Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of semiconductor processing, and in particular to a mounting mechanism and a crystal bonding machine. Background Art
[0002] Eutectic bonding technology is a metal-to-metal fusion bonding technique. It uses various heating methods to melt the alloy layer between eutectic chips, or between the eutectic chip and the base or lead frame, thereby forming a strong metal-to-metal fusion bond. Compared to traditional bonding methods, metal-to-metal bonding increases bond strength, reduces bond resistance, and improves thermal conductivity.
[0003] At present, when performing the eutectic process, eutectic is usually achieved by substrate heating or nozzle assembly heating. When the substrate heating method is used, since the chips need to be eutecticated on the top of the substrate in sequence, the chips on the top of the substrate will be heated multiple times, causing the eutectic parts of the previously installed chips and the substrate to melt again, affecting the eutectic quality. Although the nozzle assembly heating method can avoid repeated heating of the chip and the substrate at the corresponding position, the existing device integrates the heating structure into the mounting mechanism, which not only causes the structure of the mounting mechanism to be bloated, but also interferes with the disassembly and assembly of the nozzle assembly, making it impossible to adjust the specifications of the nozzle assembly in time according to the needs of the chip, resulting in a decrease in work efficiency.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.
[0038] like Figure 1-Figure 7 As shown, a mounting mechanism according to an embodiment of the present invention includes: a main body component 1, a nozzle component 2 and a connecting component 3; the main body component 1 includes a mounting seat 11 and a first conductive member 12, the mounting seat 11 has a mounting surface 111, the first conductive member 12 is provided on the mounting seat 11, the first conductive member 12 has a first conductive end 121, and the first conductive end 121 is located on the mounting surface 111; the nozzle component 2 includes a base 21, a heater 22, a first conductive member 23 and an adsorption member 24, the base 21 is detachably mounted on the mounting surface 111 through the connecting component 3, the heater 2 2 is provided on a side of the base 21 away from the mounting surface 111. The first conductive member 23 is provided on the base 21 and is electrically connected to the heater 22. The first conductive member 23 has a first conductive end 2311, which is located on the side of the base 21 facing the mounting surface 111. The adsorption member 24 is provided on the base 21. The adsorption member 24 has an adsorption end, which extends from the base 21 and is provided on the heater 22. The adsorption end is used to adsorb the chip. When the base 21 is installed on the mounting surface 111, the first conductive end 2311 can be electrically connected to the first power end 121.
[0039] Based on the above scheme, the present application sets a first conductive member 23 and a first power-carrying member 12 so that the heater 22 can be electrically connected in a contact conductive manner. Specifically, after the nozzle assembly 2 is installed to the main assembly 1, the first conductive end 2311 of the first conductive member 23 can contact the first power-carrying end 121 of the first power-carrying member 12, and the first power-carrying member 12 transmits current to the heater 22 through the first conductive member 23 to realize powering of the heater 22. On this basis, the present application integrates the heater 22 on the base 21 of the nozzle assembly 2 so that when the nozzle assembly 2 and the main assembly 1 are disassembled and assembled through the connecting assembly 3, the heater 22 and The base 21 can be disassembled and assembled together, and the setting of the heater 22 will not affect the disassembly and assembly of the base 21, so that the present application can not only heat the suction nozzle assembly 2, but also conveniently complete the replacement of the suction nozzle assembly 2, thereby improving work efficiency. In addition, since the present application sets the heater 22 on the side of the mounting surface 111 away from the suction nozzle, and contacts the adsorption end of the adsorption part 24, it can heat the adsorption end more directly, thereby improving the eutectic effect, and will not transfer heat directly to the main component 1. During this period, the base 21 of the suction nozzle assembly 2 will also buffer the heat dissipation, reducing the impact on the service life of the main component 1.
[0040] like Figure 3-Figure 5 As shown, in order to facilitate the positioning of the base 21 relative to the mounting seat 11 and the docking positioning of the first power-on end 121 and the first conductive end 2311, the mounting surface 111 has a first mounting hole 1111, and the side of the base 21 facing the mounting surface 111 has a protrusion 211, the protrusion 211 is arranged corresponding to the first mounting hole 1111, and the protrusion 211 is adapted to the first mounting hole 1111. As the base 21 is installed on the mounting surface 111, the protrusion 211 can be inserted into the first mounting hole 1111. The positioning of the base 21 relative to the mounting seat 11 is achieved through the cooperation of the protrusion 211 and the first mounting hole 1111, and the docking of the first power-on end 121 and the first conductive end 2311 can be achieved.
