FR4 properties and materials
FR4 is a standard defined by the NEMA (National Electrical Manufacturers Association) for a glass-reinforced epoxy resin laminate.
FR stands for “flame retardant” and indicates that the material is compliant with the UL94V-0 standard on plastic material inflammability. The 94V-0 code can be found on all FR-4 PCBs. It guarantees the non-propagation of fire and its rapid extinguishing when the material burns.
Its glass transition (TG) is of the order of 115°C to 200°C for the High TGs or HiTGs depending on the manufacturing methods and the resins used. A standard FR-4 PCB will have a layer of FR-4 sandwiched between two thin layers of laminated copper.
FR-4 uses bromine, a so-called halogen chemical element that is fire resistant. It replaced G-10, another composite that was less resistant, in most of its applications.
FR4 has the advantage of having a good resistance-weight ratio. It does not absorb water, keeps high mechanical strength and has a good insulating capacity in dry or humid environments.
