circuit board production

Started by Unknown April 12, 2007
Some of you may remember me from the thread I started a month or so ago 
about building my own keyboard.  Well, now I'm up to my eyeballs in the 
USB and HID specs and AVR datasheets.  I've actually got something 
working using Atmel's AT90USBKey demo board.

Now that I'm getting close to knowing what I want to build 
hardware-wise, how do I go about getting it produced?  The AVR 
microcontroller I'm using (AT90USB1287) is way too small for me to 
manually build a board.  Are there places that will build a board to my 
specs in low volumes and affordable prices?  Or am I going to be 
limited in my choices to ICs with old-school packaging?

Any suggestions would be a great help, as this is yet another area I'm 
entering that I have no experience in.

Thanks

Yes, that's what we do. We design boards to customer's spec.

Actually, we prefer QFN over TQFP. Smaller chip will have lower product cost. They are tough to prototype, but assembly houses don't care. Just treat the QFN as ball-less BGA with outer rows only. Unlike BGA, QFN can be inspected and reworked manually as well.

We have prototype board for the AT90USB1287, contact us if interested. me at linnix dot com

Thanks for the reply. I tried to email you at 'me at linnix dot com', but it bounced. I tried 'linnix at linnix dot com' as well, but have received no reply. Is there a better address?

Here is a picture of the prototype board using MLF64 or QFP64. There is also a contact us form at the bottom. http://linnix.com/proto

You may give these guys a try: http://www.custompcb.com/index.html I've had good results from them so far and they are especially cheap for me since I'm in Kuala Lumpur and can simply pick up my PCB by driving to their office ;-) You'll have to factor in shipping cost. These guys specialise in prototyping to the extent that they max out their production capacity at 500 pieces (1000 if single sided). Minimum quantity is 2.
