What is FR4 flame retardant epoxy resin fiberglass laminate sheet material?

According to different uses, the industries of FR4 flame retardant epoxy resin fiberglass laminate sheet are generally called: FR4 epoxy glass cloth, insulation board, epoxy board, epoxy resin board, brominated epoxy resin board, FR4, glass fiber, glass fiber board, FR4 reinforcement plate, FPC reinforcement plate, flexible circuit board reinforcement plate, FR4 flame retardant epoxy resin board, laminated board, FR4 epoxy plate, epoxy glass cloth board, epoxy glass cloth laminated sheet and PCB drilling pad.

Main technical features and application of FR4 sheet: electrical insulation, good stability and flatness, smooth surface, no pits, thickness tolerance standard, suitable for application in high performance electronic insulation requirements of products, such as FPC reinforcement plate, PCB drilling pad, fiberglass meson, potentiometer carbon film printing glass fiber board, precision tour stars gear grinding (chip), precision test plate, electrical equipment insulation stay clapboard, insulating plate, transformer insulation board, motor insulation parts, grinding gear and electronic switch insulation board, etc.

Firstly, FR-4 flame retardant epoxy resin fiberglass laminate sheet material is a kind of code of fire resistant material grade, represented by the resin material must be able to put out after combustion state. It is not a material name, but a level of material. So the general FR4 materials used in the circuit board has a lot of kinds, but most are based on the so-called four functions (Tera - Function) of epoxy resin, filler and glass fiber made of composite materials.
