Depends a lot of PCB manufacturer and how good is the registration of the films to drills and what is drill precision etc. General rule is that components are placed on the copper layer pads, so copper fiducial is aligned with same accuracy as the pa

I need some PCB Drills, any suggestion on this?

Have you taken the plating thickness into consideration as this will happen after the drilling?

why wouldn't you just drill one larger hole?

Assuming, you have nothing on the other board side, I would drill a hole through the trace and board with a step drill and a drill press. If you adjust the depth control carefully the wider step of the drill scratches the surfaces of the trace to mak

I need to change Drill holes sizes in a PCB from 0.6mm to 0.55mm. Do it need to change anything else other than the Drill hole size in the INfo section of the Gerber file, for example do i also need to change the artwork of the other layers if the dr

IPC 2221B mentions a minimum clearance of 0.5 mm between adjacent holes. A drill-to-drill spacing of 20 mils is a standard value in manufacturer design rules. For small annular rings and pad-to-pad clearance, the minimum via distance is often defin

Proper fiducials are going to be more accurate than drill holes. Since drilling is a separate step in the PCB fab process, the registration to the PCB isn't as accurate as the copper etching process which forms the fiducials. In a pinch, it can be u
