    FR4 Epoxy Glass Sheet: A Comprehensive Analysis of the Versatile Substrate

    FR4 Epoxy Glass Sheet is a glass fiber reinforced epoxy laminate widely used in electronics and industrial insulation. It offers excellent mechanical strength, stable electrical insulation, UL94 V-0 flame resistance, and good machinability, making it ideal for PCBs and industrial control systems. While it performs reliably in most standard applications, it has limitations in high-frequency signal transmission, thermal conductivity, and long-term UV exposure. Overall, FR4 remains a highly cost-effective and versatile engineering material for general electronic and industrial use.
