What is FR-4

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. The substrate is a composite material in nature, achieved by combining fiberglass and epoxy resin.