[0041] like Figure 3-Figure 5As shown, in order to achieve the connection of the adsorption part 24, the main body component 1 also includes a suction part 13, the suction part 13 is arranged in the first mounting hole 1111, and the protrusion 211 has a second mounting hole 2111 on the side facing the mounting surface 111, and the second mounting hole 2111 passes through the mounting seat 11, and the adsorption part 24 is arranged in the second mounting hole 2111. As the base 21 is installed on the mounting surface 111, the protrusion 211 can be inserted into the first mounting hole 1111 to connect the adsorption part 24 with the suction part 13. By setting the adsorption part 24 in the first mounting hole 1111 and the suction part 13 in the second mounting hole 2111, the correspondence between the adsorption part 24 and the suction part 13 can be achieved by utilizing the cooperation of the protrusion 211 and the first mounting hole 1111. Such a setting not only achieves the connection of the adsorption part 24, but also reduces the setting of the corresponding structures for the suction part 13 and the adsorption part 24, making the structure simpler.
[0042] like Figure 8 and Figure 9 As shown, in order to facilitate the connection between the adsorption part 24 and the suction part 13, the suction nozzle assembly 2 also includes an elastic part 25, the inner peripheral side wall of the second mounting hole 2111 has an inwardly extending ridge 2112, the outer peripheral side wall of the adsorption part 24 has a flange 241, the elastic part 25 is arranged on the side of the ridge 2112 facing the mounting surface 111, and the flange 241 of the adsorption part 24 overlaps the side of the elastic part 25 facing the mounting surface 111. As the base 21 is installed on the mounting surface 111, the adsorption part 24 can contact the suction part 13, and then the flange 241 and the ridge 2112 squeeze the elastic part 25. By setting the elastic part 25, a buffer is provided for the contact between the adsorption part 24 and the suction part 13 to avoid damage to the adsorption part 24 and the suction part 13 during docking.
[0043] like Figure 2-Figure 5 As shown, in order to facilitate the positioning of the base 21 relative to the mounting seat 11 and the docking of the first power-on end 121 and the first conductive end 2311, the mounting surface 111 is provided with a limiting portion 112, which extends along the outer peripheral side wall of the mounting seat 11 in a direction away from the mounting surface 111. The limiting portion 112 and the mounting surface 111 are enclosed to form a limiting groove 113. The inner peripheral side surface of the limiting portion 112 has a card groove 1121, and the outer peripheral side surface of the base 21 is provided with a card groove 1121. A clamping strip 215 is also provided, and the shapes of the clamping strip 215 and the clamping slot 1121 are adapted to each other. As the clamping strip 215 docks with the clamping slot 1121, the base 21 can slide along the limiting groove 113 until it is in contact with the mounting surface 111. The positioning of the base 21 relative to the mounting seat 11 is achieved through the cooperation between the limiting groove 113 and the base 21 and the cooperation between the clamping strip 215 and the clamping slot 1121, and the docking of the first power-on end 121 and the first conductive end 2311 can be achieved.
[0044] like Figure 2-Figure 5As shown, the protrusion 211 is cylindrical, the base 21 is truncated cone, and the side with a larger diameter is arranged toward the side of the mounting surface 111, the limiting groove 113 and the base 21 are adapted to each other, and the first mounting hole 1111 is adapted to the protrusion 211, that is, the axial direction of the suction nozzle assembly 2 is limited by the limiting groove 113 and the first mounting hole 1111, and the circumferential direction of the suction nozzle assembly 2 is limited by the cooperation of the clamping strip 215 and the clamping groove 1121, thereby ensuring the docking of the first conductive member 23 and the first conductive member 12.
[0045] like Figure 4 、 Figure 10 and Figure 11 As shown, in order to improve the heat dissipation capacity of the base 21, the interior of the base 21 is hollow, and the side of the base 21 facing away from the mounting surface 111 is open. The heater 22 is installed on the side of the base 21 facing away from the mounting surface 111, and together with the base 21, a cavity is formed. The outer peripheral side of the base 21 has a plurality of hollow holes 212. The first conductive member 23 is provided on the side of the base 21 facing the mounting surface 111, and extends through the cavity to the heater 22 to be electrically connected to the heater 22. The adsorption member 24 is provided on the side of the base 21 facing the mounting surface 111, and extends through the cavity to the heater 22 to pass through the heater 22. The present application sets the interior of the base 21 to a hollow state, and opens a plurality of hollow holes 212 on the outer peripheral side of the base 21 to dissipate heat to the first conductive member 23 and the heater 22, thereby reducing the heat transferred to the main component 1.
