Description

Technical Field

[0001] The present invention relates to the field of chip packaging, and in particular to a 3D packaging structure and packaging process for chips. Background Art

[0002] Chip packaging is the last step of integrated circuits. It is the process of assembling integrated circuits into final chip products. Specifically, it is to place the integrated circuit bare die produced by the foundry on a supporting substrate, lead out the pins, and then fix the package into a whole. This process includes steps such as placement, fixation, sealing, and lead-in. Packaging not only plays the role of installing, fixing, sealing, protecting chips and enhancing electrical and thermal performance, but also connects the contacts on the chip to the pins of the package shell with wires. These pins are connected to other devices through wires on the printed circuit board, thereby realizing the connection between the internal chip and the external circuit.

[0003] After searching, the patent application document with the prior art publication number CN115101492A discloses a 3D chip packaging heat dissipation structure, which relates to the field of 3D chip technology. It includes: a circuit board, the top of which is provided with a mounting groove; a stacked chip, the mounting groove of the circuit board is provided with a stacked chip; a cooling component, the cooling component is arranged on the top and inside of the stacked chip; a water leakage detection component, the water leakage detection is arranged between the cooling component and the stacked chip. The present invention can, through the arrangement of the water leakage detection component, protect water from entering the inside of the chip when the structure leaks. Since the microchannel tube is an integrated structure, the possibility of water leakage is the greatest at the connection between the microchannel tube and the water distribution pipe or the connection between the microchannel tube and the water collection pipe. A cable-type water immersion sensor is arranged here. When a water leakage occurs, an alarm is immediately sounded to remind the user to ensure that water does not enter the inside of the chip, thereby ensuring the service life of the chip.

[0004] Compared with the above-mentioned documents, although the above-mentioned documents realize that by setting a cable-type water immersion sensor, an alarm will be immediately sounded to remind the user when a water leak occurs, so as to ensure that water will not enter the chip, thereby ensuring the service life of the chip. However, when the chip is packaged, resistance will be generated when the current flows inside the chip, thereby generating heat, and the transistor inside the chip will also briefly generate high heat when switching states. Excessive accumulation of heat can easily cause the chip to overheat or even damage it. In the above-mentioned documents, micro-ducts are set around the chip package and the effect of blowing is used to increase the air circulation around the chip when it is packaged, and the heat generated when the chip is packaged is taken away accordingly. When the chip is packaged, more heat accumulates, which will make the temperature of the outer wall of the chip higher. The above-mentioned method only blows away the heat, and cannot cool the outer wall of the chip, which correspondingly reduces the use effect of the chip, thereby reducing the work efficiency of the staff in packaging and using the chip. For this reason, a 3D packaging structure and packaging process for chips are proposed. Summary of the invention

Under normal conditions, the movable screen plate, based on the action of the alcohol liquid resistance, makes it impossible for the sliding rod to drive the limit slide plate and the push rod to squeeze the alarm switch to give an alarm.

[0024] When the alcohol inside the rotating block is consumed, the movable mesh plate loses the resistance of the alcohol liquid, and the push rod can press the alarm switch to alarm, thereby reminding the staff that the alcohol inside the rotating block is consumed, making it convenient for the staff to add alcohol, thereby improving the staff's efficiency in using the air blowing and cooling mechanism.

[0041] It should be noted that: the staff packages the stacked chips 5, which is a prior art, and its working principle will not be described in detail;

[0042] Embodiment 2

[0043] like Figure 3 , Figure 6 As shown, in the further detailed description of the above embodiment, the air blowing cooling mechanism is used to cool the stacked chips 5 located inside the support box 3 during packaging. The air blowing cooling mechanism is located at the bottom of the sliding sealing mechanism and is located inside the support box 3. The air blowing cooling mechanism includes a servo motor 6 installed at the bottom of the cover plate 4. The output end of the servo motor 6 is fixedly connected to a rotating shaft 601, and the outer wall of the rotating shaft 601 is fixedly connected to a rotating block 602. The outer wall of the rotating block 602 is fixedly connected to a plurality of fan blade sleeves 603. The interior of the fan blade sleeve 603 is fixedly connected to a reset spring 604. The reset spring 604 One end away from the fan blade sleeve 603 is connected to a limit plate 605, and one end of the limit plate 605 away from the return spring 604 is connected to a fan blade 607, and one end of the fan blade 607 away from the limit plate 605 slides and extends to the outside of the fan blade sleeve 603, the outer wall of the rotating block 602 is connected to a plurality of inlet hoses 606, and the plurality of inlet hoses 606 extend to the inside of a plurality of fan blade sleeves 603 respectively, and one end of the fan blade 607 away from the limit plate 605 is fixedly connected to a rotating magnetic block 608, and the inner wall of the support box 3 is fixedly connected to a plurality of mounting magnetic blocks 609 that attract each other with opposite poles corresponding to the rotating magnetic block 608;

