Free PCB Layout Software
Looking for free PCB layout software? Check out PCB Artist which is offered by a company called Advanced Circuits. I use them for all of my prototype circuit boards. They have a great $33 board option (minimum qty. 4), but they also have a less expensive "bare bones" option when you need to bang out a quick inexpensive PCB.
The PCB Artist software lets you draw schematics and lay out PCBs using a large library of components. But it also gives the option of designing your own part symbols and footprints. There is also design rule cheking and design for manufacture checking to help ensure that your board is ready for manufacture.
Is there a catch? Well, a small one. When your design is ready, the files must be uploaded to Advanced Circuits, so they are guaranteed to get the first order. But that's a small price to pay for something you want anyway. And the software is free. Here's the link:
