21 Οκτ 2024 · FR4 PCBs have emerged as the industry standard of the modern electronics industry. FR4 provides outstanding mechanical strength and insulating properties from a woven fiberglass cloth with an epoxy resin binder. The "FR" designation indicates that the material is flame retardant, so it is appropriate for many different demanding uses.
23 Αυγ 2022 · The FR-4 is the most common dielectric material used in Printed Circuit Boards. This base material separates copper layers in the PCBs and provides mechanical support to the PCBs. It is a National Electrical Manufacturers Association (NEMA) standard for glass-reinforced epoxy laminate material.
