[0002] In the semiconductor packaging process, traditional packaging is still the main method. With the improvement of production efficiency and the reduction of costs, the carriers in the chip manufacturing process have gradually shifted from traditional round to square.

[0034] This embodiment provides a packaging fixture, such as Figure 1-Figure 3 As shown, the packaging fixture includes a carrying component 10 and a pressing component 20. The carrying component 10 includes a carrying part 11, an inflatable part 12 and a lifting part 13. The carrying part 11 is arranged on the support surface. The carrying part 11 is used to carry the workpiece 100. The inflatable part 12 is circumferentially arranged on the carrying part 11. The lifting part 13 is arranged on the inflatable part 12 so that the inflatable part 12 can drive the lifting part 13 to rise or fall in the vertical direction; the pressing component 20 includes a clamping part 21 and a pressing adsorption part 22. The clamping part 21 is arranged on the carrying component 10 so that the clamping part 21 and the carrying part 11 can jointly clamp the workpiece 100. The pressing adsorption part 22 is circumferentially arranged on the clamping part 21. The clamping part 21 and the carrying part 11 clamp the workpiece 100 so that the pressing adsorption part 22 can be adsorbed to the carrying component 10.

[0035] In the above structure, the inflatable member 12 is inflated to expand, and after expansion, the lifting member 13 can be lifted, and the lifting member 13 indirectly supports the carrier 11, so that the packaging fixture can be opened, and the workpiece 100 can be placed on the carrier 11; then the inflatable member 12 is deflated to shrink, and the lifting member 13 loses the support of the inflatable member 12 and gradually descends under the action of gravity, and the pressing member 21 also loses the support of the lifting member 13. At this time, the pressing member 21 will also gradually descend under the action of gravity until the pressing member 21 abuts against the workpiece 100. At this time, the pressing adsorption member 22 can be adsorbed onto the carrier assembly 10 to ensure the tightness of the connection between the two, so that the workpiece 100 can be firmly fixed between the carrier 11 and the pressing surface 211. This arrangement is simple in structure and easy to use. The packaging fixture can be opened and closed only by inflating or deflating the inflatable member 12, which is easy to operate and highly practical.

[0036] It should be noted that, in this embodiment, the inflatable member 12 is an airbag, which has a simple structure, is easy to use and install, and has high safety. Figure 1 As shown, the inflatable part 121 and the deflation part 122 of the inflatable member 12 are both arranged on the outer periphery of the carrier 11. This arrangement facilitates communication with an external air source, thereby facilitating use and avoiding interference with the workpiece 100 during the clamping process caused by being arranged on the inner periphery of the carrier 11.

[0037] To ensure the stability of the clamping process, Figure 1-Figure 4 As shown, the packaging fixture also includes a base 40, which is arranged on the support surface. The top surface of the base 40 is provided with a fixing part 41 along the circumference, and the fixing part 41 can fix the carrier 11. In order to further ensure that the carrier 11 does not shake, a plurality of fixing parts 41 are provided on the base 40, and the plurality of fixing parts 41 are evenly arranged along the outer circumference of the carrier 11. By providing a plurality of fixing parts 41, the carrier assembly 10 can be fixed on the base 40, thereby ensuring that the carrier 11 does not move when the inflatable part 12 expands or contracts, thereby ensuring stability. It should be noted here that, in this embodiment, the fixing part 41 is a cylinder, and the carrier 11 is fixed by the output end of the cylinder, thereby ensuring that the carrier 11 does not shake; the cylinder has a simple structure, low price, and is easy to use and install. In other embodiments, the fixing part 41 can also be a structure such as a telescopic motor, as long as it can fix the carrier 11, and no other restrictions are made in this embodiment.

[0038] In addition, if Figure 3 and Figure 4As shown, the bearing assembly 10 further includes a bearing adsorption member 14, which is circumferentially disposed on the bearing member 11. The pressing adsorption member 22 can be adsorbed onto the bearing adsorption member 14. This arrangement can further strengthen the clamping force of the pressing member 21 and the bearing member 11 on the workpiece 100, further ensuring a good clamping effect.

[0039] For ease of use, such as Figure 1 、 Figure 3 and Figure 4 As shown, the supporting member 11 and the pressing member 21 are both annular (square ring), and the supporting surface 111 of the supporting member 11 and the pressing surface 211 of the pressing member 21 are both provided with accommodating grooves along the circumferential direction. The inflatable member 12, the lifting member 13 and the supporting adsorption member 14 are correspondingly arranged in the accommodating grooves on the supporting member 11, and the pressed adsorption member 22 is correspondingly arranged in the accommodating grooves on the pressing member 21. The supporting surface 111 and the pressing surface 211 located on the inner side of the accommodating grooves can clamp the workpiece 100. The accommodating groove can accommodate the inflatable part 12, the lifting part 13, the bearing adsorption part 14 and the pressing adsorption part 22, thereby simplifying the structure on the bearing surface 111 and the pressing surface 211, thereby ensuring the simplicity and aesthetics of the overall structure; in addition, the bearing surface 111 and the pressing surface 211 located on the inner side of the accommodating groove are used to clamp the workpiece 100, which can avoid the lifting part 13 from interfering with the workpiece 100 when pushing the pressing part 21 to rise, thereby ensuring that the workpiece 100 will not be damaged, thereby ensuring a good use effect.

