Here I must praise KiCad. It is one of the best pieces of FOSS software out there. It beats almost all other (commercial or non-commercial) software in PCB design, hands down.

Same, compared to some other free alternatives (for example CircuitMaker) it's a complete blessing. I think I haven't seen a worse piece of software then CircuitMaker.
