Why should circuits have all the fun when it comes to free design software? Where is the love for PCBs -- and the free software tools for design and editing? The answer is they do, in the form of FreePCB, which allows users to design and edit PCB schematics using a simple graphical interface. The interface won’t win any awards for the 2D graphics themselves, however its ‘beauty’ lies in its functionality. Users are able to design PCBs with up to 16 copper layers at a maximum size of 60 X 60-inches! To put that into perspective, that’s a 5-foot square motherboard! The software suite provides the all the tools needed for PCB layouts, including English and metric functions, Ivex Design International, PCB Matrix and IPC libraries. FreePCB also comes with Footprint Wizard/Footprint Editor
for footprint design and editing, design rule checker and the ability to import and export PADS-PCB netlists. The software is designed to work under Windows, however it can run on Mac and Linux-based systems using Virtual Box or Wine through the MacPorts application.
