Processing Gerber files for manufacturing printed circuit boards

The development of electronic prototypes requires the manufacture of printed circuit boards (PCBs), which its role is the support and the interconnection of electronic devices. PCBs became of vital importance when the complexity of prototypes requires the connection of a large number of components. This paper presents a technique for manufacturing of PCBs by milling machines, which is intended to reduce the time of the manufacturing process. The approach used in this work is based on image processing algorithms (dilation, erotion, and coding) and a microcontroller circuit. The results are promising, because the time required to perform the PCB is less than with other techniques used by the hobbyst.
