After my initial PCB success with Maker Studio, I uploaded the design files to three more board houses. I had planned to try four or five more, but I started to get the impression that many of the China-based sources used the same fab house, so I stopped at three.
Elecrow‘s basic board fab service supplies 5 or 10 PCBs for $11.90, with a basic international shipping cost of around $7 for 5 boards. Although I haven’t been paying close attention to delivery time for these reviews (too many variables), I will say that Elecrow was significantly slower than the other three sources.
Several board thicknesses and surface finishes are available, but only green soldermask. Maximum board size is 10cm × 10cm. 6/6 rules are supported, though they “recommend” 8/8 (trace width in mils/space width in mils).