[0044] The present invention is further specifically described in detail that the interior of the rotating shaft 601 and the rotating block 602 are hollow, and the interior of the rotating shaft 601 and the rotating block 602 are connected, and a feed hole is provided on the top of the outer wall of the rotating shaft 601, and one end of the feed hose 606 away from the rotating block 602 is connected to the fan blade 607, and the interior of the fan blade 607 is hollow, and the fan blade 607 is connected to the interior of the rotating block 602 through the feed hose 606, and a plurality of spray holes are provided on the outer wall of the fan blade 607, and the outer wall of the limit plate 605 and the inner wall of the fan blade sleeve 603 are slidably fitted;

[0045] Through the setting of the above technical solution, when it is used specifically: after the cover plate 4 and the support box 3 are closed and the stacked chip 5 is packaged, the servo motor 6 is turned on to make the servo motor 6 work. When the servo motor 6 works, it drives the rotating shaft 601 to rotate. When the rotating shaft 601 rotates, it drives the multiple fan blade sleeves 603 and multiple fan blades 607 on its outer wall to rotate. Correspondingly, according to the effect of the fan blade sleeves 603 and the fan blades 607 rotating and blowing, the stacked chip 5 can be rotated and blown, so that the heat generated by the stacked chip 5 during packaging can be blown away;

[0046] When the cover plate 4 drives the air blowing and cooling mechanism to be stored in the interior of the support box 3, the rotating magnetic block 608 corresponds to the installing magnetic block 609, and when the fan blade 607 drives the rotating magnetic block 608 to rotate, when the rotating magnetic block 608 rotates to the position of the installing magnetic block 609, according to the effect of the attraction between the opposite poles, the rotating magnetic block 608 drives the fan blade 607 to slide to the outside of the fan blade sleeve 603, and then the multiple spray holes on the outer wall extend to the outside of the fan blade sleeve 603, and the alcohol inside the fan blade 607 is sprayed out accordingly. In addition, the fan blade 607 rotates and blows air, so that the alcohol can be atomized and sprayed into the interior of the support box 3, and the atomized alcohol can be sprayed to the outside of the stacked chips 5, which is corresponding to the stacked chips. The chip 5 is cooled and lowered, and when the rotating magnetic block 608 is separated from the mounting magnetic block 609, the spray hole can be stored inside the fan blade sleeve 603, and the fan blade 607 can reciprocate to drive the spray hole to extend to the outside of the fan blade sleeve 603, so that the alcohol is sprayed reciprocally, thereby reducing the alcohol consumption rate.

[0047] It should be noted that the initial rotation centrifugal force of the fan blade 607 cannot extend the spray hole to the outside of the fan blade sleeve 603. When the rotating fan blade 607 drives the rotating magnetic block 608 to correspond to the mounting magnetic block 609, the spray hole can be driven to extend to the outside of the fan blade sleeve 603.

[0048] Embodiment 3

[0049] like Figure 6 , Figure 7 As shown, in the further detailed description of the above embodiment, the mixing alarm mechanism is used to mix the alcohol inside the blowing and cooling mechanism, and to alarm after its use.

A telescopic rod 703 is fixedly connected to the side of the limiting slide plate 701 away from the sliding rod 702, and one end of the telescopic rod 703 slides and extends to the outside of the sliding sleeve 7. A mobile mesh plate 704 is fixedly connected to one end of the telescopic rod 703 away from the limiting slide plate 701. A top rod 705 is fixedly connected to the side of the limiting slide plate 701 located on the sliding rod 702. An alarm switch 706 is provided on the inner wall of the sliding sleeve 7.

[0050] The present invention is further described in detail, the outer wall of the limit slide plate 701 and the inner wall of the sliding sleeve 7 are slidingly fitted, the top rod 705 and the alarm switch 706 are correspondingly extruded, the alarm switch 706 is a kind of touch switch, the movable mesh plate 704 is located inside the rotating block 602, and a plurality of flow holes are opened on the movable mesh plate 704;

[0051] Through the arrangement of the above technical solution, in specific use: when the fan blade 607 drives the spray hole to slide back and forth, it can drive the sliding rod 702 and the limiting slide plate 701 to slide back and forth, and correspondingly drive the movable mesh plate 704 to slide back and forth inside the rotating block 602. The reciprocating movement of the movable mesh plate 704 can be used to move and stir the alcohol inside the rotating block 602. In addition, the plurality of flow holes on the movable mesh plate 704 increase the flow and stirring effect of the alcohol inside the rotating block 602, and correspondingly increase the volatilization effect of the alcohol spraying, thereby improving the alcohol The volatilization cooling effect of the spraying, under normal conditions, the movable mesh plate 704, based on the effect of the alcohol liquid resistance, makes the sliding rod 702 unable to drive the limit slide plate 701 and the top rod 705 to squeeze the alarm switch 706 to alarm, and when the alcohol inside the rotating block 602 is consumed, the movable mesh plate 704 loses the resistance effect of the alcohol liquid, and the top rod 705 can press the alarm switch 706 to alarm, which reminds the staff that the alcohol inside the rotating block 602 is consumed, which is convenient for the staff to add alcohol, thereby improving the staff's use efficiency of this air blowing and cooling mechanism;
