Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of chip packaging, and specifically to a multi-chip stacked packaging structure. Background Art
[0002] Chip packaging can play a role in protecting the chip, which is equivalent to the shell of the chip. It can not only fix and seal the chip, but also enhance its electrothermal performance. The quality of the packaging technology directly affects the performance of the chip itself and the design and manufacturing of the printed circuit board connected to it. However, during the chip packaging process, when it is basically in a state of no external fixation or one-way simple fixation, it is prone to deviation during packaging, which may lead to deviation in the docking between the chip and the substrate, resulting in a decrease in the overall packaging quality of the chip.
[0003] Currently, usually, the substrate is placed in the positioning structure manually, and the substrate is clamped by the clamping plate. Since the substrate is placed manually, although the position of the substrate is between the clamping plates, the four corner positions of the rectangular substrate cannot be guaranteed, and the position of the substrate needs to be adjusted manually. If the substrate is directly clamped by the clamping plate, it may cause the clamping plate to squeeze the corner of the substrate, resulting in damage to the substrate due to force.

DETAILED DESCRIPTION
[0031] See also Figure 1-12, the present invention provides a technical solution: a multi-chip stacked packaging structure, including a main body 100. On one side inside the main body 100, a carrier plate 101 and a top plate 102 are fixedly connected. There are multiple top holes 103 on the top of the top plate 102. A carrier plate 104 is slidably connected to the top of the carrier plate 101. Limiting strips 201 are fixedly connected to both sides of the carrier plate 104 respectively. Limiting grooves 200 slidably connected to the limiting strips 201 are respectively opened on both sides inside the main body 100. Multiple placing grooves 202 corresponding to the top holes 103 are opened on the top of the carrier plate 104. A placing frame 203 is fixedly connected to the bottom of the placing groove 202. An alignment structure for adjusting the position of the substrate is provided inside the placing frame 203. The alignment structure can orient one side of the substrate towards the sliding direction of the carrier plate 104. A pressure increasing structure for increasing the frictional resistance between the substrate and the placing frame 203 is provided at the bottom of the carrier plate 104. A fixing structure for fixing the position of the substrate is provided on the placing frame 203. A top contact structure for moving the carrier plate 104 upwards is provided at the bottom of the carrier plate 101. The top contact structure can trigger the fixing structure when moving the carrier plate 104 upwards;
[0032] During operation, when staff need to package chips, the staff can slide the carrier plate 104 to the left to expose the placing frame on the carrier plate 104 to the outside, and put the substrates required for packaging the chips into the placing frame. After the staff have placed the substrates, the staff start the pressure increasing structure and reset the position of the carrier plate 104. The pressure increasing structure can increase the resistance between the substrate and the placing frame 203. During the process of sliding the carrier plate 104, the alignment structure works to adjust the positions of the substrates that are in a messy position inside the placing frame 203, so that one side of the substrate faces the sliding direction of the carrier plate 104. The pressure increasing structure increases the frictional force between the substrate and the placing frame 203, avoiding the problem that the substrate cannot move due to lack of force during the operation of the alignment structure. After orienting one side of the substrate towards the sliding direction of the carrier plate 104, it is possible to avoid the problem that the four corners of the substrate are damaged by the extrusion of the fixing structure when the fixing structure positions the substrate. After the carrier plate 104 is reset, the staff start the top contact structure, which can make the carrier plate 104 drive the placing frame 203 to move upwards so that the fixing structure abuts against the top plate 102, and the fixing structure is triggered to fix the position of the substrate, facilitating subsequent chip packaging; by providing multiple placing frames 203, when the staff package chips, they can position the positions of multiple substrates, improving the packaging efficiency. The fixing structure positions the substrate to the middle position of the placing frame 203 and can stably clamp the substrate, solving the problems that it is prone to deviation during traditional packaging and there are deviations in the docking between the chip and the placement points on the substrate. Before the fixing structure works, the provided alignment structure aligns the position of the substrate, thus avoiding the problem that the substrate is damaged by the fixing structure when the fixing structure fixes the substrate because the four corners of the substrate face the fixing structure when the substrate is placed.
