Technet,
	A while back there was a potential material listed that could remove 
encapsulant.  The material is called URESOLVE PLUS from Dyanoloy.  Well, I 
called the company and got some more information.  Not fully understanding all 
the chemistry, they said it will work an epoxy with Anhydride based 
activation, but not on Amine based.
	So, my question to you all, what is the chemical basis of 
Photoresists, FR-4, GeTek(R), and Polyimide?  I'm not looking for trade 
secrets, just info that should be the MSDS sheets.

Thanks very much for your help.
