Description

Technical Field

[0001] The utility model relates to the field of chip reuse, and more specifically, to a chip reuse reactor. Background Art

[0002] Integrated circuit chips will be provided with an epoxy resin encapsulation structure on their exterior. However, during the chip production process, there are often cases where the wire bonding is poor but the chip performance is good. In such cases, the epoxy resin encapsulation of the chip needs to be removed, that is, the chip is separated, so as to test and repair the chip performance.

[0003] The current method is to put multiple chips into a large reactor filled with a solvent solution, and then heat the solvent solution through a heating device. After the chips and the solvent solution are heated and react, the encapsulation of the chips is softened so that the chips can be taken out of the encapsulation. However, at this time, all the chips will be scattered in the solvent solution in this reactor, and tools such as a filter net spoon need to be used to fish out the scattered chips in the reactor one by one, which is very inconvenient. And after different types of chips are put into the reactor together for heating reaction, the different types of chips are mixed together. After all the chips are fished out of the reuse reactor, classification is still required, which is very troublesome. Summary of the Utility Model

[0004] In view of the above-mentioned defects of the prior art, a chip reuse reactor is provided.

The cover plate is detachably connected to the bottom plate, and after connection, the cover plate abuts against the upper end of the explosion-proof sleeve.

[0006] Preferably, the jig is a filter net cylinder and the top is open, and a plurality of the jigs are stacked from bottom to top in the reactor lining.

[0010] Preferably, the limiting portion is located on the upper surface of the bottom plate, the limiting portion is a groove body with an annular structure, and the bottom end of the explosion-proof sleeve is inserted into the limiting portion in a matching manner.

[0011] Preferably, an annular cover plate groove is provided on the lower surface of the cover plate, and the top end of the explosion-proof sleeve is inserted into the cover plate groove in a matching manner.

[0021] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments.

In addition, the directional terms mentioned in the present utility model, for example, "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present utility model, rather than indicating or implying the directions that the present utility model must have. Therefore, it cannot be understood as a limitation to the present utility model.

[0022] As shown in the embodiment of the present utility model Figures 1 to 4 A chip reuse reactor, including a reactor body and a reactor lining 6. The reactor body includes a bottom plate 1, an explosion-proof sleeve 2, and a cover plate 4. The explosion-proof sleeve 2 is arranged at the center position of the upper surface of the bottom plate 1. A limiting part 11 for limiting the explosion-proof sleeve 2 is arranged on the bottom plate 1. The explosion-proof sleeve 2 is of a circular tube structure and is arranged vertically. The reactor lining 6 is arranged in the explosion-proof sleeve 2 and is located on the upper surface of the bottom plate 2. The reactor lining 6 is a cylindrical reactor lining 6. The shape and size of the outer surface of the reactor lining 6 are adapted to the shape and size of the inner hole of the explosion-proof sleeve 6. A plurality of jigs 7 for loading chips are arranged in the reactor lining 6. One or more water inlet and outlet holes are arranged on the jig 7. The cover plate 4 is detachably connected to the bottom plate 1, and after connection, the cover plate 4 abuts against the upper end of the explosion-proof sleeve 2.

[0023] Place the chips into multiple fixtures 7, then place the multiple fixtures 7 into the inner lining 6 of the reactor. Add a solvent solution to the inner lining 6 of the reactor. The Chinese invention patent discloses a method for non-destructive chip separation, packaging testing and reuse of electronic devices (Application No.: 202210552667.7). The solvent solution uses the mixed solvent formulation solution disclosed therein. The explosion-proof sleeve 2 is arranged on the upper surface of the bottom plate 1 and is limited by the limiting part 11 to prevent the explosion-proof sleeve 2 from moving. Subsequently, place the inner lining 6 of the reactor into the explosion-proof sleeve 2, then cover the cover plate 4 on the upper end of the explosion-proof sleeve 2, and then connect the cover plate 4 to the bottom plate 1 so that the explosion-proof sleeve 2 is clamped and fixed between the cover plate 4 and the bottom plate 1. Finally, place the reactor installed with chips into a constant temperature oven for heating. After the heating reaction, the chips in the inner lining 6 of the reactor can be quickly taken out by taking out the fixture 7. And when different types of chips need to be placed simultaneously for heating reaction, only need to classify and place the chips into multiple corresponding fixtures 7, which makes different types of chips not mix together and there is no need to classify the chips again, which is very convenient.

[0024] Further improvement, as Figure 1 and Figure 2 shown in, the fixture 7 is a filter mesh cylinder and the top is open. Preferably, there are two fixtures 7, and the two fixtures 7 are stacked from bottom to top in the inner lining 6 of the reactor. The shape and size of the outer surface of the fixture 7 are adapted to the shape and size of the inner hole of the inner lining 6 of the reactor, that is, the inner hole of the inner lining 6 of the reactor is a cylindrical hollow structure, and the fixture 7 is cylindrical. When the fixture 7 is taken out, the solvent solution will leak out from the filter mesh structure of the fixture 7, and the fixture 7 will not bring out the solvent solution.

[0025] Further improvement, as Figure 2 and Figure 3 shown in, there are multiple threaded holes 10 distributed in a ring on the bottom plate 1. Preferably, there are six threaded holes 10. There are six through holes 40 on the cover plate 4 that are directly opposite to the threaded holes 10 one by one. The chip reuse reactor further includes six bolts 5, and the bolts 5 pass through the corresponding through holes 40 and are threadedly connected to the corresponding threaded holes 10.

[0026] Further improvement, as Figure 2 and Figure 4As shown in the figure, the limiting part 11 is located on the upper surface of the bottom plate 1. The limiting part 11 is a groove body with an annular structure. The limiting part 11 is a circular ring structure matching the explosion-proof sleeve 2. The bottom end of the explosion-proof sleeve 2 is inserted into the limiting part 11 in a matching manner. The lower surface of the cover plate 4 is provided with an annular cover plate groove 41, and the cover plate groove 41 is also a circular ring structure. The top end of the explosion-proof sleeve 2 is inserted into the cover plate groove 41 in a matching manner. The limiting part 11 limits and guides the explosion-proof sleeve 2, and the cover plate groove 41 positions the cover plate 4, facilitating the installation of the explosion-proof sleeve 2 and the cover plate 4.

[0027] For further improvement, as Figure 1 and Figure 2 shown in the figure, the reactor lining 6 includes a lining main body 60 and a lining cover 61. The lining main body 60 is arranged inside the explosion-proof sleeve 2, and the lining cover 61 covers the top end of the lining main body 60. A gasket 3 is arranged inside the explosion-proof sleeve 2. The upper surface of the gasket 3 abuts against the lower surface of the cover plate 4, and the lower surface of the gasket 3 abuts against the lining cover 61 of the reactor lining 6, that is, the lower surface of the gasket 3 abuts against the upper surface of the lining cover 61 of the reactor lining 6. The gasket 3 limits the reactor lining 6 in the up and down directions, preventing the lining cover 61 of the reactor lining 6 from being lifted by steam during the heating reaction, thereby preventing the high-temperature and high-pressure environment required for the reaction between the chip and the solvent solution from being unable to be maintained.

[0028] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
