[0002] Printed circuit board (PCB) slotting refers to cutting a series of notches or grooves on the circuit board during the PCB manufacturing process to meet specific design requirements. After slotting is completed, the PCB is taken out of the device, and visual inspection or automatic detection is required to ensure that the slotting quality and position accuracy meet the requirements. When multiple circuit boards are connected, they need to be docked at the cut slots. How to accurately dock the slots requires the use of a positioning structure.