[0040] like Figure 3 and Figure 4 As shown, the top of the load-bearing adsorbent 14 is flush with the load-bearing surface 111, and the compression adsorbent 22 is flush with the pressing surface 211. This arrangement can prevent the load-bearing surface 111 from being unable to closely adhere to the pressing surface 211 when the load-bearing adsorbent 14 and the compression adsorbent 22 are adsorbed against each other, thereby resulting in a poor clamping effect. It can also avoid the problem that when the load-bearing surface 111 and the pressing surface 211 abut, the tops of the load-bearing adsorbent 14 and the compression adsorbent 22 are both located in the receiving groove, resulting in a poor adsorption effect and an unstable connection between the load-bearing component 11 and the pressing component 21, thereby achieving a good clamping effect.

[0041] like Figure 3 and Figure 4As shown, two supporting adsorption members 14 are disposed opposite each other within the receiving groove on the supporting member 11, forming a lifting gap 15 between the two supporting adsorption members 14. The lifting member 13 can rise or fall within the lifting gap 15, and the lifting end 131 of the lifting member 13 can extend out of the lifting gap 15 to allow the press-fit assembly 20 to be separated from the supporting assembly 10. This arrangement not only rationally utilizes the space within the receiving groove, but also prevents interference between the lifting member 13 and the supporting adsorption member 14 during the rising process. It should be noted here that, in this embodiment, the cross-section of the bearing adsorption member 14 is L-shaped, one end of which is connected to the bottom of the receiving groove and forms a whole with the bearing member 11. The other ends of the two bearing adsorption members 14 are arranged opposite to each other, and one side of the two side surfaces of the L-shape is arranged parallel to the side wall of the receiving groove, and the other side is arranged parallel to the bearing surface 111, so as to ensure that a lifting gap 15 can be formed between the two, so as to ensure that the lifting member 13 can move within the lifting gap 15, and the lifting end 131 can extend from the gap formed by the ends of the two bearing adsorption members 14, so as to lift or drop the pressing member 21, thereby facilitating the placement of the workpiece 100. In addition, separately processing multiple bearing adsorption members 14 with L-shaped cross-sections can reduce the processing difficulty and facilitate the installation of the bearing adsorption members 14 in the receiving groove.

[0042] It should be noted that in this embodiment, the cross-section of the press-fit adsorbent 22 is rectangular and is directly disposed within the rectangular receiving groove, resulting in a simple structure and easy installation. It should be further noted that both the load-bearing adsorbent 14 and the press-fit adsorbent 22 are magnets, which are simple in structure, inexpensive, and easy to produce and use.

[0043] Considering that the packaging fixture needs to clamp the workpiece 100 and immerse it in the plating solution, long-term immersion may cause the supporting adsorption member 14 and the pressing adsorption member 22 to fail. To solve this problem, Figure 3 and Figure 4 As shown, the carrier 11 and the pressing member 21 are both circumferentially provided with a sealing member 30. The sealing member 30 ensures that the plating solution cannot enter the accommodating tank, thereby ensuring that the carrier adsorption member 14 and the pressing adsorption member 22 can be used normally.

[0044] To ensure the sealing effect, Figure 3 and Figure 4 As shown, first retaining grooves are provided on both sides of the receiving groove along the upper edge of the carrier 11, and sealing members 30 are provided in each of the first retaining grooves on both sides. This arrangement ensures that both sides of the receiving groove are sealed, thereby further ensuring the sealing effect of the receiving groove. In addition, the provision of the first retaining grooves facilitates the installation of the sealing members 30 and ensures the sealing members 30 are fixed effectively.

[0045] In addition, if Figure 3 and Figure 4As shown, the pressing member 21 is provided with second limiting grooves 23 on both sides of the receiving groove, and a sealing member 30 is designed in the second limiting groove 23 located on the inner side of the receiving groove. When the pressing member 21 and the carrier 11 clamp the workpiece 100, the sealing member 30 located on the outer side of the receiving groove on the carrier 11 can be correspondingly snapped into the second limiting groove 23 located on the outer side of the receiving groove on the pressing member 21. In this arrangement, when clamping the workpiece 100, the workpiece 100 is located on the inner side of the receiving groove and abuts against the sealing member 30 on both the upper and lower sides, while the sealing member 30 is only provided in the first limiting groove on the outer side of the receiving groove. When clamping the workpiece 100, the portion of the sealing member 30 protruding from the first limiting groove can be snapped into the second limiting groove 23, thereby ensuring a good sealing effect on both the inner and outer sides of the receiving groove, thereby extending the service life of the magnet.

[0046] It should be noted here that, in this embodiment, the sealing member 30 is a sealing ring made of rubber or silicone material. The sealing ring has a simple structure, is easy to produce, has a low cost, and has a certain degree of flexibility, which can prevent the workpiece 100 from being damaged.

[0047] The following describes the use process of the packaging fixture in this embodiment with reference to the accompanying drawings:

[0048] First, the inflatable member 12 is inflated, and the volume of the inflatable member 12 gradually increases. The inflatable member 12 pushes the lifting member 13 to rise in the vertical direction, so that the lifting member 13 can lift the pressing member 21;

[0049] Next, place the workpiece 100 on the carrier 11;

[0050] Finally, the inflatable member 12 is deflated, the volume of the inflatable member 12 gradually decreases, the lifting member 13 descends in the vertical direction, and the pressing member 21 descends in the vertical direction. When the pressing member 21 abuts and is adsorbed to the supporting member 11, the supporting member 11 and the pressing member 21 clamp the workpiece 100.

[0051] In summary, in this embodiment, the packaging fixture has a simple structure, is easy to clamp, and has high operating efficiency.

[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
