[0002] Gallium nitride (GaN) is a composite semiconductor material composed of nitrogen and gallium elements, and is hailed as one of the most important semiconductor materials after silicon.
[0003] SOC testing is a series of verification and inspection processes conducted to ensure that all functions, performance, reliability, and security of highly integrated chips meet design specifications after manufacturing. It aims to screen out chips with manufacturing defects (commonly known as "bad chips") in the shortest time and at the lowest cost, ensuring that only "good chips" are delivered to customers.
[0004] Currently, when performing docking tests on gallium nitride (GaN) chips, the existing test sockets are not suitable for testing a large number of chips due to the large number of chips and the need for auxiliary alignment and point finding each time GaN chips are installed into the test socket.

[0016] The beneficial effects of this invention are:
[0017] First, this invention uses a lead screw to rotate, which causes the horizontal plate to rise as a whole, allowing the extended alignment plate to contact the second piston rod. This causes the gallium nitride semiconductor chip on the blocking plate to fall onto the receiving plate. Simultaneously, the irregular bracket can drive the third rack to move to the side, preventing the second gear from contacting the third rack when the horizontal plate moves downward. Furthermore, as the horizontal plate moves downward, the pins of the gallium nitride semiconductor chip can be inserted into the test slots in the test socket. The first rack can also drive the third gear and the reinforcing frame to rotate simultaneously, allowing the reinforcing frame to press the pins on the gallium nitride semiconductor chip, thus completing the precise chip docking.
[0018] Second, when the horizontal plate moves upward, it can drive the second gear to move and contact the third rack, so that the second gear can drive the first gear to rotate in the opposite direction. Thus, the second rack can drive the limiting plate to be pulled out from the bottom of the receiving plate. At this time, the receiving plate will be in an inclined state, and the tested gallium nitride semiconductor chip can slide down onto the receiving cavity for collection. Furthermore, when the second gear passes the third rack, the limiting plate can automatically reset, so that the limiting plate can support the receiving plate in a horizontal state, which is convenient for receiving gallium nitride semiconductor chips again, thus completing the work of guiding and discharging gallium nitride semiconductor chips.

The second rack 25 meshes with the first gear 26. The outer ring surface of the cam 37 is in contact with the surface of the extension base 47 away from the positioning top frame 46.

The front end surface of the limiting base frame 31 is set at a 45° angle. The limiting base frame 38 is vertically aligned with the rear support 17.
[0040] The working principle of Example 1 is as follows: In use, the gallium nitride semiconductor chip 3 is first placed on the top of the two barrier plates 5. A drive motor is installed at the bottom of the support base 39, and the lead screw 41 passes through the support base 39 and is connected to the drive motor. The drive motor can be started to drive the lead screw 41 to rotate. The horizontal plate 21 is threaded onto the outer ring of the lead screw 41, so that the lead screw 41 can drive the horizontal plate 21 to move upward. At this time, the horizontal plate 21 is slidably sleeved on the outer ring of the guide rod 42, so that the horizontal plate 21 can be guaranteed to move up and down in a straight line. Subsequently, when the horizontal plate 21 moves upward, it can drive the extension alignment plate 23 to move to contact the second piston rod 11, thereby squeezing the second piston rod 11 into the interior of the L-shaped air cylinder 10. At the same time, when the second piston rod 1 When the first piston rod 8 enters the L-shaped air cylinder 10, it can be squeezed to move outward from the inside of the L-shaped air cylinder 10. This allows the first piston rod 8 to drive the partition 13 to move away from the conveyor table 4. At the same time, when the horizontal plate 21 moves upward to its limit position, the receiving plate 16 can contact the through hole at the bottom of the conveyor table 4, and the blocking plate 5 can be misaligned from the bottom of the gallium nitride semiconductor chip 3. At this time, the gallium nitride semiconductor chip 3 can fall onto the receiving plate 16 through the through hole inside the conveyor table 4, completing the placement of the gallium nitride