Dirty PCBs detailed review by Big Mess o’ Wires:
Now for the key question: were the boards any good? From my inspection, I’d say mostly yes. I spent a long time examining the boards under 10x magnification, and comparing them to my original EAGLE files, and to the Gerbers using gerbv. Probably I’ve never examined any PCB quite so intensely, and some of the issues mentioned below may be typical of other discount PCB manufacturers too. For the money paid, I’m not complaining, but for completeness I’ve catalogued the good and the not-so-good.
