Electrical insulation green fiber glass fr4 epoxy sheet

FR4 is a common composite material and a widely used substrate material in the electrical and electronic industry.FR4 material is a thermosetting plastic composite material consisting of glass fibers and epoxy resin, which has excellent insulating, mechanical strength and heat resistance properties.

 Characteristics of FR4 material

FR4 material has the following characteristics:

1. Good insulating properties: FR4 materials have excellent electrical insulation properties and high reliability, and can be used to make high-voltage electrical appliances and electronic circuit boards.

2. High mechanical strength: FR4 material has high strength and stiffness, not easy to deform, can be used to make high requirements of mechanical equipment.

3. Good heat resistance: FR4 materials can withstand high temperatures, can be used to make high-temperature equipment and refractory materials.

4. Good chemical resistance: FR4 materials have good corrosion resistance, can be used in acid, alkali and other corrosive environments.

Application areas of FR4 material

FR4 material is a widely used substrate material in the electronic and electrical industry, mainly used in the production of printed circuit boards (PCB), insulating pads, insulating boards, transformers and other electronic components. Due to its excellent insulation, mechanical strength and heat resistance, it is widely used in high-speed circuit boards, RF circuit boards, high-frequency microwave equipment, aviation and spacecraft, automotive electronics, medical equipment and other fields.

Production process of FR4 materials

The production process of FR4 material includes fiber pretreatment, fiber preparation, mixture preparation, sheet production and so on. Specific processes are as follows:

1. Glass fiber pretreatment: the glass fiber is cleaned with deionized water and dried to the proper moisture content.

2. Glass fiber preparation: mix the pre-treated glass fiber with epoxy resin to prepare glass fiber composites.

3. Mixture preparation: Mix epoxy resin, hardener, filler, solvent and other materials according to a certain ratio.

4. Sheet production: the mixture is coated on the glass fiber composite material and cured by means of high temperature and pressure until FR4 material is formed.

Conclusion

As a common composite material with excellent insulation, mechanical strength and heat resistance, FR4 material is widely used in the electronic and electrical industries. Its production process is relatively simple, and at the same time, there are some limitations, such as its quality is easily affected by the fabrication process and production conditions. However, with the continuous progress of technology and the continuous expansion of the scope of application, FR4 materials have a very broad development prospect.
