Drill process - China PCB manufacturing
Drilling is very critical to the PCB manufacturing process, holes of various sizes are drilled through a stack of working panels and the drilling process is computer numerical control.
Holes of various sizes are drilled through a stack of panels (usually 3 to 4 high). The locations are determined by the board’s designer to fit specific components. Drilled hole sizes are usually 8 mils larger than finished plated through hole sizes to allow for the copper plating process.
