A CNC machine is used to process drilling, milling and cutting.CNC milling machines are already used in the PCB manufacturing process to route, or cut, around the board outline. The milling can also be used to remove copper from the surface of a circuit board in a process known as isolation milling. The milling will remove areas of copper on the surface of a copper covered substrate in order to create standard circuit board features such as pads, traces, fills, and vias.
Once completed, you will have a hardware prototype to work with.As a PCB designer, you produce manufacturing data for CNC prototyping. Prior to CNC prototyping, a circuit board would either have to be bread boarded, etched in-house, or sent out to a manufacturer: CNC machining is a booming sector of the manufacturing field. Across the nation, the Bureau of Labor Statistics expects nearly 8,000 machinist jobs to open up to prospective workers by 2026.
