Re: gEDA-user: Anybody ever had a board assembled (pick and place)?

I sometimes get boards done at 4pcb, I didn't know they do assembly.
How much to they charge? And how big of a reel do you have to send
them? And you just cut tape the amount of parts you need to assemble
the amount of boards you want to manufacture?
A length of tape with no reel can be put onto a spare reel quite
easily, there's usually no charge.  The tape does need a leader of
around 300mm (varies) that has no components.  If your tape has no
leader then one option is to junk the components on the leader length
- not very expensive if you're talking about 60 millicent resistors
but a problem for expensive components.
One house I've worked with is Advanced Assembly, which is just down the street from Advanced Circuits. (They'll pick your boards up from 4PCB's will-call.) IIRC, it was ~$100 for the first moderate board (150 or so SMT components), add ~$30 if you do SMT on both sides, and $0.50 per thru-hole device. Additional boards run cheaper, as usual, and they will do a quick-turn on the first two or three boards and send them to you to verify before populating the rest of the order. The quick-turn boards are billed at the same rate as the rest of the order, so you don't pay a premium on them.

A Assembly will purchase components on your behalf, but of course you pay a bit extra for that. If you 'kit' the components yourself, you can send them your BOM and they will send back kitting labels similar to what you get on Digikey parts (mfg, mfg PN, refdes, description, internal bar-code, etc.) that you stick onto your components, either reel or cut-tape. They can do 0603s reliably, 0402s have a significant mortality rate.
