These are remnants from MIL-S-13949. GF is equivalent to good old FR4. I'd
forgotten what the difference between N and Y was. Thanks, Charlie. As for
references, page 19 of IPC 4101 has a list of the current designation as
well as old NEMA and Military designations, including GF.
Arlon has a little downloadable Windows help file for the IPC 4101
designations that I first learned about on Technet a few months ago. I've
found it to be really helpful also.
