PCB make+assemble service

Hello,

I'm looking for a service that could manufacture 200+ double sided PCB's and solder the SMD components (both sides) in place.

What's the cheapest?

Where are you located? What is the size and complexity of the boards? Do they need to be surface mount? If so, how many and what size components? Do you want solder paste & silkscreen? 1-side, 2 sides? Do you want them electrically tested for continiuty or shorts? All of them? Some percentage of them?

Where are you located?

Between the weed and strippers
(the netherlands)

What is the size and complexity of the boards?

22mmx13mm
don’t know the complexity, look for yourself:

Do they need to be surface mount?
If so, how many and what size components?

Component list:
-QFN32 SMD IC
-MIC5205
-2x 10uF (1206)
-4x 0.1uF(0603) (from which 2 are mounted on the bottom)
-2x 10K (0603)
-1x 330 Ohm (0603)
-One of those tiny 16Mhz 3 pad crystals with built in 22pF caps.
You might have already guessed it but it’s a arduino clone based on the Pro Mini

Do you want solder paste & silkscreen? 1-side, 2 sides?

Yes. The components are all SMD and most of them are at the top, some at the bottom.

Do you want them electrically tested for continiuty or shorts? All of them? Some percentage of them?

Yes, at least a couple need to be tested, not a lot.

Will look when I get home, can't open from here...

"Between the weed and strippers"

Had to think about that a while 8) I'm thinking you are referring to Amsterdam.

Good guess! Actually meant Holland , not specifically Amsterdam. I can drive to Amsterdam in 30 mins. though.

Yes, but I didn't know how pervasive the 'culture' was. I've only been to one of the coastal towns, in offseason for an electronics convention, and didn't see any of that.

I've also actually never seen the "rode ruiten"(=red windows) in Amsterdam.

Been shopping for electronics parts there though. It sucks Holland doesn't have a lot of stores like Radioshack etc. And when we order something from Mouser shipping is more than $26!

Is stuff expensive from Farnell.com, Newark.com also?

4.85 euro for a '328 chip - yes, I guess it is! http://nl.farnell.com/atmel/atmega328-pu/mcu-8bit-avr-32k-flash-28pdip/dp/1972087

Yes, the components are more expensive then mouser and shipping even worse.

I hate the fact that mouser has a NL domain with components more expensive then the .com while they come from the same warehouse...

Well, if you have the gerbers & a PL, I bet you could have a place like iteadstudio.com quote building those for you. It's a good qty, more than I'd want to hand assemble. Probably still get hosed on VAT tax.

If you can move all the components on one side of the board, you should be able to do your own skillet reflow soldering. I do it all the time. Last project I did was 350 tiny boards. Took the better part of a week, but it wasn’t too hard. Like I said, to make it easy, you want all the parts on the same side of the board.

Not using any specific parts, just general/generic ones, the individual cost if purchased through Digi Key would be around $3.62 $3.85. With PCB service through ITeadStudio, add another 25 cents each. And I would strongly suggest getting stencils made … $25 for 6-up on a single 8.5 x 11 sheet.

I should note, the pricing I looked at were for bulk purchases of 250, 500, and 1,000 pieces. In some cases it’s cheaper to purchase 1,000 of something than it is to buy 800.

Your design doesn’t seem to have an ISP header broken out (or if it does, it’s not in the standard 2x3 configuration). You’re going to need that to put a bootloader on the board (if you’re planning to run Arduino on it), or to burn sketches directly to the board. Might also be worth it to break out the FTDI pins if you haven’t already.

As CR mentioned, chances are you will get nailed with VAT when you get them. But, if you think you’ll be ok, and you want to provide parts (or the money to procure them), I’m happy to cook them for you with the only requirement that you move the parts top-side only.

Since i'm a student and i'm busy with school a lot i can't spend that much time. I am making an arduino based reflow oven controller for the first prototype batch (about 10 boards).

Nope, ISP is not broken out but i'm planning on making a simple board that has all the pins broken out to standard 2.54mm header pins and that adds ISP header. FTDI pins are already broken out though.

If you'd like, and are willing to share your design, I can attempt to re-route them to the top layer. But that's entirely up to you and would of course depend on whether you want to do that and/or want to figure out if it is worth the cost to have them outsourced, or if you want to do them yourself.

KirAsh4: If you'd like, and are willing to share your design, I can attempt to re-route them to the top layer.

No, i'm sorry. I had to add another part (to the top layer) so it's really tightly packed right now. I also already did all the silkscreen things and i don't want to do it again. Thanks anyways.

Ah, from seeing the board design you posted earlier, I recon you could potentially use smaller pad sizes along the edged if you’re going to have through holes anyway. That should buy you some more real estate. And you could also always shrink thins down even more by using 0402 parts. But that’s now nitpicking. :slight_smile:

You could still build a reflow-friendly board by having the smallest, or hardest parts on one side of the board (such as the ATMega, regulator, small 0603 parts, and the crystal) and move the large 1206 caps on the other side. Those are easy to hand solder.

Have you decided what you’re going to do as far as production of the quantity that you want?

Hm.. I'm not that good at it, its also already routed, could i send the .brd file to you?

I'm going to have a fundraiser and see how much are wanted, minimum number i think about 200-250. If you could get the parts to the top i think i will try to let you assemble them if you want to do it.

You'd have to send both files. Zip up the .sch and .brd files together and send that. If you want to do that, I'll send you a PM with my e-mail.

We'll have to talk timing, as in what your deadline is, and how to procure all the parts. But if things work out, then sure, I'm happy to help.

Okay thanks, you can PM me
