The full name of FR-4 epoxy board is FR-4 epoxy glass cloth laminate. According to different purposes, the industry is generally called: FR-4 Epoxy Glass Cloth, insulating board, epoxy board, brominated ring Oxygen resin board, FR-4, 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, 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 products, such as FPC reinforcement board, PCB drilling pad, glass Fiber meson, potentiometer carbon film printed glass fiber board, precision star gear (wafer grinding), precision test plate, electrical (electrical) equipment insulation support spacer, insulation backing plate, transformer insulation plate, motor insulation, grinding gear, Electronic switch insulation board, etc.
FR-4 is the code name of a kind of flame-resistant material grade. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade, so the current general circuit There are many types of FR-4 grade materials used in the board, but most of them are composite materials made of so-called Tera-Function epoxy resin, Filler and glass fiber.
