Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor testing technology, and in particular to a detachable probe card connection assembly. Background Technology
[0002] Probe cards are the interface between the chip under test and the testing machine in semiconductor wafer testing. They are core consumables for semiconductor testing. They are mainly used to perform preliminary electrical performance tests on chips before packaging, screen out defective chips, and then proceed with the subsequent packaging process. Probe card connection components are required when testing chips.
[0003] As a key auxiliary structure in the probe card system, the detachable probe card connection assembly plays a crucial role in enabling rapid, stable, and repeatable connection and disconnection between the probe card and the testing equipment, while ensuring the reliability of signal transmission during testing. In the existing installation process, due to human error or unreasonable structural design, it is difficult to guarantee the precise alignment between the probe and the chip or other components. For example, the axial accuracy between the test probe and the precision load sensor is difficult to guarantee. The new probe card microcantilever module has good mechanical stability and can maintain stable performance even in extreme high-temperature welding environments, ensuring that the probe card connection assembly can work normally under complex working conditions. However, the improved probe card connection assembly is difficult to disassemble. Utility Model Content

A fixing plate 2 is fixedly connected to the left side of the outer wall of the fixing post. The fixing plate 2 is fixedly connected to the left side of the inner wall of the housing 2.
[0007] As a further description of the above technical solution: Anti-slip pads are fixedly connected to the lower ends of the outer walls of the four feet of the workbench, and corner protectors are fixedly connected to the four corners of the top wall of the workbench.
[0008] As a further description of the above technical solution: The workbench has a base plate fixedly connected to the left and right sides of its top wall, and the base plate has uprights fixedly connected to the front and rear sides of its top wall.
[0009] As a further description of the above technical solution: A display is fixedly connected to the front of the top wall of the workbench, and buttons are installed on the front of the outer wall of the display.
[0010] As a further description of the above technical solution: A sliding rod is fixedly connected to the upper rear side of the outer wall of the upright, and a slider is slidably connected to the middle of the outer wall of the sliding rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the quick-release mechanism is first fixed on the detection device. When pressure is applied downwards, the iron block will be squeezed inwards by the semi-circular groove. If the pressure is continued downwards, the iron block will be locked between the baffle and the semi-circular groove to achieve fixation. Then, the hollow column is pressed downwards. Since the iron rod is in a fixed state, the hollow column will drive the elliptical block to squeeze the spring downwards, so that it fits with the inner wall of the semi-circular groove. Then, the detection device is moved upwards to complete the quick disassembly.
[0014] 2. In this utility model, under the action of the spring, the clamping mechanism is in the unfolded state. Holding the first support rod pulls the rotating rod, and the rotating rod drives the second support rod to move inward, causing the outer shells one and two fixed on the first and second support rods to retract. Since the inner walls of the first and second outer shells are equipped with springs, when clamping an item, the inner walls of the two outer shells are squeezed, and the fixing plate two fixed inside the outer shell squeezes the fixing column. The fixing column squeezes the spring, which is installed on the inner wall of the hollow column two. The compression generates elastic force to achieve a stable clamping of the item.

A slider 10 is slidably connected to the middle of the outer wall of slider 17. A telescopic rod 9 is fixedly connected to the bottom wall of slider 10.

Sliding rod 17 provides a sliding track, slider 10 is responsible for sliding, telescopic rod 9 is responsible for telescopic extension, and suction cup 8 is responsible for adsorption. Specifically, under the action of spring 303, clamping mechanism 3 is in an unfolded state. Holding support rod 1 301 and pulling support rod 312, support rod 312 drives support rod 2 304 to move inward, thereby causing outer shell 1 305 and outer shell 2 306 fixed on support rod 1 301 and support rod 2 304 to retract. Spring 4 309 is provided inside outer shell 1 305 and outer shell 2 306, so the inner walls of outer shell 1 305 and outer shell 2 306 will be squeezed during the clamping process. Then, fixing plate 2 311 fixed inside outer shell 1 305 and outer shell 2 306 squeezes fixing column 310, and fixing column 310 squeezes spring 4 309. Since spring 4 309 is installed on the inner wall of hollow column 2 308, the compressed spring forms elastic force to achieve clamping of the item. Slide rod 2 17 provides a sliding track, slider 2 10 is responsible for sliding, telescopic rod 9 undertakes the telescopic function, and suction cup 8 is responsible for adsorption.
[0021] Working principle: First, fix the quick-release mechanism 2 on the detection device 12, then press down. The iron block 211 will be squeezed inward by the semi-circular groove 207 and press the spring 210 inward. Continuing downward, the iron block 211 will be locked between the baffle 206 and the semi-circular groove 207 to achieve fixation. Then press down the hollow column 201. Because the iron rod 203 is fixed, the hollow column 201 will bring the elliptical block 202 down to squeeze the spring 205 and fit into the inner wall of the semi-circular groove 207, thereby moving the detection device 12 upward to complete the quick disassembly. Under the action of spring 303, clamping mechanism 3 is in the unfolded state. Hold support rod 1 301 and pull grip rod 312. Grip rod 312 drives support rod 2 304 to move inward, causing outer shell 1 305 and outer shell 2 306 fixed on support rod 1 301 and support rod 2 304 to retract. Since outer shell 1 305 and outer shell 2 306 are equipped with spring 4 309 inside, they will squeeze the inner wall of outer shell 1 305 and outer shell 2 306 when clamping. Then, fixing plate 2 311 fixed inside outer shell 1 305 and outer shell 2 306 squeezes fixing column 310. Fixing column 310 will squeeze spring 4 309. Spring 4 309 is installed on the inner wall of hollow column 2 308 and compresses the spring to form elastic force to clamp the item.
