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 bonding technology that fuses metal to metal. It uses various heating methods to melt the alloy layer between eutectic chips, eutectic chips and bases or lead frames, thereby forming a stable metal-to-metal molten bond. Compared with traditional bonding methods, metal-to-metal bonding improves bonding strength, reduces bonding impedance, and improves thermal conductivity.
[0003] At present, when performing a eutectic process, eutectic is usually achieved by substrate heating or nozzle assembly heating. When substrate heating is used, since the chips need to be eutectic 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 in 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.

[0039] Based on the above scheme, the present application sets a first conductive member 23 and a first energizing 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 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.

During this period, the base 21 of the suction nozzle assembly 2 will also buffer the heat dissipation, thereby 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-carrying 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.

[0041] like Figure 3-Figure 5As shown, in order to achieve the connectivity of the adsorption member 24, the main body component 1 also includes a suction member 13, and the suction member 13 is arranged in the first mounting hole 1111. 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 member 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 member 24 with the suction member 13. By setting the adsorption member 24 in the first mounting hole 1111 and the suction member 13 in the second mounting hole 2111, the correspondence between the adsorption member 24 and the suction member 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 connectivity of the adsorption member 24, but also reduces the setting of the corresponding structures for the suction member 13 and the adsorption member 24, making the structure simpler.
[0042] like Figure 8 and Fig. 9 As shown, in order to facilitate the connection between the adsorption member 24 and the suction member 13, the suction nozzle assembly 2 also includes an elastic member 25, the inner peripheral side wall of the second mounting hole 2111 has an inwardly extending convex edge 2112, the outer peripheral side wall of the adsorption member 24 has a flange 241, the elastic member 25 is arranged on the side of the convex edge 2112 facing the mounting surface 111, the flange 241 of the adsorption member 24 overlaps the side of the elastic member 25 facing the mounting surface 111, as the base 21 is installed on the mounting surface 111, the adsorption member 24 can contact with the suction member 13, and then the flange 241 and the convex edge 2112 squeeze the elastic member 25, and the elastic member 25 is provided to provide a buffer for the contact between the adsorption member 24 and the suction member 13, thereby avoiding damage to the adsorption member 24 and the suction member 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-carrying end 121 and the first conductive end 2311, the mounting surface 111 is provided with a limiting portion 112, the limiting portion 112 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 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 is docked 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 current-carrying member 12.
[0045] like Figure 4 , Fig.10 and Fig.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 outer peripheral side of the base 21 has a plurality of hollow holes 212. The first conductive member 23 is arranged 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 arranged 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.

The magnetic member 32 is annular and corresponds to the plurality of magnetic members 31.

The uniformity and magnitude of the magnetic force are ensured by arranging the annular magnetic member 32 and the plurality of magnetic attracting members 31, and the gap between the third mounting hole 321 and the first conductive end 2311 is used to prevent the magnetic member 32 and the first conductive end 2311 from being connected to cause a short circuit.
[0049] like Figure 5 , Fig. 9 and Fig.10 As shown, the side of the magnetic member 32 facing the mounting surface 111 is received in the mounting groove 213. When the base 21 is mounted on the mounting surface 111 through the cooperation of the magnetic member 32 and the magnetic attraction member 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 member 32 and the magnetic attraction member 31 provided on the mounting surface 111. In the present application, the magnetic member 32 is arranged to be received in the mounting groove 213, and a closed space is formed by the mounting groove 213 and the mounting surface 111 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, and the space left between the magnetic member 32 and the magnetic attraction member 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 prevent the external air from passing through the space between the adsorption member 24 and the second mounting hole 2111 and affecting the contact electrical connection between the first conductive end 2311 and the first power-on end 121 while achieving a buffering effect.

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 penetrated in the third mounting hole 321, the fourth mounting hole 214, and the conductive contact 231 is sequentially penetrated in the third mounting hole 321, the fourth mounting hole 214, and the conductive contact 231 is sequentially penetrated in the third mounting hole 321, the fourth mounting hole 214, and the conductive contact 231 is sequentially penetrated in the third mounting hole 321, the fourth mounting hole 214, and the conductive contact 231 is sequentially penetrated in the third mounting hole 321, the fourth mounting hole 214, and the conductive contact 231 is sequentially penetrated in the third mounting hole 321, the fifth ... 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 away from the mounting surface 111 can pass through the fifth mounting hole 281 from the fixed plate 28 to connect with 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 are connected.

[0056] like Figure 4 , Figure 5 and Fig.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 away from the heater 22, and 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 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, thereby avoiding quality problems of the chip caused by regional temperature differences.
[0057] In order to achieve the same purpose, a die bonding machine according to an embodiment of the present invention includes the mounting mechanism as described above.
[0058] In summary, the embodiment of the present invention provides a mounting mechanism and a die bonding machine, which enable 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 from 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 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 with the adsorption end of the adsorption member 24, it is possible to heat the adsorption end more directly, thereby improving the eutectic effect, and the heat will not be directly transferred to the main component 1. During this period, the base 21 of the suction nozzle assembly 2 will also buffer the heat dissipation, thereby 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.
