GFN comes from Mil-S-13949
I don't have a copy but I think G=glass fibre. F=flame retardant epoxy.
N=natural colour

Geoff

Subject: [TN] "N" designator
Hello Tech Netters
We have a customer spec for a board that says: GFN0620
I know it's FR4 (GF=Glass Fiber) and the thickness is .062 (0620)
But, what does the "N" designate?
As a side note, what IPC Spec covers these definitions? (not in 600 or
6012)
Thanks
Tom
