Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to an easily adjustable chip testing workbench. Background Technology

[0002] A chip testing workbench is a specialized equipment platform for chip testing. When developing new chips, researchers use the testing workbench to perform various performance tests and characteristic analyses on chip samples. When exploring new chip materials or architectures, the workbench is used to conduct comprehensive tests on the electrical, optical, and thermal properties of the chip using a variety of testing instruments. Experimental data is obtained to evaluate the feasibility of new designs and optimization directions, providing experimental data support and a verification platform for chip technology innovation.

[0003] However, existing technologies still have the following problems:

[0004] First, when using an electron microscope for inspection, only a specific angle area on the chip surface can be observed. It is inconvenient to observe some tiny defects hidden at a specific angle, such as short circuits on the bottom or side of the chip, or tiny material peelings. It is also inconvenient to adjust the angle of the chip, making it less practical.

[0005] Secondly, during the rotation of the chip device, positional shift can easily occur, causing the detection focus to deviate from the target area, making it impossible to clearly observe the microscopic features of the chip. The movement of the chip position may cause poor contact between the probe and the pin, making it inconvenient to clamp and fix the chip, which will affect the transmission of electrical signals and the accuracy of measurement, thus generating erroneous detection data.

[0006] To address the aforementioned problems, the inventors proposed an easily adjustable chip testing stage. Summary of the Invention

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.

[0020] Example: Figure 1-4As shown, this utility model provides an easily adjustable chip testing workbench, including a tabletop 1. Multiple support rods 4 arranged in a rectangular array are fixedly connected to the top surface of the tabletop 1. A top plate 5 is fixedly connected to the top surface of the support rods 4. Multiple cameras 6 arranged at equal intervals are fixedly connected to the bottom surface of the top plate 5. An adjustment device 2 is fixedly connected to the top surface of the tabletop 1. The adjustment device 2 includes a base 201, a first rotating shaft 202 rotatably connected to the lower end of the base 201, and a motor 203 fixedly connected to one side of the base 201. The output end of the motor 203 extends into the base 201 and is fixedly connected to the first rotating shaft 202. The upper end of the base 201 is symmetrically provided with a first through groove 204. A connecting plate 205 is fixedly sleeved on the outer surface of the first rotating shaft 202. When the motor 203 is started, its output end begins to rotate, driving the first rotating shaft 202 to rotate. As the first rotating shaft 202 rotates, the connecting plate 205 also rotates. A rotating plate 206 is fixedly connected to the top surface of the connecting plate 205. The upper end of the base 201 is in contact with the lower end of the rotating plate 206.

[0021] The top surface of the rotating plate 206 is snapped with a base plate 209. The top surface of the rotating plate 206 has multiple equally spaced sliding grooves 207. The inner wall of the sliding grooves 207 is slidably connected to a slider 208. The top surface of the slider 208 is fixedly connected to the base plate 209. The slider 208 slides in the sliding grooves 207, ensuring the stability of the base plate 209 as it rotates with the rotating plate 206, preventing it from shifting or becoming unstable. During the rotation of the rotating plate 206, the chip that is clamped and fixed will rotate. A fixing block 210 is symmetrically fixedly connected to one side of the base 201. A bolt 211 is threaded through the inner wall of the fixing block 210. The bottom end of the bolt 211 extends into the table 1. Tightening the bolt 211 will firmly fix the base 201 to the position of the table 1. The top surface of the base plate 209 is fixedly connected with multiple clamping devices 3 arranged in a rectangular array.

[0022] The clamping device 3 includes symmetrically distributed support blocks 31, with a second rotating shaft 32 rotatably connected between the support blocks 31. An extrusion plate 33 is movably passed through the outer surface of the second rotating shaft 32. A hole 34 is opened on one side of the extrusion plate 33, located at the eccentricity of the extrusion plate 33. The second rotating shaft 32 is located inside the hole 34. Pulling the pull rod 35 causes the extrusion plate 33 to rotate around the second rotating shaft 32. The pull rod 35 is fixedly connected to the outer surface of the extrusion plate 33. A clamping block 36 is movably sleeved on the outer surface of the second rotating shaft 32, and the clamping block 36 is located between the support blocks 31.

[0023] When the extrusion plate 33 rotates, it pushes the clamping block 36 to rotate around the second rotating shaft 32. The top surface of the clamping block 36 has a second through groove 37. The outer surface of the extrusion plate 33 is in contact with the inner wall of the second through groove 37. A limiting groove 38 is symmetrically opened on one side of the clamping block 36. The outer surface of the second rotating shaft 32 is in contact with the inner wall of the limiting groove 38. The contact between the inner wall of the limiting groove 38 and the limiting groove 38 can limit the range and direction of the clamping block 36's rotation around the second rotating shaft 32. A slot 39 is opened on one side of the clamping block 36. The clamping block 36 is pressed between the support blocks 31 by the second rotating shaft 32 and slides. The clamping block 36 clamps the chip in the inner wall of the slot 39, preventing the chip from shifting position during the detection process.

[0024] Working principle: Tighten bolt 211 to firmly fix base 201 on table 1. Start motor 203, its output end starts to rotate and drives first rotating shaft 202 to rotate. As first rotating shaft 202 rotates, connecting plate 205 also rotates. Rotating plate 206 fixedly connected to the top surface of connecting plate 205 rotates synchronously. Slider 208 slides in slide groove 207 to ensure the stability of base plate 209 during rotation with rotating plate 206 and prevent it from shifting or becoming unstable. During the rotation of rotating plate 206, the clamped chip will rotate, thereby achieving the purpose of effectively adjusting the angle of the chip.

[0025] Pulling the lever 35 causes the extrusion plate 33 to rotate around the second shaft 32. Since the hole 34 is in an eccentric position, the rotation of the extrusion plate 33 will push the clamping block 36 to rotate around the second shaft 32 accordingly. The second shaft 32 achieves rotational connection. The inner wall of the limiting groove 38 fits together, which can limit the range and direction of the clamping block 36's rotation around the second shaft 32. The clamping block 36 is pressed between the support blocks 31 by the second shaft 32 and slides. The clamping block 36 clamps the chip in the inner wall of the slot 39, thereby achieving the purpose of preventing the chip from shifting position during the detection process.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
