Cedar Rapids, Iowa | I do some PCB design using software called Eagle PCB.
If you are using a relay, that means you're either concerned with voltage isolation or high amperage. In either case, there are specific rules about how to handle those cases on a PCB. High voltage needs distance between the traces. Amperage needs large traces that can handle the amperage with sufficient heat dissipation from the board.
For PCB manufacturing in the US, I'd recommend OSH Park. Most of their business is fast production of PCBs for prototyping. Typically you pay $5 per square inch of your design and they'll mail you three copies of your board to test. Turn around time is about 2 weeks. Once you like the design, they also offer larger production at $1 per square inch.
Then you have to populate the board and solder in the components. I don't know who does this in the US. | |
