F881, equivalent to NEMA FR4 and IEC EPGC202, offers high mechanical strength at room temperatures, good electrical performance under both dry and wet conditions, UL94V-0. F881A is designed for mechanical, electrical and electronic applications.
The mechanical properties, dimensional stability, impact resistance and moisture resistance of F881 are higher than those of paper substrate. Its electrical performance is excellent, the operating temperature is high, and its own performance is little affected by the environment.
