Instead of 30? No, it typically costs a lot to do one-off pcbs. Even through a batching service (where you share a large panel with other people), they'll still usually make you pay for a few of them. Also, all of the components are going to cost way more if you just want to buy one of each. Headers are tenths of a cent per pin but from digikey you'll probably have to buy a strip for a dollar or so. Likewise with crystals, vregs and caps.

OSH Park (probably the most well-known such service) costs $10/square inch for a 4-layer board, for three copies of a board.

As a ballpark figure, this board should be no larger than 1/5 square inch, so that's $2, for three boards.

Agree on low volumes of the other components, although things like Seeed Studio's Open Parts Library (http://www.seeedstudio.com/depot/OPLopen-parts-library-catal...) is pretty nice for the very basics.

Update: Didn't check if this board meets OSH Park's limitations.

In general you can't really do bga with osh park without fudging their specs significantly. Some have been able to do it but you tend to end up with peeling traces. Also, don't forget shipping on all the bits and pieces.

its 4 layer PCB with 275 micron via pad and 75 micron mechanical drill. I am not joking our PCB fab confirmed its doable technology for them.

I think many PCB fabs will say they can do it, the question is how much they will charge. 75 micron drill is crazy.

PCB confirmed the "DIPSY easysolder PCB" deliver on 20th july, this is special downgraded version of the PCB, 2 layers, drill 0.15, trace space 50 micron..