[0046] Optionally, in order to improve heat dissipation capability and reduce structural deformation, the base 21 is made of ceramic material.
[0047] like Figure 2-Figure 5 As shown, in order to facilitate the disassembly and assembly of the main assembly 1 and the nozzle assembly 2, the connecting assembly 3 includes a magnetic component 31 and a magnetic component 32. The magnetic component 31 is arranged on the mounting surface 111, and the magnetic component 32 is arranged on the side of the base 21 facing the mounting surface 111.
[0048] like Figure 3 、 Figure 4 、 Figure 8 、 Figure 10 and Figure 11As shown, in order to ensure the stability of magnetic attraction, the connecting component 3 includes a plurality of magnetic members 31, and the plurality of magnetic members 31 are arranged at intervals along the circumference of the mounting surface 111. The magnetic member 32 is annular and corresponds to the plurality of magnetic members 31. The side of the base 21 facing the mounting surface 111 has a mounting groove 213, and the magnetic member 32 is arranged in the mounting groove 213. The side of the magnetic member 32 facing the mounting surface 111 has a third mounting hole 321, and the base 21 has a fourth mounting hole 21 at a position corresponding to the third mounting hole 321. 4. The first conductive member 23 passes through the third mounting hole 321 and the fourth mounting hole 214 in sequence to the interior of the base 21, and then passes through the interior of the base 21 to connect with the heater 22. A gap is left between the third mounting hole 321 and the first conductive end 2311. The annular magnetic member 32 and the plurality of magnetic attracting members 31 are provided to ensure uniformity and magnitude of the magnetic force. The gap between the third mounting hole 321 and the first conductive end 2311 prevents the magnetic member 32 from communicating with the first conductive end 2311 and causing a short circuit.
[0049] like Figure 5 、 Figure 9 and Figure 10 As shown, the side of the magnetic part 32 facing the mounting surface 111 is received in the mounting groove 213. When the base 21 is installed on the mounting surface 111 through the cooperation of the magnetic part 32 and the magnetic attraction part 31, the side of the base 21 facing the mounting surface 111 abuts against the mounting surface 111, and a space is left between the magnetic part 32 and the magnetic attraction part 31 provided on the mounting surface 111. In this application, the magnetic part 32 is arranged to be received in the mounting groove 213, and the mounting groove 213 and the mounting surface 111 jointly form a closed space to avoid the external environment from affecting the contact electrical connection between the first conductive end 2311 and the first power-on end 121 during the use of the heater 22. The space left between the magnetic part 32 and the magnetic attraction part 31 is used for heat dissipation of the electrical connection between the first conductive end 2311 and the first power-on end 121.
[0050] In some embodiments, the elastic member 25 is an elastic sealing ring, which can achieve a buffering effect while preventing external air from affecting the contact and electrical connection between the first conductive end 2311 and the first power supply end 121 through the space between the adsorption member 24 and the second mounting hole 2111.

The nozzle component 2 includes a plurality of first conductive parts 23, and a plurality of first conductive ends 2311 are respectively arranged in one-to-one correspondence with the plurality of first power-carrying ends 121. By arranging a plurality of first power-carrying parts 12 and a plurality of first conductive parts 23, the input power to the heater 22 is increased, and the heater 22 is quickly heated up. In addition, the method of supplying power together by the plurality of first power-carrying parts 12 and the plurality of first conductive parts 23 can also reduce the heat generated during the transmission of the current compared to the method of supplying power by a wiring harness.
[0052] like Figure 3 、 Figure 4 and Figure 11 As shown, in order to facilitate real-time detection and control of the temperature of the heater 22, the nozzle assembly 2 further includes a sensor 26 and a second conductive member 27.

The second conductive member 27 has a second conductive end 271, and the second conductive end 271 is arranged on the side of the base 21 facing the mounting surface 111. As the base 21 is installed on the mounting surface 111, the second conductive end 271 can be electrically connected to the second power-on end 141. The temperature of the heater 22 is detected by setting the sensor 26, and through the setting of the second power-on member 14 and the second conductive member 27, the sensor 26 can also be integrated on the suction nozzle assembly 2 in a contact conductive manner, thereby avoiding affecting the disassembly and assembly of the suction nozzle assembly 2.

