DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to the accompanying drawings Figures 1-11 , the present application provides the following technical solutions.

[0019] A chip packaging structure with calibration function includes a chip body 1. Pin connecting strips 2 are horizontally arranged on all four sides of the chip body 1. Several connecting contact points 7 are provided at the lower end of each pin connecting strip 2. An arranging strip 3 is horizontally inserted into the pin connecting strip 2 via a calibration component. An assembly groove 8 is opened at the lower end of the arranging strip 3. A clamping control box 9 is horizontally inserted into the assembly groove 8. Several slots 18 are symmetrically arranged on both sides of the clamping control box 9. A snap-fit ​​spring 17 is embedded on the side of each assembly groove 8 near the slot 18, and one side of the snap-fit ​​spring 17 is inserted into the slot 18. The clamping control box 9 and the arranging strip 3 are detachably connected. The engagement of the snap-fit ​​spring 17 and the slot 18 allows for simple positioning after the clamping control box 9 is inserted into the arranging strip 3.

[0020] The fitting and pressing components are designed to ensure better contact between the chip pins 5 and the connecting contact points 7. The upper half of the arranging strip 3 is fitted with several chip pins 5, and one side of each chip pin 5 passes through the pin connecting strip 2. The lower end of the arranging strip 3 away from the chip body 1 has an overlapping strip 25 with several overlapping grooves 26. One end of the chip pin 5 placed inside the pin connecting strip 2 passes around the arranging strip 3 and is inserted into the overlapping groove 26. Several recessed grooves 4 are provided on the arranging strip 3. The side of the chip pin 5 that contacts the arranging strip 3 is embedded in the 4. The position where the chip pin 5 contacts the arranging strip 3 is recessed by the recessed grooves 4. When pressing the chip pin 5 later, the recessed grooves 4 can achieve more stable support.

[0021] The bonding and pressing assembly is located at the lower end of the arrangement strip 3. The bonding and pressing assembly includes a pressing control box 9, a synchronization tube 12, and several cam disks 13, with the cam disks 13 corresponding to several chip pins 5. A horizontal through groove 10 is horizontally opened at the center of the upper end of the pressing control box 9. A contact area 6 is provided at the lower end of one side of the chip pins 5 surrounding the arrangement strip 3. The contact area 6 is in contact with the connecting contact point 7. Through grooves 11 are opened through one side of the contact area 6 in the horizontal through groove 10. The synchrotron tube 12 is provided on one side of the synchrotron tube 12 located in the cam disk 13. The protruding side of the cam disk 13 passes through and presses against the control box 9 and abuts against the side of the contact area 6. The synchrotron tube 12 can rotate in the horizontal through groove 10, and the cam disk 13 can rotate in the through rotating groove 11. Therefore, when the synchrotron tube 12 rotates, several cam disks 13 can rotate at the same time. When the protruding side of the cam disk 13 is far away from the contact area 6 of the chip pin 5, it is stored in the through rotating groove 11.

[0022] The lower end of the clamping control box 9 extends out of the arranging strip 3 and is provided with a protruding strip. Several mating slots 27 are horizontally opened through the protruding strip. The mating slots 27 are offset from the through-rotation slot 11. Several mating inserts 20 are horizontally provided on one side of the vertical section of the L-shaped constraint strip 19. Several mating inserts 20 are horizontally inserted into several mating slots 27. The upper and lower sides of the arranging strip 3 are in contact with the lower side of the horizontal section of the L-shaped constraint strip 19 and the upper side of the mating inserts 20, respectively. Two combination bolts 21 are vertically inserted through both sides of the L-shaped constraint strip 19. The lower ends of the combination bolts 21 are threaded through the arranging strip 3 and the clamping control box 9, respectively, and then connected to the mating inserts 20. When the L-shaped constraint strip 19 is connected to the arranging strip 3, it surrounds the arranging strip 3 on three sides with the mating inserts 20 and its own structure. Then, the arranging strip 3 and the L-shaped constraint strip 19 are fixed by the pin connecting strip 2 to ensure the stable connection between the chip pin 5 and the arranging strip 3. At the same time, it can facilitate the replacement and maintenance of the chip pin 5 in the future.

