Intro: CNC - PCB Creation
The PCB prototypes can be easily made on CNC machine.
For this task I created a schematics in the OrCAD
(Cadence product for PCB design),
and then transferred the layout to the DXF file.
For engraving process I used ROLAND EGX-350 CNC machine.
Due to I used a few through hole components, the PCB size was not limited,
so I choose it according the enclosures that I have in my stock.
