I am trying to find a free/low cost PCB design software that I can use for my projects (PCB = Printed Circuit Board; some prefer PWB, Printed Wiring Board). It needs to be able to support at least 8 layer boards, with no limitations (such as limited pin count/board size) and has to be able to export my design as a Gerber file.
I've tried ExpressPCB, which I really like, but they only support up to 4 layers, where the 2 inner layers are only for power and ground. I've also tried FreePCB, but you can't directly attach pads to copper areas, which I need to be able to do.
So basically I'm looking for something similar to ExpressPCB, but with support for more layers and a Gerber exporter. It would be nice if the software was free, but the most I'm willing to pay is $50. Any ideas?
