Specify What Industries FR4 Is Used In?

Hits : 4

FR4, also known as fiberglass sheet, is a glass fiber reinforced material with excellent insulating, physical, thermal and chemical stability. It is commonly used to make high-performance electronic products, such as circuit boards and other conductive components, and has become one of the standard materials in the electronics industry. Specifically, FR4 sheet has a wide range of applications in the following industries:

Electronics Manufacturing:  

FR4 sheet is often used as a substrate material for circuit boards, which not only ensures the stability and reliability of circuit boards, but also makes FR4 the most commonly used substrate material for printed circuit boards (PCBs).FR4 copper-clad laminates also play a key role in this field, and different grades of FR-4 copper-clad laminates, such as FR-4 Grade A1, FR-4 Grade A2, FR-4 Grade A3 and FR-4 A4 grade, respectively, are suitable for different fields such as military, communications, computers, digital circuits, industrial instrumentation, automotive circuits, advanced home appliances and general electronic products.

Electricity and Communication:  

FR4 sheet can be used as partition and isolation material in the electric power system to ensure the electrical safety of the equipment and avoid accidents caused by electrical failure. Meanwhile, FR4 copper clad laminates are also widely used in the field of communication, such as 5G, Internet of Things and other emerging industries, all of which have greatly contributed to the growth of market demand for FR-4 copper clad laminates.


FR4 sheets are also used in aerospace due to its excellent physical and thermal properties.

Mechanical & Automotive:  

FR4 sheet is also used as a material for mechanical parts, such as machine tool partitions and automobile engine covers, thanks to its excellent mechanical properties and chemical stability. In the automotive industry, FR4 copper-clad laminates are also used in the manufacture of automotive circuits and other components.


Medical Devices and Biotechnology:  

In the medical devices and biotechnology fields, FR4 sheet's insulating properties and chemical stability make it an ideal material for making medical devices. For example, it can be used to make circuit boards in medical instruments to ensure the stability and accuracy of the equipment.
