3 small boards is usually about $30


That price only seems to be for the

I don't see a way to get 3 boards for $30 elsewhere.

I suppose I could game the system and order thru my college alumni address, and set up another paypal account with the same address- but my ship-to address would be a giveaway as it's in a different state.

"$125 Gets you

?1 PCB Design
?As many of the design that will fit in 90 square inches"

A 3.4" x 2.25" board is 7.65 in^2
So I could get 10-11 boards for $125 in 7 days with USPS shipping included.

For comparison:
Same 10 boards from iteadstudio (2 layer <10cm x 10cm) are $24.90 + $25-30 for fast DHL shipping.

It's not the online deal, it's a deal the system gives you when you make the board in DipTrace, check design rules, etc., and submit it directly through DipTrace.  They don't even list it as a deal, but whatever pricing schedule they are using beats the online price always, as far as I have seen so far.  The price depends on the dimensions and particulars for the board.  Here is my invoice.  This is a very small board with a QTFP-100, two PLCC-32 sockets, a crystal, a few resistors and caps, and two connectors (programming - 10 pin and output - 16 pin)



Once you have your design, you just go to File > Order PCBs and you get this dialog:



I sent this to them last Monday afternoon.  They shipped it today.   The last once I did (my first PCB ever) was very nice and worked great.
I have only come here seeking knowledge. Things they would not teach me of in college.

One other thing, I totally am going to try out iteadstudio.  I recognize they have great prices.  But these are my first boards and they are experimental so getting 3 instead of 10 isn't a big deal for me.  Being able to order out of the program rather than trying to make sure I have sent all the correct files is a big plus to me.  I recognize that am paying for convenience and lack of experience here.

For itead:
http://imall.iteadstudio.com/open-pcb/pcb-prototyping/im120418003.html
Go here, scroll down, and click Download.
Download & unzip the files for Eagle.
Put the .dru file in the eagle /DRU folder, and .cam in the /CAM folder.
(.drc file? I don't remember)

When your design is created, and you're satisfied with the error rule check (ERC) on the schematic,
and you're happy with the board design,
use the .dru file for the design rule checks on the .brd file. Fix any errors.
There are usually a bunch of Stop Mask errors, especially if you have any headers. I usually ignore them if I am satisfied with the markings presented.
(You can right-click & SMASH components, then move names around, resize them, etc. If you get too confused, Unsmash & start over with a fresh Smash. Really helpful if you delete a name by accident)

When satisfied, create the gerbers. From the .brd file, its a 2-step process.
(this reads more complex than it is)
File:CAM processor, new message box opens
File:Open:Job:select the itead .cam file
then click Process Job. Bunch of files get created, 13 total.
You can download a free viewer from viewplot.com to check them out.
When satisfied, put the 13 created files (but not your .sch and .brd files) in a zip file, that's you send to itead.

Order PCBs, you'll get a Order #  back.
Send the Order # and your zip file to pcb@iteadstudio.com

Somebody in another forum suggested MyRO as a fab house.  Any experience here?  I really, really like the boards I get from ExpressPCB.  I also like the software and the "just do it" built-in ordering.  The price is ridiculous though, so I'm evaluating services that can produce top-notch boards, quickly (I'm impatient), for a little less than an arm and leg.  Being able to route inside the perimeter would be nice, too.

My humble opinion to the OP:  I would highly suggest you use a more capable design app, and clean up the traces a little.  Try and keep as much space as possible between any two traces, and any pads.  There are several of your traces that skirt right up to other elements, when there's plenty of open area that you could be using.

Here's my latest project -- maybe it can provide some inspiration.  Or maybe I just swapping project photos with people.  :-)
