Fr4 glass transition temperature
WebMataas na TG PCB. High TG PCBs are designed to operate in high-temperature environments, and they have a glass transition temperature that is greater than 170℃. These PCBs are engineered with features such as high-temperature durability, strong mechanical strength, high power density, and exceptional reliability. FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material. FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a …
