Milled PCBs

     •Historically, this is the method that has been used the most in this course.
     •An X-Y stage is used to guide a router bit along the contours of the PCB traces.

     •The result is a copper-foil that has a minimum of copper removed in order to form the connections.
     •The “backplane” that is left on the board can actually be useful for noise control if it is connected to ground appropriately.
     •Advantages: chemical free, quick, in-house (cost)
     •Disadvantages: no plate-through holes, usually single-sided
