[0002] An integrated circuit is a miniature electronic device or component. During its production process, its circuit chip needs to be soldered. In order to ensure the accuracy of soldering and prevent soldering errors, the circuit board is usually fixed by a clamping mechanism to prevent it from loosening.

[0003] According to a patent application published on the patent website, a clamping device for integrated circuit production (authorization publication number: CN 218499357U) describes a device that "enables workers to flip integrated circuits without touching them by providing a worm, a worm gear, a rotating shaft, and a first return frame. The device also utilizes the self-locking properties of the worm gear to maintain relative stability. Furthermore, a second return frame and bolts are provided to adjust the position of the second return frame according to the size of the integrated circuit board."

However, when people cannot touch the circuit board, a robotic arm is required to remove the circuit board. When the circuit board is welded, the top and bottom are restricted by the clamping plate and the fixing block, and the side is limited by the return frame. Due to the obstruction and restriction, it is difficult to remove the circuit board through the robotic arm, and disassembly is inconvenient.
