3 small boards is usually about $30

That price only seems to be for the

"Engineering Student Special

This is our EE Student Special

You must register with a school/university email address to be able to order this special.

Any orders without a school email address will be rejected."

http://store.bayareacircuits.com/engineering-student-special/

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.

The Weekend Warrior looks appealing

"$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.

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


(this is all from memory, but its pretty close)

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.  :-)

I like your boards.  You are a lot smarter with additional silkscreen printing and copper pours than I am.  I hope I get to be that good sometime soon.

I've used Myro. Been happy with their boards, I think their quality is better than PCBCart.

I would say Myro has same level of quality as US made boards (PCBFabExpress) -- but without the expensive US pricing.

It's a few dollars more expensive than other China fabs, but not a deal breaker. I'll use them again when it's time to re-order.

Thanks! :-)  It just takes hours... and hours... of detailed work.  And a willingness to throw a design away and start over when the layout starts taking more effort than it should.  What works for me is to camp out on the couch in front of the TV with my S.O. and poke away on my laptop.  This set took me about a month, working for a few hours a night.  Not every night, but many of them.  I'm kind of OCD though.

Good to know.  The published prices look almost too good to be true, but that's probably just shock after paying $300 for the last batch. smiley-eek-blue  I had to click "Submit" with my eyes closed on that one.

I regularly order $300-$700 worth of boards.  My last order with Myro was $650 (for 100 boards, gold immersion pads and fingers, cutouts, routed shape, it's a big board). Still cheaper vs. US based companies. 

Myro is based from Canada, but their actual PCB fab is in China.

I just put in my first order at this place:

http://dorkbotpdx.org/wiki/pcb_order

They are supposed to come back from the fabricator in about a week.  Pretty good deal considering the fast turnaround and tight board specs.  It is also nice that I can just send them my eagle board file and they will take care of creating the gerber files from it.  Cost me about $14 for 3 double sided boards.

Well many thanks for all tips and help.
I dont know why pcb shows without pin 8 connected, since it's connected to gorund in the diagram view :o (maybe fritzing sucks)
I will try to do it single side only and will post diagram and pcb here so you can review it

@pwillard yes i'll use laser printer toner transfer method if i need some help i'll get in touch with you. thanks

why didnt fritzing connected it at pcb view ?
thanks

Is diptrace the program that is being discussed elsewhere in the forum, it bypasses some of the windows security settings as part of the installation?
They've commented in the EEVBlog forums that this was an inadvertent setting in their installer, and they've uploaded a corrected version.  FWIW.

You don't have that Gnd connected to the other grounds either.  How do you add a Ground plane?

RE Post # 26 Pin 8 is connected to the crystal loading capacitors.. Only there is no visible net label or a ground symbol. While the cad program (Fritzing) might connect the pin labeled ground on the IC to ground, the pin isn't labeled so you got exactly what you put down. If you label that net as ground and do a copper pour it will fix the issue.
