FR4 is a code name for the grade of flame-retardant materials. 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. Therefore, the general circuit board there are many types of FR-4 grade materials used, but most of them are composite materials made of so-called Tera-Function epoxy resin, Filler and glass fiber. FR-4 epoxy glass cloth laminate, according to different uses, is generally called FR-4 Epoxy Glass Cloth, insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4 , Fiberglass 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 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad.
FR4 main technical features and applications: electrical insulation - stable, good flatness, smooth surface, no pits, thickness tolerance standard, suitable for high-performance electronic insulation products, such as FPC reinforcement board, PCB drilling Backing plate, glass fiber meson, potentiometer carbon film printed glass fiber board, precision star gear(wafer grinding), precision test plate, electrical(electrical) equipment insulation strut partition, insulation backing plate, transformer insulation plate, motor insulation parts , Grinding gears, electronic switch insulation boards, etc. FR4 is very common used for the Printed Circuits Boards manufacturing, that's why we call it Conventional FR4 PCB.
There are a lot of key parameters of FR4 PCB material, like Tg, Td, CTE (Z-axis), Thermal Stress, Volume Resistivity, Surface Resistivity, Dielecric Breakdown, Dissipation Constant (Dk), Dissipation Factor (Df), Peel Strength, Water Absorption and CTI, Flammability etc. While one of the most important parameter is the Tg value, generally there are Tg130℃, Tg140℃, middle Tg150℃, high Tg170℃, high Tg180℃, high Tg250℃ FR4 PCB, you can chose the right Tg for your specific product. In Union, we have various kinds of PCBs material from different material vendors in stock to meet our all customer needs, like ShengYi, Kingboard, Goworld, ITEQ, Isola etc.
