The standard service is $14 for 10 boards. You can have the pads ENIG finished for $15 more, which brings the total cost to $29 for 10 boards, shipped. It is still an excellent deal. The quality is excellent too, as the closeups below illustrate.
|Fig 1: The pads for this 0.5mm pitch QFN were solder mask defined in the design.|
|Fig 2: Actual solder mask on the PCB. They expanded the clearance here by quite a bit, but this is perfectly reasonable.|
|Fig 3: Tigher clearances here on this side.|
|Fig 4: 0.1 inch header - Drilled holes alignment are quite good.|
|Fig 5: 1mm pitch Flat-flex connector pads.|
|Fig 6: Pads for 0603s. To the right is a 2mm pitch, two-pin header.|
