PCB123

Why do I keep using the PCB123 software? It is simply top-drawer for a freeware to develop the circuit boards. It works just as needed and is able to alert you if you have traces that cross and should not cross, traces too close to other things as well as unconnected components. It has design rules that make the boards high quality and PCB123's manufacturing is top-quality. They turn out to cost about 50% more than their competitors for low volume production runs. I choose to author in this software and copy my layouts to the other CAD software for obtaining lower cost PCB products. This process does have its drawbacks in that the design may be perfect in PCB123 CAD but redrawing it may cause an inadvertent short as in my first prototype board.
