What’s the Difference Between G10 and FR4

G10 and FR4 are important insulating materials for industrial electronic and electrical manufacturing, but some people may not be very familiar with these models and are easily confused. In addition, there are G11, 3240 and so on. So today we focus on the difference between G10 and FR4.

G10

The “G” in G10 represents glass fiber, and 10 represents 10% glass fiber. The G10 epoxy plate is made of glass fiber cloth and epoxy resin. It has a certain mechanical strength without deformation, and has good insulation strength, chemical resistance, radiation resistance and thermal shock resistance, good tensile strength, flexural strength and low temperature adaptability.

FR4 exactly should be FR-4 epoxy plate, the color is mainly yellow. Its raw material is imported electronic glass fiber cloth, and is a product suitable for high performance electronic insulation requirements. Excellent comprehensive performance and flame retardancy and halogen free are in line with EU standards. Therefore, this material is widely used and has excellent performance. It can be used as an insulating component in the reinforcement, motor and electrical equipment of various plates.
