CNC Machine Precisely Mills a Printed Circuit Board (PCB) for ATmega2560 | Satisfying Micro-Routing

Watch this high-precision CNC micro-router carve out a custom printed circuit board (PCB) in stunning detail. The machine meticulously mills away copper to create the exact traces and pads needed for an ATmega2560 microcontroller — the same powerful chip used in the Arduino Mega.
This subtractive manufacturing process is commonly used for prototypes and low-volume boards. The smooth, accurate movements make it incredibly satisfying to watch.
