[0002] In the manufacturing process of PCB (printed circuit board), roller brush grinding is a key step that directly affects the surface quality of the circuit board and subsequent processes. In the traditional roller brush grinding process, factors such as roller brush material and uneven pressure distribution may lead to poor grinding effect.

[0003] At present, scouring pads are used for PCB roller brush polishing due to their good wear resistance, softness and adaptability. By putting the scouring pad on the outer surface of the roller shaft and polishing by the contact between the scouring pad and the PCB surface, the polishing effect can be improved.

[0004] However, when using the above method to polish the PCB with a scouring pad, there is a lack of detection of the usage status of the scouring pad.
