We've had good results from Ascentec (http://www.ascenteceng.com/) for our 
flex circuit pallets and fixtures. 

Does the flex circuit have stiffeners?

Hi TechNet
We have been asked by a customer to build a flex assembly for them. It 
is not complex, and the smallest part on it is a SOT-23, so it should be 
pretty easy on the difficulty scale.  But we have not done full flex 
assemblies before, we have done rigid/flex assemblies but...

Obviously we will need carrying fixtures to transport the flex circuit 
through the SMT line, does anyone have any recommendations for vendors 
for this sort of thing?

And are there any serious gotchas I should consider?  Polyimide flex, so 
moisture/bakeout is obviously a consideration.
