FR4 Copper clad laminate/CCL Sheet made by glassfabric, epoxy resin and copper foil with clad electrolytic lamination technique. It has excellent electrical conductivity, It has excellent electrical conductivity, mechanical and flamer retardant properties.
"FR" stands for flame retardant, and denotes that safety of flammability of FR4 is in compliance with the standard UL94V-0. FR-4 is created from the constituent materials (epoxy resin, woven glass fabric reinforcement, brominated flame retardant, etc.) by NEMA in 1968.
FR-4 Epoxy Fiberglass Sheet is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its
