Hopefully my lil nugget of info will help.....
FR-1-A low-grade version of FR-2.
FR-2-A NEMA grade of Flame-Retardant industrial laminate having a substrate
of paper and a resin binder of phenolic. It is suitable for printed circuit
board laminate and cheaper than the woven glass fabrics such as FR-4.
FR-4-A NEMA grade of Flame-Retardant industrial laminate having a substrate
of woven-glass fabric and resin binder of epoxy. FR-4is the most common
dielectric material used in the construction of PCBs.
FR-6- Fire-Retardant glass-and-polyester substrate material for electronic
circuits. Inexpensive; popular for automobile electronics.
Those wanting to be really "Geeked" up...Hopefully this will give a little
more insight: http://www.ilnorplex.com/quickref.htm
