Size and quantity of the PCB hole
The PCB cost of the hold drilling is mainly depended on the hole
diameter, drilling speed and error value. In the process of the PCB
Board hole drilling, it will take a higher cost when the hole is
smaller. And we suggest the hole size should be no less than
0.3mm.In addition, as for the aperture ratio, our suggestion is
between 1/6 to 1/5. Because the PCB hole will be damage if the
aperture ratio less than 1/8, which will increase the scrap rate.
In the meanwhile, the more drilling hole in the PCBs, the higher
cost will be taken place.
