IMOP, I don't believe there is any panacea called "Pwb Benchmark
Survey for Servic Bureaus". I can only relate what we have done over

I'd like to know if there is a minimum dielectric thickness between layers of 
a double/multilayer flexe similar to the requirement for rigid boards in 
IPC-D-275?  I've looked through some of the flex specs (IPC-D-249, 
IPC-FC-231, IPC-FC-250) and haven't found anything that specifies a minimum. 
 I would appretiate any help in locating this information, if there is any.

Thank you,
