Features
Flame retardancy
Electrical insulation performance
Processability
Humidity and chemical resistance
FR4 meets the UL 94V-0 flame retardant standard, which means that it will not support combustion in the event of a fire and can extinguish itself. This feature is particularly important for all electronic products that need to meet strict safety regulations.
FR4 is an excellent electrical insulation material with high resistance and low dielectric constant. This allows FR4 sheets to effectively prevent current leakage and short circuits, ensuring the safe operation of electronic equipment.
6mil (0.15mmFR4 sheets are easy to cut, drill, and mill, and can be precisely processed into various sizes and shapes to meet specific design requirements. This processing flexibility is why FR4 is widely used in various complex circuit board designs.
FR4 has good resistance to humidity and various chemicals, and can prevent damage caused by moisture and chemical corrosion. This feature ensures reliability and long-term stability under various environmental conditions.
