Hi, I think the hole wall will be covered with copper anyway, maybe making a short circuit between layers.
There are 2 ways: 1. Tell the pcb maker which holes will be not plated. 2. If you send the gerbers to an automatic pcb maker, such as pcbexpress, let them fill the hole and afterwards you can sand it with an abrasive file. And, as Abhijit says, with zero annular rings. Both ways have worked for us. Pedro. > right clock on pad and go to pad edit. uncheck both the coper and component side. Hoping it may solve your problem. > > Abhijit > >
