Discusses PWB manufacturing. Requirements can be divided into two classes: prototype and production quantities. Prototype boards have traditionally been constructed using a photographic etching process, although milling is becoming popular for single-layer prototypes due to the fast turn-around time and reduced setup costs. Production quantities are seldom milled due to a large processing time per board and are more often etched or deposited.
