Henk, A couple of options, one I know, one I don't yet: Cadsoft (www.cadsoft.de or www.cadsoftusa.com) has a nice PCB CAD tool (Eagle CAD). There's a freeware version, but it's limited in schematic and PCB size. There's also a low cost non-profit version that's still somewhat limited but a lot less, it might work for you. I've been using an older version for some time now, it's quite a nice product. There's also www.pcb123.com, which is a PCB shop that offers a freeware PCB tool to go with their service. I think the trick is that it's tied to their PCB fab, but their prices don't seem to be fairly reasonable. I haven't tried that yet. That one doesn't seem to have any size limits. paul
