaction force generated as a result of the downward movement of the bonding head 3281 along the Z direction, which presses the carrier tape A41 and the bonding pad A4 against the base member A, causes the cylinder piston 31341 of the driver 3134 to rise slightly to relieve the downward pressing force, and the bonding head 3281 can be turned upward in the clockwise direction to move to the bonding position 3283. At this stage, the adjustment member 3211 is away from the vertical reel base 3131. Therefore, the operation portion of the carrier tape A41 passes through the adhesive head 3281, and is partitioned by the adhesive head 3281 into an input side on the lower input path 3251 and an output side on the upper output path 3252 side.
[0035] The supply movement of the carrier tape A41 stops at the lower input path 3251, and the vertical reel base 3131 of the reel assembly 313 moves along the slide rail 3111 (see FIG. 7) in the X direction to move the first reel 3132, the second reel 3133 and the bonding means 32 along the X direction. The bonding head 3281 moves in the X direction while rolling, passes the carrier tape A41, indirectly presses the bonding pad A4 below the carrier tape A41, and rolls from the side adjacent to the upper output path 3252 to the opposite side of the lower input path 3251. At this stage, the guide wheel 326 and the first reel 3132 take up the carrier tape A41, and the bonding pad A4 is transported by the carrier tape A41 to the underside of the bonding head 3281. Therefore, when the carrier tape A41 is moved from the lower input path 3251 to the upper output path 3252, one surface side of the adhesive pad A4 is separated from the carrier tape A41, while the other surface side of the adhesive pad A4 is adhered to the upper surface of the base member A.
[0036] As shown in Fig. 15 and Fig. 16, in a modified embodiment of the present invention, the bonding equipment includes a tape assembly having a carrier tape G and a bonding pad. For example, the carrier tape is formed without pinholes and relatively narrow. A driver 51 formed of an air cylinder is disposed on the vertical bonding table 321 adjacent to the guide wheel 326. The tape pressing member 52 has a pressing roller 521 that is driven by the driver 51 and abuts against and presses the carrier tape G passing through the rotating part 3262. The stabilizing member 53 disposed on the mounting bracket 328 so as to be located in the upper output path 3252 has a passage 531 through which the carrier tape G supplied from the lower input path 3251 can pass. The carrier tape G is supplied to the upper output path 3252 by passing under the bonding head 3281 and through the passage 531.
[0037] As shown in FIG. 17, in another embodiment, the bonding equipment is for bonding a bonding pad to a die H2 of a substrate H1. As shown in FIG. 4, the bonding equipment includes a conveying rail means 2 and a bonding device 3 similar to the above embodiment. The bonding equipment includes two supply and holding frames 6 arranged on a machine base 100 so as to be spaced apart from each other in the X direction. Each supply and holding frame 6 includes a fixture 61. The fixture 61 includes a plurality of rectangular suction sections 611, each of which is configured to provide negative pressure. Each supply and holding frame 6 includes two side frames 62 each of which is spaced apart from each other in the X direction, and two belts 63 respectively arranged on the two side frames 62. Each side frame 62 and the belts 63 arranged on the side frames 62 together define two rails 64. A conveying path 60 extending in the Y direction is formed between the two rails 64. The conveying path 60 can convey a base member H having a die H2 and bond it to the substrate H1 at the fixture 61. The base member H is held by the suction portion 611 of the fixture 61 and can move in the Z direction together with the fixture 61. The movable rail bracket 7 arranged at the tip of the two supply and holding frames 6 can move on the X-direction rail base 8 along the X direction. The movable rail bracket 7 has two side frames 71 spaced apart from each other in the X direction and two belts 72 arranged on the two side frames 71, respectively. The two belts 72 define a total of two rails 73 together with the corresponding side frames 71. The conveying path 70 formed between the two rails 73 extends in the Y direction. The movable rail bracket 7 moves along the conveying path 70 together with the conveying path 60 of any one of the supply and holding frames 6.

[0038] As shown in the figure, the adhesive head 3281 is disposed in the supply path and divides the operation section of the carrier tape A41 into an input side and an output side. The adhesive head 3281 moves obliquely with respect to the rotation axis of the reel shaft 3221 of the supply reel 322 to reach the working position 3282. The adhesive pad A4 is separated from the carrier tape A41 and adhered to the base member A. Therefore, when the carrier tape A41 is supplied, the adhesive pad A4 is separated from the carrier tape A41 and adhered to the base member A by the adhesive head 3281, so that there is no need to rotate the adhesive head 3281 back and forth for adhesion efficiency.
