What do I do once I mill a pcb? Answered

Should i use an etchant after milling a pcb with a CNC ? I am trying to learn how to use CNC to engrave PCB.
Please help.


Milling (and drilling) is all you need to do, if you've done it right !

You only etch to remove the copper from the board. Since your CNC mill removed the copper between the traces you don't need to etch it.
