This is a free computer-aided design (CAD) software program designed for beginners or students. This program allows you to create schematic drawings via the ExpressSCH tool. You can use it to add components and pins, and connect these objects together via wires. A schematic drawing will help you create your PCB board. The program features a drag-and-drop feature, which allows you to select a component from the components library, add it to the drawing and drag it into place. You can also link your schematic drawing with the PCB board. The ExpressPCB program is compatible with Windows XP, Vista and Windows 7, and you can download the program from the author's website. While the program is free, you must pay for the actual boards, which start at $51 for three boards.
DipTrace
This program allows you to create both schematic drawings and PCB boards, and you can import data from or export data to other electronic design automation (EDA) tools. You can also exchange items from your components library, and the DipTrace library comes with over 100,000 component parts. You can also create your own footprints or parts using the component and pattern editor. You can create a 300-pin circuit board using the freeware version of this software program. There is also a shareware version, which means that you can use this program 30 days for free. After that time period is over, you must purchase the program, which costs between $75 and $695, depending on the version of the program.
PCB123
The PCB123 Design Software program is a free program designed for industry professionals, especially the manufacturing industry. This program, which uses a CAD interface, allows you to layout and design PCB boards and schematics, and it automatically updates both the PCB schematic and layout when you make a change to one or the other of these designs. This program also features a wizard to help you layout your first board, and you can import items to or export items from other programs. The PCB123 Design Software program also allows you to preview your designs in 3D, which means that you can see your designs from multiple angles.
