ZenitPCB Layout is entirely freeware for personal or semi-professional use, limited to 800 pins, that is borderline between the hobby and professional jobs.

24. Open Circuit Design

Open Circuit Design provides 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 initially written by Thomas Nau 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 codebase is a departure from the original PCB in that a complete Tcl command-line API was concocted for PCB, and the GUI was re-written as a Tk script. For the first cut (version 3.0), a fair bit of effort ensured that the GUI looks and acts as much as the original Xlib-based version.

Limitations:

• Windows operating Only
• layers: 8

25. gEDA

• 3D Viewer

KiCad includes a 3D viewer, which you can use to inspect your design on an interactive canvas. You can rotate and pan around to inspect details that are difficult to inspect on a 2D view. Multiple rendering options allow you to modify the board's aesthetic appearance or hide and show features for easier inspection.

29. Eagle

EAGLE is a scriptable electronic design automation application with schematic capture, printed circuit board layout, auto-router, and computer-aided manufacturing features. EAGLE stands for Easily Applicable Graphical Layout Editor and is developed by CadSoft Computer GmbH. Autodesk Inc. acquired Cadsoft Computer GmbH in 2016.

EAGLE contains a schematic editor for designing circuit diagrams. Parts can be placed on many sheets and connected through ports.

The PCB layout editor allows back annotation to the schematic and auto-routing to connect traces based on the connections defined in the schematic.

EAGLE saves Gerber and PostScript layout files and Excellon and Sieb & Meyer drill files. Many PCB fabrication companies accept these standard files.

Features:

• Schematic Editor

The schematic editor allows you to create a symbolic easy-to-read representation of your design.

• Layout Editor

The layout editor brings your design to life.
The board represents the physical reality of your design.

• Pros and Cons:

Pros: Eagle CAD is easy for hobbyists just starting with printed circuit CAD designs and includes free options for limited tool versions.

Cons: This software is not mainstream with corporate businesses that have internal PCB designers. Also, using this tool for higher technology boards requires more manual calculations and routing than the higher-end CAD tools.
