PCB Manufacturing

A simple, quickly to learn, free open source CAD software for manufacturing of PCBs is KiCAD provided by the University of Grenoble:

The prototyping PCB of the "Stuttgarter Geigerle was developed using this software. The archive provided for download also contains the Gerber files (.pho) and the drill file that can directly be used to manufacture the PCB. The layout can also be printed to a transparency foil with an inkjet printer. The foil can be used as a mask for exposure of a copper laminated pcb covered with photosensitive lacquer. However the prototyping board contains additional footprints for SMA connectors and resistoors for testing purposes. These are also visible in the KiCAD circuit diagram.
