I just finished up my order for the circuit boards for my EFIS and FMC panels. Let the waiting begin.
There are two pcb in my EFIS build, one to mount the PB switches (6x6 with led) and one to mount the rotary switches and the interface headers. There will also be a waterfall cable between the boards.
The FMC pcb is one big happy crowed board that holds all 69 (6x6 with led) switches plus a mounting hole for the brightness encoder.
I use JCLPCB.COM for my pcb vendor.
