4 layer prototypes?
« on: June 11, 2011, 03:07:24 am »
I need to make my design smaller, and the only way to do that is with a 4 layer pcb. I've seen the threads about where to get pcb prototypes made cheaply, but cheap appears to only apply to 2 layer boards. Everywhere I've looked it's at least $200 for a small 4 layer prototype. Where do you guys get your 4 layer prototypes made and what do they cost if you don't mind me asking?

You will want to jump on the DorkbotPDX order.  http://dorkbotpdx.org/wiki/pcb_order

Next 4 layer board order goes in on June 20th.  $10 per sq/inch for 3 boards.  Any color as long as you like purple.  :)   I haven't received my 2 layer boards from the order yet, but everyone seems to love the quality of the boards.  They are pretty high spec.

This doesn't make sense for large boards, but is a great service for getting small boards prototyped.

You didn't say what the total area of your board is and what qty
you want. 

In my experience, no one PCB maker has the best prices -- it really
depends on a lot of factors.

What are your trace/space requirements?

Definitely will be smaller than 6 square inches, hopefully I can get it smaller than that. First run will be a prototype so quantity can be as small as 1, but basically whatever is cheapest.

I've generally been designing for maximum compatibility with manufacturers so I haven't needed minimums. I suppose if I really get cramped for space I should look at 6/6.

I don't recall ever seeing a 4 layer service with rules bigger than 6/6

www.batchpcb.com

sparkfun set this up iirc. its $8 sq/in. I used them alot and a 4 layer job some time ago and they were good.Only issue can be that the 4 layer panel doesnt fill up fast so you may have to wait. Otherwise panelize a job yourself and send it directly into goldphoenix.biz (this is who batch use iirc) and I suspect you may come out with the entire panel for about 200 but it will depend on screens colors and tolerances.

When you get up to qty 10, you can get boards for $23.70
each from pcbex.com.  6 mil trace/space 10 day turn.

I've ordered two layer boards from them, but not four layer.
They have a US office and the boards and made and shippped
to you from China.
