Hi there,

First time milling a pcb.

A situation I have gerber/exellon files for a pcb.
I already drilled the holes (exellon) and worked perfect.
the situation is how I remove the inner circle inside a pad to clear space for solder, from the gerber file (I dont need it as I already drilled the board right?)
I think this is a normal procedure when milling pcb's?

Thanks for your help


I am using a program called flatcam (FlatCAM: PCB Prototyping CAD/CAM) love it. Tried a lot of them.
