FR4 Epoxy Fiberglass Sheet,FR-4 refers to a designation for a flame-retardant material grade, indicating that the resin material must be able to self-extinguish when in a burning state. It is not a specific material name but rather a material grade. Therefore, there are many types of FR-4 grade materials commonly used in circuit boards. Most of them are composite materials made of so-called Tera-Function epoxy resin, fillers, and glass fiber.
FR4 Epoxy Glass Cloth Laminated Sheet, depending on its application, is commonly referred to as FR-4 Epoxy Glass Cloth, Insulation Board, Epoxy Board, Epoxy Resin Board, Brominated Epoxy Resin Board, FR-4, Glass Fiber Board, Fiberglass Board, FR-4 Reinforcement Board, FPC Reinforcement Board, Flexible Circuit Board Reinforcement Board, FR-4 Epoxy Resin Board, Flame Retardant Insulation Board, FR-4 Laminated Board, Epoxy Board, FR-4 Optical Board, FR-4 Fiberglass Board, Epoxy Fiberglass Cloth Board, Epoxy Glass Cloth Laminate, and PCB Drilling Pad. Its main technical features and applications include stable electrical insulation properties, good flatness, smooth surface, no pits, standard thickness tolerance, and suitability for products with high-performance electronic insulation requirements such as FPC reinforcement boards, PCB drilling pads, fiberglass substrates, carbon film printed glass fiber boards for potentiometers, precision star gears (wafer grinding), precision test materials, electrical equipment insulation support sheets, insulation pads, transformer insulation boards, motor insulation components, grinding gears, and electronic switch insulation boards, etc.
