Sjaak shared some tips when sending PCBs to the fab house:
I usually collect a few PCB designs before sending them off to the PCB fabhouse. I prefer to use dirtypcbs.com as I know Ian from dangerousprototypes.com for a long time and think he provides good quality, and fast turn around time for your money. Also tend to be loyal to my suppliers so a better alternative may exist. The main reason I wait before sending them off is that I want my PCBs returned quickly. DirtyPCBs provide fast DHL shipping (about 2-3 days to .nl) but it is quite expensive (about 30 USD) compared to the manufacturing the PCBs. Luckily the PCBs don’t weight a ton, and adding more designs will not add much additional shipping costs.