semiconductor chip 3. Furthermore, while the partition 13 is displaced, it can also drive the irregular bracket 9 to push the magnetic sleeve 45 to move closer to the push plate 43, so that the third rack 44 can be misaligned with the second gear 28, preventing the horizontal plate 21 from moving further away. When moving downwards, the second gear 28 contacts the third rack 44. Subsequently, as the horizontal plate 21 moves downwards, it can drive the pins of the gallium nitride semiconductor chip 3 to insert into the test socket 35. The second spring 22 allows the horizontal plate 21 to continue moving downwards, thus enabling the first rack 20 to mesh with the third gear 40. This allows the third gear 40 and the reinforcing frame 36 to rotate as the horizontal plate 21 continues to move downwards. When the cam 37 rotates, the protruding part can rotate to contact the extension base 47, allowing the extension base 47 to be displaced. This allows the push plate 43 to push the magnetic sleeve 45 back to its original position, facilitating the subsequent upward movement of the horizontal plate 21. During this process, the second gear 28 contacts the third rack 44, and when the horizontal plate 21 moves downwards to its limit position... When in position, the reinforcing frame 36 can rotate to contact the pins of the gallium nitride semiconductor chip 3, thereby pressing the pins and confining the gallium nitride semiconductor chip 3 to the test socket 35, improving the testing stability of the gallium nitride semiconductor chip 3. At this time, the test socket 35 can be energized to perform performance testing on the gallium nitride semiconductor chip 3. After the gallium nitride semiconductor chip 3 has been tested, the drive motor at the bottom of the support base 39 can be restarted, causing the lead screw 41 to rotate in the opposite direction, so that the horizontal plate 21 can move upward again. At this time, the horizontal plate 21 will drive the first rack 20 to move upward, so that the third gear 40 can drive the cam 37 and the reinforcing frame 36 to rotate in the opposite direction, and the reinforcing frame 36 can disengage from the pins on the gallium nitride semiconductor chip 3.The protruding part of the cam 37 can disengage from the extension base 47. Subsequently, when the horizontal plate 21 moves upward, the contact guide rod 19 can press the rear support 17 upward, thereby supporting the receiving plate 16 to move upward. When the second gear 28 moves to contact the third rack 44, the second gear 28 can drive the first gear 26 to rotate. When the first gear 26 rotates, it can drive the second rack 25 to move to the rear, so that the limiting base plate 32 can move to the rear until the limiting base plate 32 moves out from the bottom of the receiving plate 16. At this time, the receiving plate 16 will lose the restriction of the limiting base plate 32 and rotate downward. The limiting base 31 is mounted on the supporting horizontal plate 33. The bottom end of the receiving plate 16 is tilted, allowing it to be placed at an angle. Simultaneously, the receiving plate 16 can move above the receiving cavity 34. When the receiving plate 16 is tilted, the tested gallium nitride semiconductor chip 3 can slide down along the receiving plate 16 and fall into the receiving cavity 34. Subsequently, when the horizontal plate 21 drives the second gear 28 to move past the third rack 44, the elasticity of the third spring 30 will cause the limiting base plate 32 to move forward and reset, allowing the limiting base plate 32 to move to the bottom end of the receiving plate 16. This supports the receiving plate 16 in a horizontal position, facilitating the reception of the gallium nitride semiconductor chip 3 again, thus completing the operation.
[0041] Example 2
[0042] Based on Embodiment 1, as shown in Figure 8, the conveyor table 4 also includes an interception cavity 48 and a plastic pad 49. The plastic pad 49 is fixedly installed at the bottom inside the conveyor table 4, and the interception cavity 48 is fixedly installed at the bottom inside the plastic pad 49.
[0043] In this embodiment, a plastic pad 49 is placed at the bottom front end of the receiving cavity 34, and the receiving cavity 34 is tilted at 30°. This allows the gallium nitride semiconductor chip 3 to slide down along the receiving cavity 34 and be temporarily placed inside the plastic pad 49. The plastic pad 49 prevents the gallium nitride semiconductor chip 3 from falling. Furthermore, an intercepting cavity 48 is installed at the bottom inside the plastic pad 49 to prevent the gallium nitride semiconductor chip 3 from being bumped or knocked when it falls, thus completing the operation.
