OT: PCB Assembly service in europe

[Sylvain Munaut]

Hello,

I'm looking for a PCB assembly service in europe (and pcb fab if possible,
if not I can have the pcb made elsewhere). I don't have a complete BOM yet
but I already know that my board will be max 1 dm square, 6 layers.
The most complex component is a 256 pins BGA with 1mmpitch and TSOP 66 DDR
chips. I'd say max 1000 smd pads.

I need a series of about 15 PCBs but if only the SMDs are soldered it's fine,
I can do the rest (thru all, big connectors, ...) by hand.

Any one know where I can have this done and for about which price ?


Thanks,

Sylvain

These people (UK) are very good for SMD assembly:

You really need to discuss the board with your assembler before finalising
the layout - things like fiducials need to be acceptable to them.

They can just mount the 'dificult' chips for you, it won't be all that
expensive.

Hello Sylvain,

For just 15 boards it can sometimes be less expensive to hire a temp from a local labor pool company. But it should be a technician who is experienced in fine pitch prototype build-up.

If you are still at Louvain University there may even be an institute that has technicians and could do it for a cross charge fee (or for the promise to throw a nice party...).

Well, you use your hands to lay the stencil on the board, and put the
assembly into the toaster oven... ;-)

Cheers!

You might consider Olimex http://www.olimex.com.

I've used these folks for PCB manufacture only, but their service was
excellent. Be sure to use courier shipping - my order stayed in the post a
lot longer than I would have liked!

Regards,
Alan

Could you tell me what "fiducials" are ? Google translate isn't of much
help ...

Target points.
Also known as "alignment points".
Also known as "register marks".
May have other aliases. ;-)

Sylvain,

Just add to what Rich said, a fiducial translates to "une mire" in french.

Not with a solder iron, of course. But we did quite a few in the lab.
Some technicians become very proficient with the heat gun or with ovens.

It's just that it will be tough to convince a regular fab to do a run
with a mere 15 units.

Not really. I've had a "regular fab" build as few as three stuffed
boards at a time. "Regular fabs" like money too. ;-) ...and it
really wasn't all *that* expensive, as far as prototypes go.
