From the old MIL-S-13949 Reinforcement Material, G = E-Glass, woven Resin System, F = Epoxy, flame resistant Special Consideration, N = Natural color for resin system John Parsons -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Chris Ball Sent: Tuesday, March 14, 2006 8:11 AM To: [log in to unmask] Subject: [TN] TYPE GFN Laminate Hello Oracles, etc... Within our standard note for specifying bareboard material is a reference to "TYPE GFN". Anyone out there know what that means? I sure don't... A quick googling finds other folks out there referencing it (along with definitions like 'Good For Nothing' and "Gone For Now'), but I couldn't locate an explanation of it's meaning related to FR4... Thanks and Happy Tuesday, -Chris "This e-mail message is intended only for the use of the intended recipient(s).