[0054] like Figure 8 and Figure 11 As shown, for ease of use, the first conductive member 23 includes a conductive contact 231 and a wire 232. The conductive contact 231 is arranged on the side of the base 21 facing the mounting seat 11, and the end of the conductive contact 231 facing the mounting surface 111 is the first conductive end 2311. The wire 232 is arranged inside the base 21, and one end is electrically connected to the conductive contact 231, and the other end is electrically connected to the heater 22.
[0055] like Figure 7 、 Figure 10 、 Figure 11 and Figure 12 As shown, in order to facilitate assembly, the conductive contact 231 and the wire 232 are detachably connected. In combination with the above technical solution, the nozzle assembly 2 further includes a fixing plate 28, which is located inside the base 21. The fixing plate 28 has a plurality of fifth mounting holes 281, and the plurality of fifth mounting holes 281 are arranged in a one-to-one correspondence with the plurality of fourth mounting holes 214. The inner peripheral side wall of the fourth mounting hole 214 has an abutment portion 2141 extending inwardly, and the outer peripheral side wall of the conductive contact 231 has an abutment block 2312 extending outwardly. The conductive contact 231 is sequentially inserted into the third mounting hole 321, the fourth mounting hole 321, and the fourth mounting hole 214. The fourth mounting hole 214 and the fifth mounting hole 281, and the abutment block 2312 can be clamped between the abutment portion 2141 and the fixed plate 28, and the end of the conductive contact 231 facing away from the mounting surface 111 can pass through the fifth mounting hole 281 from the fixed plate 28 and be connected to the wire 232. When assembling the suction nozzle assembly 2, the conductive contact 231 can be first installed on the base 21 through the fixed plate 28, and then the wire 232 and the conductive contact 231 can be connected. Finally, the adsorption component 24 and the heater 22 are installed on the base 21, and the wire 232 is connected to the heater 22.
[0056] like Figure 4 、 Figure 5 and Figure 13 As shown, in order to improve the heating effect of the chip, the suction nozzle assembly 2 also includes a heat conductor 29, and one side of the heat conductor 29 has an adsorption hole 291. The heat conductor 29 is sleeved on the adsorption end through the adsorption hole 291, and the adsorption hole 291 runs through the side of the heat conductor 29 facing away from the heater 22. The side of the heat conductor 29 facing the heater 22 is in contact with the heater 22. The side of the heat conductor 29 facing away from the heater 22 is a heating surface 292, and the heating surface 292 is used to heat the chip. The heat of the heater 22 is transferred to the chip by setting the heat conductor 29, and since the specifications of the heat conductor 29 can be adjusted according to the size of the chip, the heat transferred by the heat conductor 29 can be more evenly transferred to the chip, avoiding quality problems of the chip caused by regional temperature differences.
[0057] To achieve the same purpose, a die bonding machine according to an embodiment of the present invention includes the above-mentioned mounting mechanism.
[0058] In summary, the embodiment of the present invention provides a mounting mechanism and a die bonding machine, which enables the heater 22 to be electrically connected in a contact conductive manner by setting a first conductive member 23 and a first energizing member 12. Specifically, after the nozzle assembly 2 is installed to the main assembly 1, the first conductive end 2311 of the first conductive member 23 can contact the first energizing end 121 of the first energizing member 12, and the first energizing member 12 transmits current to the heater 22 through the first conductive member 23 to energize the heater 22. On this basis, the present application integrates the heater 22 on the base 21 of the nozzle assembly 2, so that the present application can be disassembled and assembled between the nozzle assembly 2 and the main assembly 1 through the connecting assembly 3. The heater 22 and the base 21 can be disassembled and assembled together, and the setting of the heater 22 will not affect the disassembly and assembly of the base 21, so that the present application can realize the heating of the nozzle assembly 2 and conveniently complete the replacement of the nozzle assembly 2, thereby improving work efficiency. In addition, since the present application sets the heater 22 on the side of the mounting surface 111 away from the nozzle and contacts the adsorption end of the adsorption part 24, it can heat the adsorption end more directly, improve the eutectic effect, and will not transfer heat directly to the main component 1. During this period, the base 21 of the nozzle assembly 2 will also buffer the heat dissipation, reducing the impact on the service life of the main component 1.
[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
