Nylon brush strips are an ideal choice in the field of wide line manufacturing in PCB manufacturing, such as line width/line spacing > 200um (8mil), copper foil thickness ≥ 35um, and sometimes can be relaxed to > 150um (= 6mil) . Due to its particularly high resilience, the nylon strip brush will not damage the brush roller when the PCB board is warped or the drill bit is broken, and the brush roller will not be damaged if the operator makes mistakes such as forgetting to turn on the cooling water. Stabilize and brush the circuit board and brush roller. Next, Aoqun Brush Industry will introduce the role of nylon strip brushes in PCB manufacturing.

9. For flexible plate grinding, choose the following combination: 600# alumina and 1000# alumina.
