“370 hr” is a common PCB material type, which is a high-performance epoxy resin matrix commonly used to manufacture electronic equipment that requires high-temperature and high-frequency performance, such as high-speed communication equipment or aerospace equipment.
This material has good thermal stability and mechanical properties, making it suitable for complex circuit designs. It has an important impact on the performance and application of the board. In this article, we will introduce relevant information about 370 hr, including its definition, characteristics, application fields, advantages and disadvantages, etc.
370 hr is a high temperature and high performance fiberglass reinforced panel. It is composed of fiberglass and epoxy resin and has excellent electrical properties, mechanical strength and heat resistance.
The “370” in the name of 370 hr represents its glass transition temperature (Tg), which is 370°C. This means that under high temperature conditions, 370 hr can still maintain stable performance without softening or failure.
370 hr has the following features：
Good mechanical strength and high thermal performance: 370 hr plate has excellent high temperature performance, can maintain stable performance at higher temperatures, withstand large force and temperature changes, and is not easy to deform or crack. This makes it particularly suitable for electronic equipment in high-temperature environments, such as automotive electronics, aerospace equipment, etc.
Low mismatch: The material has a low coefficient of thermal expansion (CTE), which helps reduce PCB mismatch problems when temperature changes, improving the stability and reliability of the circuit board.
Excellent dielectric properties: 370 hr board has good dielectric properties, can provide good signal transmission and impedance control, and is suitable for high-speed digital and analog circuit design.
Mechanical strength: The material has good mechanical strength and impact resistance, and can resist vibration and physical damage, helping to extend the service life of electronic products.
Cost-Effectiveness: Although a high-performance material, 370 hr sheet is moderately cost-effective compared to other high-performance materials, providing an affordable option.
Excellent electrical insulation properties, can work in high voltage, high frequency and high current environments. Its insulation performance is stable and can effectively prevent electrical faults and fire accidents.
370 hr also has good chemical corrosion resistance and can be used for a long time in harsh environments such as acids, alkalis, and solvents.
Due to its many excellent properties, 370 hr has been widely used in many fields. First of all, 370 hr is widely used in electronic and electrical fields. It can be used as the base material of PCB (Printed Circuit Board) to manufacture high-performance electronic products, such as computers, mobile phones, communication equipment, etc.
Its excellent electrical properties and mechanical strength can ensure the stable operation and reliability of electronic products. Secondly, 370 hr can also be used to manufacture high-demand industrial products such as electrical equipment, power equipment, and aerospace equipment. Its heat resistance and chemical corrosion resistance can meet the requirements of various harsh working environments.
In addition, 370 hr can also be used in automobiles, ships, medical equipment and other fields to manufacture high-performance structural parts and components.
Although the 370 hr has many advantages, it also has some shortcomings. First of all, since 370 hr is a high-performance material, its cost is relatively high and processing is difficult. Secondly, the surface of the 370 hr is susceptible to scratches and wear and requires protective measures.
In addition, the color of 370 hr is relatively single, usually yellow or light green, which is not suitable for applications that require diverse appearances.
As a high-temperature and high-performance plate parameter, 370 hr has excellent electrical properties, mechanical strength and heat resistance. It has been widely used in electronic and electrical, industrial manufacturing, transportation and other fields.
However, its disadvantages such as higher cost and easy surface damage also need to be taken into consideration. With the continuous advancement of technology, I believe there will be more breakthroughs and developments in the performance and application fields of 370 hr.
