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.
