Low Cost PCB Mill - Massachusetts Institute of Technology

The Challenge: Design a low cost circuit board milling machine optimized to be mass-produced. Technical Approach: Several observations on the process of circuit board milling serve as the premise of the design: X and Y resolution of 0.001" is sufficient. X and Y positional accuracy and repeatability is important for creating thinly spaced traces.
