FR4 is a common composite material that is widely used in the manufacture of electronic circuit boards. It consists of fiber glass cloth and imported epoxy resin, and has high mechanical properties, dielectric properties, electrical insulation properties. The insulation class is F, and the main colors are white (primary), light green, black and yellow.
FR4 has the following technical characteristics:
1.High mechanical properties: FR4 has high mechanical strength and can withstand large mechanical stress and are not easy to break or deformation, which makes them ideal for the manufacture of precision instruments and high-end equipment.
2.Excellent electrical performance: FR4 has stable electrical insulation performance, which can effectively prevent current leakage and short circuit and provide reliable guarantee for the safe operation of electrical equipment. Its high insulation resistance and low dielectric loss make it excellent in high-voltage electrical appliances, electronic circuits and other fields.
3.Good heat and moisture resistance: FR4 can maintain stable performance in high temperature and humid environments and it is not easy to deform or age, which makes it work normally under harsh environmental conditions.
4.Good flame retardant performance: FR4 has flame retardant performance, which can prevent the spread of fire to a certain extent and provide protection for the safe use of electronic products.
As a substrate material: FR4 is the core substrate material in PCB manufacturing. Its high dielectric strength, bending strength, impact strength and tensile strength make it able to meet a variety of complex circuit design needs. In PCB design, FR4 is used as the basic support structure of the circuit board to provide a stable installation platform for electronic components.
Improve the overall performance of the circuit board: Because FR4 has excellent electrical and mechanical properties, using it as a substrate material can significantly improve the overall performance of the circuit board. For example, it can provide better signal transmission quality, lower signal losses, and higher operating frequencies.
Enhance the reliability of the board: FR4’s flame retardant performance and good processing performance make it a key factor to improve the reliability of the board. It can maintain stable performance in harsh working environments. At the same time, it is easy to process into a variety of shapes and sizes to suit different electronic equipment needs.
Improve the safety of electronic products: The flame retardant performance of FR4 can effectively prevent the board from burning in a fire, thereby reducing the safety risk of electronic products.
Reduce production costs: FR4 is easy to process and manufacture, which can reduce the production cost of PCB and improve production efficiency.
Extend the service life of electronic products: FR4l has good durability and stability, which can extend the service life of electronic products and reduce the frequency of maintenance and replacement.
