If you're in the states I'd look at MFLEX in Anaheim.

They've actually increased net sales in the first quarter 2009.

I've used them in the past and they're pretty good.

Subject: [TN] High Quality Flex Vendor Request

Dear Colleagues:

I am involved in the design of a critical medical product which 
requires the use of a multi-layer rigid flex board.  This board 
(flex) has a 2 layer section, and a 4 layer section.  The thickness 
tolerance is ultra critical, and the 2 layer section cannot exceed
0.004" max.

I am looking for a high quality vendor that can reliably produce / 
reproduce a product with a 4 mil max thickness on a double sided flex.

Thanks in advance for your recommendations.

Dave.
