For FR4 materials, friends who are concerned about Weibang composite materials should know it. It is the FR4 sheet we often say. We also said that our FR4 insulation sheet is a very good quality sheet with good flame retardancy. FR4 It is our name for the flame resistance grade of the board. Because of the different materials in the production of FR4 boards, the colors and properties of it are also different. Weibang Composites will take you to know what FR4 boards are What materials are made, and what are the advantages.

Interpretation of fr4 copper clad laminate

The technical term is also called glass fiber epoxy copper clad laminate, which is mainly used for circuit boards. This FR4 copper clad laminate was used on many previous motherboards, such as the green board in small game consoles.

FR4FR5 epoxy board is a laminate product made of special electronic cloth impregnated with epoxy phenolic resin and hot pressed at high temperature and high pressure. It has high mechanical properties and dielectric properties, good insulation properties, heat resistance and moisture resistance, and good machinability. Application: Used as insulating structural parts in motors and electrical equipment, and also widely used For PCB testing; and can be used in humid environment conditions and transformer oil.

Interpretation of fr4 features

The main technical characteristics and application of fr4 sheet: electrical insulation, stability, 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.

FR-4 mentioned earlier that it is a designation for the grade of flame-resistant materials. The main test is 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 there are many types of FR-4 grade materials used in general circuit boards, but most of them are made of so-called tera-function epoxy resin plus filler (Filler) and glass fiber. Made of composite materials. FR-4 epoxy glass cloth laminate, according to different uses, the industry 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.
