Everyone can go through Google search to find out about this keyword. Almost every day people are searching. In our electrical industry, it is still quite popular. I think that my explanation of this may not be very good, so I refer to some of the information. Talk to everyone about this topic.
FR-4 Epoxy glass cloth laminates, depending on the use of different uses, the industry generally known as: FR-4 Epoxy Glass Cloth, insulation board, epoxy board, brominated epoxy board, FR-4, fiberglass board ,Glass Fiber Board,FR-4 Reinforcement Board,FPC Reinforcement Board,Flexible Circuit Board Reinforcement Board,FR-4 Epoxy Resin Board,Flame Retardant Insulation Board,FR-4 Laminate Board,FR- 4 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate board, circuit board drilling pad. The main technical features and applications: stable electrical insulation, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation products. FR-4 uses FR-4 epoxy glass fiber board (epoxy board), the main material is imported prepreg, the color is white, yellow, green, still high mechanical strength at room temperature 150 °C, dry, wet electrical Good performance, flame-retardant, used in electrical and electronic industries and other insulation structure parts, using imported raw materials, domestic presses and standard processes carefully manufactured; The main specifications are 1000*2000mm1020mm*1220mm.
Insulation Board Standard In China:
Power distribution room voltage 10KV selected 8mm thick industrial frequency withstand voltage test 10000V 1 minute without breakdown, in the frequency withstand test 18000V, 20 seconds breakdown. Distribution room voltage 35KV 10-12mm thick frequency withstand voltage test 15000V 1 minute No breakdown, in the frequency withstand voltage test 26000V, 20 seconds breakdown. Distribution room low voltage selection 5mm thickness 500V below the frequency frequency withstand voltage test 3500V 1 minute does not breakdown, in the industrial frequency withstand voltage test 10000V, 20 seconds do not hit wear!
