FR4 is the most common material grade that comprises fabricated circuit boards. ‘FR’ indicates the material is flame retardant and the ‘4’ indicates woven glass reinforced epoxy resin. Single or double-sided PCB structures consist of an FR4 core and top and bottom copper layers. Multilayer boards have additional prepreg layers between the center core and top and bottom copper layers. Now, the core consists of a substrate with copper covering, also referred to as a copper clad laminate. The core, laminate, and prepreg may all be FR4 with the copper sheets between the signal and ground layers.
The properties of FR4 may vary slightly depending on the manufacturer; however, it generally has favorable strength and water resistance attributes that support its widespread usage as an insulator for many electrical applications. It serves the same purpose in PCBs, namely to isolate adjacent copper planes and provide overall bending and flexural strength for the structure. FR4 is a good general purpose material for PCB fabrication.

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.
