Fiberglass board FR-4 is a code name for the grade of fire resistant epoxy board. It means a material specification that the resin material must be self-extinguishing after being burned. It is not a material name but a material grade, Therefore, there are many types of FR-4 grade materials used in general circuit boards, However, most of them are composite materials made of so-called four-function (Tera-Function) epoxy resin plus filler (Filler) and glass fiber.
FR-4 Epoxy Glass Cloth Laminate, according to the use of the industry, the industry is generally called:
FR-4 Epoxy Glass Cloth, Insulation Board, Epoxy Board, Epoxy Resin Board, Brominated Epoxy Board, FR-4, Fiberglass Board, FR-4 Reinforced Sheet, FPC Reinforced Sheet, Flexible Circuit board reinforcement board, FR-4 epoxy resin board, flame retardant insulation board, FR-4 laminated board, FR-4 light board, FR-4 glass fiber board, epoxy glass cloth board, epoxy Glass cloth laminate, circuit board drilling pad.
Main technical features and applications:
Stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high performance electronic insulation requirements, Such as FPC reinforcing plate, PCB drilling pad, glass fiber meson, potentiometer carbon film printing fiberglass board, precision star gear (wafer grinding), precision test board, electrical equipment insulation struts, insulation mat Board, transformer insulation board, motor insulation parts, grinding gears, electronic switch insulation boards, etc.
