What is PCB ?

PCB is an interactive printed circuit board editor for the X11 window system with either a GTK interface (default) or a lesstif interface.
PCB includes a rats nest feature, Blind and Buried vias, and Design Rule Checking.
PCB offers high end features such as an autorouter, a topological router and a trace optimizer which can tremendously reduce layout time.
Plug-ins: compile separately and load at startup of pcb.
PCB includes exporters for:

- Batch: text line "batch" HID, which exists for scripting and non-GUI needs.
- Gerber: Industry standard RS-274-X and NC drill output.
- BOM: Bill of material and centroid data X-Y data output for use in the board fabrication and assembly process.
- PS: PS output.
- PNG: GIF, JPG and PNG graphic formats output.
- Nelma: Export output files for trace capacitance calculations.
- GSvit: Export output files for Finite Difference in Time Domain calculations (FDTD).
- IPC-D-356: Netlister with output conforming to the IPC-D-356 standard rev. 0.
