It stands for "Fire Resistant grade 4", or something like that and it is the common name for the fibreglass board in high- quality copper-clad printed circuit board. It's the green (usually) stuff that is very strong but tough to cut, blunts HSSteel drills quickly and makes nasty dust. I guess that's probably all you need to know, but if you want technical detail you now have enough info to Google it. Regards, LenW

It stands for "Fire Resistant grade 4", or something like that
and it is the common name for the fibreglass board in high-
quality copper-clad printed circuit board.
It's the green (usually) stuff that is very strong but tough to
cut, blunts HSSteel drills quickly and makes nasty dust.
I guess that's probably all you need to know, but if you want
technical detail you now have enough info to Google it.

IF I recall correctly, at one time this material was called "G-10 Epoxy". Roland F. Harriston ******************* Len Warner wrote:
