Processing fr4 epoxy glass sheet

Epoxy Fiberglass Sheet, 3240 Epoxy Glass Sheet, Fr4 Sheet, Insulation Sheet. G10/Fr4 plastic machining  is a thermosetting industrial laminate consisting for a continueous filament glass cloth material with an epoxy resin binder. This product first introducted in the 1950's,has characteristics of high strength, excellent electrical properties and chemical resistance. These properties are maintained not only at room temperature but also understand humid or moist conditions. Fr4 Sheet Key Features : • Flame resistance • High dielectric strength • Moisture resistance • Heat resistant • Temperature resistance: 180-200℃ • Under the normal temperature 150 ℃, it still has high mechanical strength. FR4 is not a material`s name, but a kind of grade of fire-resistant, which represents resin materials can self-extinguish when firing. Now there are all kinds of FR4 materials using as PCB,…
