Fr4 insulation board is what material

FR-4 is a code for the grade of flame polyimide glass fiber, which means that the material of the resin material must be self-extinguishing. It is not a material name but a material grade. Therefore, the current general circuit There are a lot of FR-4 grades used in the boards, but most are composites made of so-called Tera-Function insulating resin and Filler and glass fiber. FR-4 Epoxy Glass Cloth, Insulation Board, Insulation Board, compressed laminated wood, Brominated Insulating Resin Board, FR-4, Glass Fiberboard, FR-4 Insulating Glass Cloth Laminate, FR-4 Epoxy Glass Cloth, FR-4 reinforced resin board, flame retardant insulation board, FR-4 laminated board, insulation board, FR-4 light board, FR-4 reinforced board, FPC reinforced board, flexible circuit board reinforcement board, FR- FR-4 glass plate, insulated glass cloth board, insulated glass cloth laminated board, circuit board drilling plate. Main technical characteristics and application: stable electrical insulation, smoothness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation requirements of products such as FPC reinforced board, PCB drilling pad, glass (Dielectric) equipment, electrical insulation (electrical equipment) insulation barrier strips, insulation pads, transformers insulation board, motor insulation, grinding gears, Electronic switch insulation board.
