Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to an auxiliary fixture for chip shear force testing. Background Technology

[0002] A chip shear force tester, also known as a chip push-pull force tester, is a device used to test and evaluate the strength and durability of semiconductor chips. It simulates the pressure that a chip may suffer in actual use by applying push and pull forces to ensure that the chip will not malfunction or be damaged during long-term use.

[0003] A jig is a tool used to assist in controlling position or movement, and is widely used in fields such as semiconductors. When performing shear force testing on chips, a jig is required to mount the chip. However, existing chip mounting methods involve placing the chip in a mounting slot and securing it with a fixing plate. This makes it impossible to adjust the jig's position on the chip. When testing different positions of the chip, the chip's placement needs to be repeatedly adjusted, especially when testing chips of different sizes. Therefore, we propose an auxiliary jig for chip shear force testing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an auxiliary fixture for chip shearing force testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: designing an auxiliary fixture for chip shearing force testing, including a fixture base, and installing a fixture bottom plate on the top of the fixture base;

[0006] Support seats are installed at both ends on one side of the fixture base. The support seats are shells with openings at the top. A pressure rod seat is built into the support seat, and a first locking bolt is threaded to one side of the support seat. The end of the first locking bolt corresponds to the pressure rod seat.

[0007] A receiving groove is provided on the inner side of the pressure rod seat, and a pressing seat is provided in the receiving groove. A through hole is provided on the top of the pressing seat, and a pressure rod is placed in the through hole. The end of the pressure rod near the bottom plate of the fixture is bent downward. A second locking bolt is threaded to the top of the pressing seat. The end of the second locking bolt is placed in the through hole and corresponds to the outer wall of the pressure rod.

[0008] Preferably, a rubber head is installed on the end of the pressure bar near the base plate of the fixture.

[0009] Preferably, a limiting groove is provided at the top of the fixture base plate, and the limiting groove extends through the end of the fixture base plate.

[0010] Preferably, the receiving groove extends through the side of the pressure rod seat away from the fixture base and the top of the pressure rod seat, the clamping seat is rotatably installed in the receiving groove, and a third locking bolt is threaded to the bottom of the clamping seat, the end of the third locking bolt corresponding to the inner wall of the receiving groove.

[0011] Preferably, the pressure rod seat is rotatably mounted inside the support seat.

[0012] Preferably, mounting holes are provided at the corners of the fixture base.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application:

[0014] 1. The chip shear force testing auxiliary fixture can adjust the position of the end of the pressure rod by rotating the pressure rod seat on the support seat and sliding the pressure rod in the through hole, so as to fix the chip placed on the upper end of the fixture base plate in a more targeted manner.

[0015] 2. The chip shear force testing auxiliary fixture can drive the pressure rod to deflect by rotating the clamping seat in the receiving groove. With the adjustment of the pressure rod's position, it realizes the loosening and clamping operations when fixing the chip. Attached Figure Description

[0017] In the figure: 1. Fixture base; 2. Fixture base plate; 3. Support seat; 4. Pressure rod seat; 5. First locking bolt; 6. Receiving groove; 7. Pressure seat; 8. Third locking bolt; 9. Through hole; 10. Pressure rod; 11. Second locking bolt; 12. Limiting groove. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1 A chip shear force testing auxiliary fixture includes a fixture base 1, with mounting holes at each corner of the fixture base 1 for mounting the fixture base 1 on a chip shear force testing device.

[0020] A fixture base plate 2 is installed on the top of the fixture base 1. A limiting groove 12 is opened on the top of the fixture base plate 2. The limiting groove 12 passes through the end of the fixture base plate 2. When the fixture base plate 2 holds the chip, the chip is placed in the limiting groove 12. The limiting groove 12 will limit the chip, which can improve the stability of the chip placed on the fixture base plate 2.

[0021] Support seats 3 are installed at both ends of one side of the fixture base 1. The support seats 3 are shells with an opening at the top. A pressure rod seat 4 is installed inside the support seat 3. The pressure rod seat 4 is rotatably installed inside the support seat 3, allowing the pressure rod seat 4 to rotate freely inside the support seat 3. A first locking bolt 5 is threadedly connected to one side of the support seat 3. The end of the first locking bolt 5 corresponds to the pressure rod seat 4, locking and fixing the pressure rod seat 4 after rotation adjustment.

[0022] A receiving groove 6 is provided on the inner side of the pressure rod seat 4, extending through the side of the pressure rod seat 4 away from the fixture base 1 and the top of the pressure rod seat 4. A clamping seat 7 is provided in the receiving groove 6, wherein the clamping seat 7 is rotatably installed in the receiving groove 6, allowing the clamping seat 7 to deflect within the receiving groove 6, and a third locking bolt 8 is threadedly connected to the bottom of the clamping seat 7, the end of the third locking bolt 8 corresponding to the inner wall of the receiving groove 6, locking and fixing the deflected clamping seat 7. A [missing information - likely a design element] is provided on the top of the clamping seat 7. There is a through hole 9, and a pressure rod 10 is installed inside the through hole 9, allowing the pressure rod 10 to slide freely within the through hole 9, thereby adjusting the position of the end of the pressure rod 10 on the fixture base plate 2. The end of the pressure rod 10 near the fixture base plate 2 is bent downwards. A second locking bolt 11 is threadedly connected to the top of the clamping seat 7. The end of the second locking bolt 11 is placed inside the through hole 9 and corresponds to the outer wall of the pressure rod 10. After adjusting the position of the pressure rod 10, the second locking bolt 11 can be rotated to lock and fix the pressure rod 10.

[0023] Specifically, when the chip is placed in the limiting groove 12, the clamping seat 7 can be deflected, thereby moving the pressure rod 10 away from the fixture base plate 2, providing sufficient space on the fixture base plate 2 for placing the chip in the limiting groove 12. After the chip is placed, the pressure rod 10 can be rotated back onto the fixture base plate 2. By pulling the pressure rod 10 to slide in the through hole 9 and adjusting the pressure rod seat 4 to rotate on the support seat 3, the position of the pressure rod 10 on the chip can be adjusted. Then, by rotating the clamping seat 7 again, the end of the pressure rod 10 is pressed tightly against the chip, and the second locking bolt 11 and the third locking bolt 8 are locked, thus fixing the chip placed in the limiting groove 12. In this way, the multi-position fixing effect of the pressure rod 10 on the chip is improved by the multi-angle movement and adjustment of the pressure rod 10.

[0024] In order to buffer the downward pressure of the pressure rod 10 on the chip, a rubber head is installed on the end of the pressure rod 10 near the fixture base plate 2. This not only ensures the fixing effect of the pressure rod 10 on the chip, but also buffers the squeezing of the pressure rod 10.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
