Printed circuit board milling is the process of removing areas of copper from a sheet of printed circuit board material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file. Similar to the more common and well known chemical PCB etch process, the PCB milling process is subtractive: material is removed to create the electrical isolation and ground planes required. However, unlike the chemical etch process, PCB milling is typically a non-chemical process and as such it can be completed in a typical office or lab environment without exposure to hazardous chemicals. High quality circuit boards can be produced using either process. In the case of PCB milling, the quality of a circuit board is chiefly determined by the system's true, or weighted, milling accuracy and control as well as the condition (sharpness, temper) of the milling bits and their respective feed/rotational speeds. By contrast, in the chemical etch process, the quality of a circuit board depends on the accuracy and/or quality of the photomasking and the state of the etching chemicals.

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 of the circuit board.
  • The circuit board is comprised of a thin layer of conductive material (often copper) that is adhered to the top of a layer of insulating material.
  • Once the milling is complete, the remaining copper traces are the finished circuit, while the adhered insulating material forms the rigid structure of the circuit board.