[0033] As a further solution of the present invention, the alignment structure includes a plurality of rotating holes 204 opened on one side of the loading plate 104, the rotating holes 204 pass through the loading plate 104 and the storage frame 203, a rotating rod 205 is rotatably connected in the rotating holes 204, a plurality of first cavities 206 connected to the rotating holes 204 are opened in the storage frame 203, a connecting hole 207 connected to the first cavity 206 is opened on the inner bottom surface of the storage frame 203, a plurality of toggle balls 208 are rotatably connected to the outer wall of the rotating rod 205, the toggle balls 208 are located in the first cavity 206 and correspond vertically to the connecting holes 207, and a plurality of baffles 208 are fixedly connected to the outer wall of the rotating rod 205. 09, every two baffles 209 are located on both sides of the toggle ball 208, a magnetic block 212 is embedded in the side of the baffle 209 close to the toggle ball 208, an iron block 213 is embedded in the side of the toggle ball 208 close to the baffle 209, both ends of the rotating rod 205 are respectively fixedly connected with the first gear 300, one side of the first gear 300 is fixedly connected with the abutment rod 303, the top of the limiting groove 200 is fixedly connected with a rack 301 adapted to the first gear 300, one side of the limiting groove 200 is fixedly connected with a lifting rod 302, one end of the lifting rod 302 is trapezoidal, and a plurality of rubber strips 214 are fixedly connected to the outer wall of the toggle ball 208;
[0034] During operation, before the staff member resets the loading plate 104, the pressurizing structure is activated, so that the substrate in the storage frame 203 generates a downward force, increasing the squeezing force between the substrate and the storage frame 203. When the staff member slides the loading plate 104 to move, the abutment rod 303 moves with it and contacts the lifting rod 302. The abutment rod 303 is forced to drive the first gear 300, the rotating rod 205 and the toggle ball 208 to move upward. The toggle ball 208 moves upward to the connecting hole 207 and contacts the substrate in the storage frame 203. The gear moves upward to contact the rack 301. When the loading plate 104 moves, the rotating rod 205 can be driven to rotate by the first gear 300 and the rack 301. The toggle ball 208 on the rotating rod 205 can follow the rotating rod 200 through the suction force between the magnetic block 212 and the iron block 213. 05 rotation, when the toggle ball 208 rotates, the rubber strip 214 can drive the substrate to move on the storage frame 203. Since the toggle ball 208 is connected to the baffle 209 through the magnet and the magnetic block 212, when one corner of the substrate contacts the fixed structure, the corresponding one or more toggle balls 208 are resisted and no longer rotate. When other parts of one side of the substrate do not contact the fixed structure, the corresponding toggle ball 208 is not resisted and continues to move and adjust the position of the substrate until it fits the fixed structure with one side of the substrate and slides toward the loading plate 104. All toggle balls 208 in contact with the substrate are resisted and do not rotate, thereby achieving the effect of aligning the substrate and solving the problem of damage to the substrate when the fixed structure fixes the substrate because the four corners of the substrate are facing the fixed structure when the substrate is placed.
[0035] As a further solution of the present invention, an annular groove 210 is provided between the moving ball 208 and the rotating rod 205, and a plurality of rolling balls 211 are provided in the annular groove 210;
[0036] During operation, the plurality of rolling balls 211 can limit the position of the moving ball 208 and reduce the friction between the moving ball 208 and the rotating rod 205. Furthermore, the rolling balls 211 limit the position of the moving ball 208, and there is a certain gap between the rolling balls 211 and the baffle 209, thereby avoiding the problem of damage caused by friction between the magnetic block 212 and the iron block 213.
[0037] As a further solution of the present invention, a plurality of telescopic outer rods 304 are fixedly connected to the bottom of the first cavity 206, a telescopic inner rod 305 is slidably connected inside the telescopic outer rod 304, a limit ring 307 is fixedly connected to the top of the telescopic inner rod 305, the limit ring 307 is rotatably connected to the rotating rod 205, and a first spring 306 is fixedly connected between the telescopic inner rod 305 and the telescopic outer rod 304;
[0038] During operation, when the rotating rod 205 moves upward, the rotating rod 205 drives the telescopic inner rod 305 to move upward through the rotating ring, and the first spring 306 is stretched to generate potential energy. When the resistance rod 303 is separated from the lifting rod 302, the first spring 306 is reset and can drive the rotating rod 205 to reset through the limiting ring 307, so as to facilitate the positioning of the next batch of substrates.
[0039] As a further solution of the present invention, the boosting structure includes an air pump 400 arranged on the inner bottom surface of the main body 100, the air inlet end of the air pump 400 is connected to a pipe 401, a connection box 402 is fixedly connected to the top of the carrier plate 101, the connection box 402 is connected to the pipe 401, a plurality of connecting holes 403 are provided on the top of the connection box 402, a sliding cavity 404 is provided at the bottom of the carrier plate 104, the connection box 402 is slidably connected to the sliding cavity 404, a plurality of air inlet holes 405 are provided on the inner bottom surface of the storage frame 203, and the air inlet holes 405 penetrate the storage frame 203 and are connected to the sliding cavity 404;
[0040] During operation, the staff starts the suction pump 400, which can absorb the air on the top of the connection box 402. When the carrier plate 104 moves, the connection box 402 remains stationary, and the connection box 402 can absorb the air in the storage frame 203 through the air inlet 405. The substrate in the storage frame 203 is sucked by the suction force to achieve the above-mentioned effect of increasing the contact force between the substrate and the storage frame 203.
[0041] As a further aspect of the present invention, the fixing structure includes four second cavities 500 opened at the top of the storage frame 203, with an adjacent angle of 90 degrees for each second cavity 500.

The top contact structure moves the carrier plate 104 upward, and the storage frame 203 moves upward accordingly. The pressing plate 513 remains stationary after contacting the top plate 102. The two connecting rods 512 are stressed. The bottoms of the two connecting rods 512 move away from each other and can drive the lead screw 502 to rotate through the tooth block 510 and the second gear 503. The rotation of the lead screw 502 can drive the two first clamping plates 504 and the two second clamping plates 505 to approach each other, so as to push the substrate to the middle position of the storage frame 203 and fix the position of the substrate, achieving the effect of fixing the position of the substrate.
