Introduction
- Example of CNC Circuit Milling on a Commercial CNC Circuit Mill
- As you can see, the milling bit rotates at very high speeds (thousands of complete rotations per minute, aka "revolutions per minute" or just "rpm") and removes material from the top layer (and a bit of the bottom layer) of the circuit board.
- The circuit board is comprised of a thin top layer of conductive material (often copper) that is adhered to a layer of insulating material below.
- During milling, the insulating layer provides a safety gap between the milling bit and the precision work surface (which should not be marred).
- Once the milling is complete, the remaining copper traces form the actual conductive circuit (without the components soldered yet), while the relatively intact insulating layer gives the circuit board its rigidity.
