Introduction of FR4 materials
FR in FR4 represents a flame retardant, and the number 4 distinguishes the material from other materials in this class.FR4 is a glass fiber reinforced epoxy laminate that looks like a thin woven cloth sheet. The term FR4 also represents the grade used to make these laminates. The fiberglass structure provides structural stability for the material. The glass fiber is covered with flame retardant epoxy. This gives the material durability and strong mechanical properties. All of these features make the FR4 printed circuit board very popular among electronic contract manufacturers.
