Free PCB
http://www.freepcb.com/


FreePCB is a free, open-source printed circuit board layout editor for Microsoft Windows, released under the GNU General Public License. It is not quite finished, lacking some important features such as a Footprint Editor, Design Rule Check and Autorouter. However, it is quite capable of laying out a PCB and producing Gerber files. Some of its features are:
- 1 to 8 copper layers
- Board size up to 60 inches by 60 inches
- Footprint libraries courtesy of Ivex Design International Inc.
- Copper fill areas
- Imports PADS-PCB netlists
- Exports extended Gerber files (RS274X) and Excellon drill files
If you use FreePCB to design a PCB, I would STRONGLY suggest that you check your Gerber files with a program such as ViewMate (available for free here) before spending any money to have the boards manufactured.

Merlin PCB designer

The Merlin PCB designer package
Probably you are professionally involved with printed circuit manufacturing and you are looking for a cheap, easy to use package to design printed circuit boards (PCBs).
Or maybe you are just making a few PCBs for your job or at home, and even a non-commercial version of a standard PCB layout software would constitute a significant part of your monthly expenses.
In either case, you may have found that PCB design packages tend to be rather expensive and complicated pieces of software. But you already have a nice graphics program, like CorelDRAW, on your computer, and you wonder why you could not use it for designing PCB layouts. In fact, you can. Merlin PCB designer is a shareware solution that offers you the possibility to do just that.
Available on the net is a zip file containing CorelDRAW files (from version 7 on), and a large component library + manual.

عفوا .....ما معنى صحيت هلبــــــــــــــــــــــــة
وضح لى المعنى ( يا مقصوف الرقبة :giggle: بهزر طبعا مش جد )
اوعى تزعل يا أخى لأنى بهزر معاك
و لا تقل المعنى فى بطن الشاعر
