When eutectic welding is performed on the heating platform 41, the hot nitrogen can ensure the uniformity of heating of the product and the chip, and can also prevent oxidation, thereby improving the eutectic welding effect of the product and the chip.

[0039] Reference Figure 2 and Figure 3 A long charging hole 16 is provided on the side wall of the eutectic table 1, and the length direction of the long charging hole 16 is arranged along the spacing direction of the first station 11 and the second station 12. Two product insertion grooves 411 are provided on the side wall of the heating table 41, and the two product insertion grooves 411 are respectively located at the first station 11 and the second station 12. The product insertion groove 411 penetrates the heating table 41 along its own length direction, and one end of the product insertion groove 411 along its own length direction is arranged opposite to the long charging hole 16, and the two product insertion grooves 411 are connected to the long charging hole 16.

This makes it possible to observe the eutectic welding of the product and the chip at the first station 11 through the first hole 151, and the eutectic welding of the product and the chip at the second station 12 through the second hole 152.

[0041] Reference Figure 2 and Figure 3 The eutectic table 1 is also provided with two positioning components 5 , which are respectively located at the first station 11 and the second station 12 .

[0042] Reference Figure 3 and Figure 4 The positioning assembly 5 includes a positioning column 51 , which is located on a side of the heating platform 41 facing the charging slot 16 , and is located between the heating platform 41 and the inner side wall of the heating tank 14 .

[0043] Reference Figure 3 The positioning column 51 is arranged in the vertical direction, and the fixing seat 2 is provided with an installation cavity 21. The upper end of the positioning column 51 is located between the outer wall of the heating platform 41 and the inner wall of the heating tank 14, and the lower end of the positioning column 51 is located in the installation cavity 21. The positioning column 51 is slidably connected with the outer wall of the heating platform 41, the inner wall of the heating tank 14, and the inner wall of the installation cavity 21 in the vertical direction. The positioning column 51 is located directly below the corresponding product insertion groove 411 in the vertical direction.

[0044] By setting the positioning column 51, after the product is loaded into the corresponding product insertion slot 411, when the positioning column 51 moves vertically upward, the upper end of the positioning column 51 will abut against the corresponding product, thereby achieving the fixation of the product.

[0045] Reference Figure 4 A positioning groove 511 is provided at the upper end of the positioning column 51. When the positioning column 51 rises and contacts the product corresponding to the first station 11 or the second station 12, the product is plugged into the corresponding positioning groove 511. Therefore, the opening of the positioning groove 511 can achieve the positioning of the product, further improve the stability of the product fixation and the accuracy of positioning, and thus improve the accuracy of the eutectic welding of the product and the chip.

[0046] Reference Figure 1 and Figure 3 , the positioning assembly 5 also includes a lifting drive 52, which is located in the installation cavity 21. The lifting drive 52 includes a connecting column 521, a lifting block 522, a cam 523 and a reset spring 525.

The reset spring 525 is arranged in the vertical direction, and one end of the reset spring 525 is connected to the lifting block 522, and the other end is connected to the inner side wall of the installation cavity 21.

[0047] When the driving motor 524 drives the cam 523 to rotate, due to the setting of the return spring 525, the upper side of the lifting block 522 always contacts the outer side wall of the cam 523, and then the lifting block 522 can reciprocate in the vertical direction through the rotation of the cam 523, and then the connecting column 521 can reciprocate in the vertical direction, and at this time, the connecting column 521 can drive the corresponding positioning column 51 to rise and fall. This satisfies the function of the lifting drive member 52.

[0048] Reference Figure 3 The lifting block 522 is provided with a wear-resistant steel sheet 526 on one side facing the cam 523. The wear-resistant steel sheet 526 is connected to the lifting block 522 along its thickness direction on one side and contacts the cam 523 on the other side. The provision of the wear-resistant steel sheet 526 can reduce the wear between the cam 523 and the lifting block 522, thereby increasing the service life of the lifting drive member 52.

One end of the air duct 181 is connected to the gas storage member 18, and the other end is connected to the eutectic stage 1, and the air duct 181 is connected to the eutectic chamber 17. This allows cold nitrogen to be injected into the eutectic chamber 17, and after the eutectic welding of the products and chips on the first station 11 and the second station 12 is completed, the products and chips can be quickly cooled down. At the same time, due to the use of nitrogen, a nitrogen atmosphere can be guaranteed, thereby making the tin melting effect better during the eutectic welding process.

[0050] Reference Figure 2 and Figure 3 A wind knife 19 is also provided on one side of the eutectic table 1. A plurality of wind holes 191 are provided on the side of the wind knife 19 facing the eutectic table 1. The plurality of wind holes 191 are all provided toward the upper side of the transparent plate 15. An auxiliary pipe 192 is provided between the wind knife 19 and the gas storage member 18. One end of the auxiliary pipe 192 is connected to the gas storage member 18, and the other end is connected to the wind knife 19. The plurality of wind holes 191 are all connected to the auxiliary pipe 192. This allows cold nitrogen to be blown toward the transparent plate 15, thereby reducing the temperature difference between the inside and outside of the transparent plate 15 and reducing the possibility of fogging of the transparent plate 15.

The vacuum adsorption hole 412 is located at the third station 13, and the vacuum adsorption hole 412 and the third hole 153 are arranged vertically opposite each other. A suction piece 44 is provided on the outside of the eutectic table 1, and the suction piece 44 is connected to the heating table 41 through a pipeline. When the chip is transported to the heating table 41 through the third hole 153, the air in the heating cavity is extracted by the suction piece 44, and a negative pressure can be formed at the vacuum adsorption hole 412, so that the chip can be adsorbed to achieve chip fixation, which can realize eutectic welding of double-layer chips.

[0054] In this embodiment, the first station 11 and the second station 12 adopt the following eutectic welding process: a plurality of chips are arranged on the product, so that the plurality of chips are eutectically welded to the product to obtain a finished product.
