Basic introduction of FR4 epoxy glass fiber board

FR4 epoxy glass fiber board alias: glass fiber insulation board, glass fiber board (FR-4), glass fiber composite board, etc., composed of glass fiber materials and high heat-resistant composite materials, and does not contain asbestos harmful to the human body. . It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good processability.

FR4 epoxy glass fiber board can give full play to its mechanical properties under medium temperature; under high temperature environment, it can give full play to its electrical properties. Therefore, due to these characteristics, epoxy board is very suitable for high-insulation structural parts in the electrical and electronic fields. It has higher mechanical strength and resistance to voltage breakdown than the national standard 3240 board.
