Hi Scott, sorry I just saw this now.

 

If you can't use FR-4 then just use extra Kapton (Polyimide) in the
appropriate thickness.  I can take a look at the design if you like.

Subject: [DC] Stiffener material for medical application

 

I'm working on a flex circuit design that will be using a stiffener
placed

below two SMT components. I'm not exactly sure where the part will be
used,

but it is a medical application and the customer has informed me that it

must be FDA approved for medical use and that  good old FR4 is not

acceptable. I need something as thin as possible, but it still must be
rigid

and hold up to the heat required to assemble the components to the flex.

Oh, it's got to be fairly cheap and readily available as well. 

 

Any suggestions or a point in the right direction is appreciated.