[0044] Example 3
[0045] Based on Embodiment 1, as shown in Figures 9, 10, and 11, a synchronization device 50 is symmetrically fixedly installed at the top of the test socket 35. The synchronization device 50 includes a first support cavity 51, a limiting spring 52, a movable vertical frame 53, a Z-shaped bracket 54, a voltage detection component 55, a contact electrode plate 56, a temperature sensor 57, an alignment rod 58, a second support cavity 59, a pressure sensor 60, and a guide spring 61. The limiting spring 52 is fixedly installed inside the first support cavity 51, the movable vertical frame 53 is fixedly installed at one end of the limiting spring 52, and the Z-shaped bracket 54 is fixedly installed on the side of the movable vertical frame 53 away from the limiting spring 52. The measuring component 55 is fixedly installed on the Z-shaped bracket 54 at the end away from the movable vertical frame 53. The contact electrode 56 is fixedly installed on the side end of the voltage measuring component 55. The second support cavity 59 is symmetrically fixedly installed on the side end of the voltage measuring component 55 near the contact electrode 56. The temperature sensor 57 is slidably inserted into the end of the second support cavity 59 away from the voltage measuring component 55. The alignment rod 58 is fixedly installed on the end of the temperature sensor 57 near the voltage measuring component 55. The pressure sensor 60 is fixedly installed inside the second support cavity 59 away from the temperature sensor 57. The guide spring 61 is fixedly installed between the second support cavity 59 and the temperature sensor 57.
[0046] In this embodiment, the movable vertical bracket 53 is located between the cam 37 and the extension base 47. When the cam 37 rotates, the protruding end can drive the extension base 47 and the movable vertical bracket 53 to move simultaneously. When the movable vertical bracket 53 moves, it can be moved by the Z-shaped bracket 54. When the Z-shaped bracket 54 moves, it can drive the temperature sensor 57 to contact the surface of the gallium nitride semiconductor chip 3. Subsequently, when the movable vertical bracket 53 continues to move, the guide spring 61 allows the temperature sensor 57 to enter the interior of the second support cavity 59. When the temperature sensor 57 moves to contact the pressure sensor 60, the contact electrode 56 can contact the pin on the side of the gallium nitride semiconductor chip 3. Simultaneously, the pressure sensor 60 is electrically connected to the voltage detection component 55 and the temperature sensor 57, allowing them to operate synchronously. Therefore, when the contact electrode 56 contacts the pin of the gallium nitride semiconductor chip 3, the voltage fluctuation of the gallium nitride semiconductor chip 3 during operation can be measured. At the same time, when the temperature sensor 57 contacts the surface of the gallium nitride semiconductor chip 3, it can measure... The operating temperature of the gallium nitride semiconductor chip 3 is obtained. Through the temperature sensor 57 and voltage detection component 55, the voltage and operating temperature of the gallium nitride semiconductor chip 3 can be detected, realistically simulating its operating state. Subsequently, when the cam 37 resets, it disengages from the movable vertical bracket 53, causing the movable vertical bracket 53 to lose pressure. At this time, the elasticity of the limit spring 52 will drive the movable vertical bracket 53 to move and reset, thereby allowing the contact electrode plate 56 and temperature sensor 57 to disengage from the gallium nitride semiconductor chip 3. After the gallium nitride semiconductor chip 3 is subsequently removed from the interior of 35, the temperature sensor 57 is offset from the support pin on the side of the gallium nitride semiconductor chip 3 to avoid contact between the temperature sensor 57 and the support pin of the gallium nitride semiconductor chip 3, thereby improving the accuracy of the temperature sensor 57 during measurement. After the temperature sensor 57 is reset, it can drive the alignment rod 58 to disengage from the pressure sensor 60, so that the temperature sensor 57 and the voltage detection component 55 can be de-energized, avoiding prolonged operation of the voltage detection component 55 and the temperature sensor 57, thus completing the work.
