Brief introduction of FR4 PCB
May 18, 2017

FR-4 is a fuel-resistant material grade code, which means that the resin material must be able to extinguish the combustion state of a material specification, it is not a material name, but a material grade, so the current General circuit board used FR-4 grade material has a very many kinds, but most are with the so-called four function (Tera-Function) epoxy resin plus filler (Filler) and fiberglass made of composites.

FR-4 Epoxy Glass cloth laminates, according to the use of different industries, commonly known as: FR-4 Epoxy Glass Cloth, insulation board, epoxy plate, epoxy resin plate, brominated epoxy resin plate, FR-4, glass fibreboard, fiberglass board, FR-4 reinforcing plate, FPC reinforcing plate, flexible PCB reinforcement plate, FR-4 epoxy plate, flame-retardant insulation board, FR-4 layer plate, epoxy plate, FR-4 plate, FR-4 fiberglass board, epoxy glass cloth plate, Epoxy glass cloth laminate, PCB drilling pad. Main technical features and applications: Electrical insulation [1] can stabilize, smoothness, smooth surface, no pits, thickness tolerance standard, suitable for high-performance electronic insulation requirements of products, such as FPC Reinforcement Board, PCB drilling pad, fiberglass meson, potentiometer carbon film printing glass fibreboard, Precision star gear (wafer grinding), precision testing plates, electrical (electrical appliances) equipment Insulation-strut clapboard, insulating pad, transformer insulation board, electrical insulation parts, grinding gears, electronic switch insulation boards.
