[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figures 1-6 The chip packaging structure shown includes an electrical connection limiting frame 1. An electrical connection slot 2 is provided inside the electrical connection limiting frame 1, and the electrical connection slot 2 is formed inside four inner walls. Multiple electrical connection holes 3 are connected to the outside of the electrical connection slot 2, and the multiple electrical connection holes 3 are respectively formed inside the four side walls of the electrical connection limiting frame 1. Multiple connecting pins 4 are connected to the four side walls of the electrical connection limiting frame 1 through the multiple electrical connection holes 3, and the multiple connecting pins 4 are respectively inserted into the multiple electrical connection holes 3. Stacked limiting frames 5 are clamped at both the top and bottom of the electrical connection limiting frame 1. Connecting electrodes 6 are provided inside both the electrical connection limiting frame 1 and the stacked limiting frames 5. Integrated chips 7 are attached to the top and bottom of the connecting electrodes 6. Since the integrated chip 7 is relatively fragile and needs to be connected to external circuits, it needs to be packaged to achieve the desired connection between the chip and the external circuitry. The system provides connection, support, and protection between multiple integrated chips 7. Integrated chips 7 are supported by electrical connection limiting frames 1 and stacking limiting frames 5, and multiple integrated chips 7 are connected through multiple connecting electrodes 6. Finally, the connecting electrodes 6, which are snapped into the electrical connection limiting frames 1, are connected to multiple connecting pins 4, which are snapped into the side wall, and are connected to external circuits through the multiple connecting pins 4. The connecting electrodes 6 are snapped into the electrical connection limiting frames 1 through electrical connection slots 2, and the multiple connecting pins 4 are connected to the connecting electrodes 6 through multiple electrical connection sockets 3, which communicate with the electrical connection slots 2. This allows multiple integrated chips 7 to be stacked vertically through the electrical connection limiting frames 1 and stacking limiting frames 5, and to be connected through the multiple connecting electrodes 6. Furthermore, the number of stacked layers of multiple integrated chips 7 can be increased or decreased by adding or removing stacking limiting frames 5.

[0031] Preferably, the electrical connection limiting frame 1 and the stacking limiting frame 5 are made of insulating material. The four side walls of the electrical connection limiting frame 1 are flush with the four side walls of the stacking limiting frame 5, and the four inner walls of the electrical connection limiting frame 1 are flush with the four inner walls of the stacking limiting frame 5. This allows the electrical connection limiting frame 1 and the stacking limiting frame 5 to support multiple integrated chips 7 while also isolating them internally to prevent external interference and thus protect the multiple integrated chips 7.

[0032] Preferably, each of the multiple connecting electrodes 6 has a connecting line etched inside, so that multiple connecting pins 4 are connected to the multiple connecting electrodes 6 through the connecting line, and are connected to multiple integrated chips 7 through the multiple connecting electrodes 6. Moreover, the connecting electrodes 6 can adapt to the connection between different types of integrated chips 7 by changing the internally etched connecting lines.

[0033] Preferably, the lower end of the stacking limiting frame 5 has an electrical board slot, and the connecting electrode 6 is snapped into the electrical board slot of the stacking limiting frame 5, so that the connecting electrode 6 located inside the stacking limiting frame 5 can be supported and protected by the stacking limiting frame 5, and can be limited by the electrical board slot of the stacking limiting frame 5, so that the connecting electrode 6 can be accurately attached and connected to the integrated chip 7.

[0034] Preferably, multiple integrated chips 7 are respectively snapped into the inner ends of the upper and lower ends of the electrical connection limiting frame 1 and the inner end of the stacked limiting frame 5 away from the connecting pin 4. The outer walls of the multiple integrated chips 7 are respectively flush with the outer walls of the upper and lower ends of the electrical connection limiting frame 1 and the outer wall of the stacked limiting frame 5 away from the electrical connection limiting frame 1. This ensures that the outer walls of the upper and lower ends of the electrical connection limiting frame 1 and the stacked limiting frame 5 do not obstruct the bonding connection between the integrated chips 7 and the connecting electrode 6, so that the multiple integrated chips 7 can be tightly bonded to the connecting electrode 6, ensuring a stable connection between the multiple integrated chips 7.

[0035] Preferably, multiple integrated chips 7 are connected to two connecting electrodes 6 at the top and bottom ends respectively through multiple connecting posts 8. The multiple connecting posts 8 pass through the outer interior of the upper and lower ends of the multiple connecting electrodes 6 and the inner interior of the outer walls of the upper and lower ends of the multiple integrated chips 7. Since the multiple connecting posts 8 inside the connecting surfaces between the mutually attached connecting electrodes 6 and integrated chips 7 correspond one-to-one, the connecting electrodes 6 and integrated chips 7 can be connected through the one-to-one corresponding multiple connecting posts 8, which can not only make the connection between the connecting electrodes 6 and integrated chips 7 more convenient, but also make the connection between the connecting electrodes 6 and integrated chips 7 more precise.

[0036] Preferably, limit slots 9 are provided on the inner outer sides of the upper and lower ends of the electrical connection limit frame 1 and on the inner outer side of the stacked limit frame 5 away from the electrical connection limit frame 1. The stacked limit frame 5 can be engaged with the electrical connection limit frame 1 through the circuit board slot and the limit slot 9, so that the electrical connection limit frame 1 and the stacked limit frame 5, and the stacked limit frame 5 and the stacked limit frame 5 can be engaged with each other through the circuit board slot and the limit slot 9. This restricts the position between the electrical connection limit frame 1 and the multiple stacked limit frames 5, so that the connecting electrode 6 and the integrated chip 7 inside the multiple stacked limit frames 5 can be accurately connected, ensuring the stable connection between the multiple integrated chips 7. After the multiple integrated chips 7 are connected, the entire connection is encapsulated, and multiple connecting pins 4 are exposed during encapsulation, so that the encapsulated chip can be connected to the external circuit through the multiple connecting pins 4.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
