We've recently started the NPI process for a new assembly using FR-5 laminate.  A week ago I'd never heard of FR-5 and don't know much about it.  
	Does anyone have experience with FR-5?  
	Sources of laminate?  
	Key differences from FR-4?  
Then for my information, what would be the driver to specify this material?  

Any input on sources should be offline.  Thanks in advance.
