FR4 is a class of printed circuit board base material made from a flame-retardant epoxy resin and glass fabric composite. FR stands for flame retardant and meets the requirements of UL94V-0. FR4 has good adhesion to copper foil and has minimal water absorption, making it very suitable for standard applications. FR4 is either used as a copper-coated material for 1 and 2-layer PCBs or is used for multilayer PCBs as a Prepreg and core.
FR stands for flame retardant, and the number ‘4′ indicates woven glass-reinforced epoxy resin. The characteristics of FR4 vary significantly depending on the manufacturer, although it is commonly known for its mechanical strength and water resistance. This material performs as an insulator in PCBs by isolating adjacent copper planes while also providing overall mechanical strength.
FR4 is the most commonly used material in PCB manufacturing. These boards are durable, water-resistant, and provide excellent insulation between copper layers, reducing interference and ensuring signal integrity. However, FR4 is not the greatest material to utilize in the boards operating at high frequencies or in harsh situations.
