PCB drilling is a key process in the whole printed circuit board production process.Drilling processing takes up the longest production time, and its processing technology and manufacturing equipment level will directly affect the quality, performance and cost of PCB (the processing cost usually accounts for 30%~40% of the PCB board cost).The machining of PCB drilling is mostly by mechanical drilling and laser drilling.According to the comparison of equipment cost and processing efficiency, more than 90% of PCB drilling in the world adopts CNC mechanical drilling, and laser drilling only accounts for about 10%.So CNC machine drilling is the mainstream of PCB precision drilling.
PCB CNC drilling machine is based on CNC technology. Through the coordinated movement of X, Y and Z coordinates, the X and Y axes are controlled to move quickly and accurately to the drilling position. The Z-axis actuator carries out drilling operation to realize precision drilling processing.As the aperture of PCB becomes smaller and the number of holes becomes more and more, a higher requirement is put forward for the micro-aperture machining capability of NC drilling machine.
