It is one of the important components of the electronics industry, providing mechanical support for the fixation and assembly of various electronic components such as integrated circuits, realizing the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and providing the required electrical characteristics, such as characteristic impedance, etc. Common electronic equipment, from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are integrated circuit electronic components, must use printed circuit boards for the electrical interconnection between them.
[0003] When the circuit board is processed and produced, various electronic components are soldered on the circuit board to electrically connect the electronic components, and then the circuit board is fixedly installed in the inner cavity of the shell to assemble the circuit board, and the shell protects the circuit board. When the circuit board and the shell are assembled, the circuit board is placed in the inner cavity of the shell, and then the worker manually moves the circuit board to adjust the position of the circuit board so that the through holes on the circuit board are aligned with the mounting holes on the inner wall of the shell, and an electric screwdriver is used to thread the mounting bolts with the inner walls of the mounting holes. The bolts squeeze and fix the circuit board to fix the circuit board and the circuit board and the shell. When the through holes of the circuit board and the mounting holes of the shell are aligned, the worker needs to manually adjust the circuit board, which increases the difficulty of assembling the circuit board. When the electric screwdriver is used to fix the bolts with the knobs, it is easy to cause the circuit board to vibrate, causing the positions of the through holes of the circuit board and the mounting holes of the shell to be offset, reducing the stability of the circuit board assembly and making it inconvenient to assemble the circuit board and the shell.
