PCB drilling machine is a machine used in the drilling process of PCB processing.
PCBs must be drilled with holes in the board to allow the pins of the components to be plugged in before the components can be plugged in or to make the various levels of the circuits turn on and off (VIA).
With the increasing integration of the PCB board, the aperture requirements more and more "small", and now the aperture at 0.1mm level