[0023] While both sides of the L-shaped constraint strip 19 are attached to the arrangement strip 3, they constrain the state of the chip pin 5 inserted into the recessed groove 4. The upper end of the L-shaped constraint strip 19 is in contact with the upper inner side of the pin connecting strip 2, and the lower end of the L-shaped constraint strip 19 and the lower end of the overlapping strip 25 are in contact with the lower inner side of the pin connecting strip 2. The L-shaped constraint strip 19, together with the overlapping strip 25, can move stably horizontally within the pin connecting strip 2.

[0024] The calibration assembly includes an L-shaped constraint bar 19, two calibration control blocks 16, and two calibration bolts 24. A first prismatic groove is formed through the center of the synchronization tube 12. A prismatic synchronization rod 14 is horizontally and movably inserted into the first prismatic groove. Rotation slots are formed on both sides of the horizontal through slot 10 in the assembly groove 8. A T-shaped rotating block 15 is movably inserted through the arrangement strip 3 in the rotation slot. The two calibration control blocks 16 are respectively located on one side of the T-shaped rotating block 15 through the arrangement strip 3. A second prismatic groove is formed through the center of the calibration control block 16 through the T-shaped rotating block 15. The two sides of the prismatic synchronization rod 14 are respectively inserted into the two second prismatic grooves. The length of the prismatic synchronization rod 14 is less than the horizontal length between the two calibration bolts 24. When the calibration control block 16 is rotated, the rotation control of the synchronization tube 12 and the cam disk 13 can be achieved through the prismatic synchronization rod 14, thereby realizing the contact area 6 of the chip pin 5 and the contact point 7.

[0025] A calibration hole 23 is provided on one side of the calibration control block 16. The calibration hole 23 is oriented in the same direction as the protruding side of the cam disk 13. End plates 22 are inserted into both sides of the calibration control block 16 inside the pin connecting strip 2. The calibration control block 16 is movably inserted through the end plates 22. Two calibration bolts 24 are vertically inserted into both sides of the pin connecting strip 2. The lower ends of the two calibration bolts 24 are respectively inserted through the end plates 22 and the calibration holes 23 of the calibration control block 16. The calibration bolts 24 can only pass through the calibration holes 23 when the calibration holes 23 of the calibration control block 16 are aligned with the holes for installing the calibration bolts 24. When the calibration bolts 24 can pass through the calibration holes 23, the calibration and positioning of the chip pin 5 and the connection contact point 7 have been completed. Then, with the pressing force of the cam disk 13, the connection stability of the chip pin 5 and the connection contact point 7 during later use is ensured.

[0026] A packaging process for a chip packaging structure with calibration function includes the following steps: Step 1: When connecting the chip pin 5 to the chip body 1, first insert the clamping control box 9 into the arrangement strip 3 through the snap-fit ​​spring 17 and the snap-fit ​​slot 18, then insert the chip pin 5 into the recessed slot 4 of the arrangement strip 3 in sequence, and semi-enclose it on the arrangement strip 3. Step 2: Then take out the L-shaped constraint strip 19 and fit it onto the arrangement strip 3 from one side. At the same time, insert several mating strips 20 into several mating slots 27 to fix the position of the chip pin 5 connected to the arrangement strip 3. Then, use the combination bolts 21 to constrain and fix the connection between the clamping control box 9 and the arrangement strip 3, as well as the connection between the L-shaped constraint strip 19 and the arrangement strip 3. Step 3: Insert the entire assembly of the arrangement bar 3 and the L-shaped constraint bar 19 from one side of the pin connection bar 2 and move it to approximately the desired position. At this time, the calibration control block 16 and the prismatic synchronization rod 14 are rotated by the second prismatic slot on the calibration control block 16, so that the protruding side of the cam disk 13 extends out to press the control box 9 and squeeze the contact area 6, so that the contact area 6 of the chip pin 5 is tightly fitted with the connection contact point 7. Step 4: Finally, insert the two end plates 22 into the two ends of the pin connector 2 and fit them onto the calibration control block 16. At this time, when the calibration bolt 24 can pass vertically through the end plate 22 and the calibration hole 23 of the calibration control block 16, it means that the contact area 6 of several chip pins 5 is precisely connected with the contact point 7. When disassembling later, the operation is reversed. First, remove the calibration bolt 24, then pull out the L-shaped constraint strip 19 and the arrangement strip 3 as a whole, and then remove the combination bolt 21 to separate the L-shaped constraint strip 19 from the arrangement strip 3. At this time, through the metal elasticity of the chip pin 5 itself, the damaged chip pin 5 can be disassembled and replaced with a new chip pin 5 and fitted onto the arrangement strip 3.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
