What is FR4 PCB – A Complete Guide to FR4 Material and Its Applications

FR4 PCB (Epoxy Glass Fiber Copper Clad Laminate) is the core substrate of the modern electronics industry. With its UL94-V0 flame retardant certification, excellent electrical insulation and mechanical strength, it has become the first choice in consumer electronics, automotive systems, medical equipment and other fields. It is made of fiber cloth and epoxy resin, and has thermal stability (tolerance to high temperature environment), moisture resistance and corrosion resistance, and can adapt to high-frequency/high-power scenarios by adjusting the material ratio.
