Free circuit board layout tool PCB 3.0


PCB version 3.0 printed circuit board layout tool

pcb is free software for designing printed circuit board layouts. It has many features and is capable of professional-quality output. It is available for UN*X operating systems, e.g., GNU/Linux, Mac OS-X, or Cygwin under Windows. pcb was orignally written by Thomas Nau of the University of Ulm, Germany, and is now maintained by harry eaton of the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, USA.
PCB 3.0 is a branch of the source code modified to operate under the Tcl/Tk interpreter. Most of the coding for PCB 3.0 was done at MultiGiG, Inc., Scotts Valley, California, by Tim Edwards, Paramesh Santanam, and (working from India, courtesy of SynApps, Inc.), Nishit Patel. The code base is a departure from the original PCB in that a complete Tcl command-line API was concocted for PCB, and the GUI re-written as a Tk script. For the first cut (version 3.0), a fair bit of effort went to ensuring that the GUI looks and acts as much like the original Xlib-based version.

    Over the last few months, I’ve been waihctng this site come online and noticed several interesting additions. I look forward to participating in your online community for pcb designers and look forward to reading more helpful and intriguing information for people like me who avid pcb engineers. There is nothing worse than searching through endless blah blah blogs just to locate a few that keep ones attention. Thanks. Great work!
