5G commercial is about to sprint, these PCB and FPC materials are more popular

2019-09-26 10:14:43
5G communication is a communication technology that relies on semiconductor materials and devices to realize long-distance transmission, transmission and reception and processing of wireless electromagnetic waves.

Compared with traditional 4G and other communication technologies, 5G needs to meet the three basic performance requirements of full spectrum access, high frequency band and even millimeter wave transmission, and high spectral efficiency. Therefore, higher performance and upgrade requirements are also required for device raw materials, such as large-scale. Integration, materials with high dielectric constant and low dielectric loss, and materials with high electron mobility.Multilayer pcb manufacturer china.

According to IHS research institutes, by 2035, the 5G industry chain alone will reach 3.5 trillion US dollars of economic output, and will create 22 million jobs.

What is more noteworthy is that 5G will create a value of US$12.3 trillion for sales activities in multiple industries around the world, which will account for 4% of the total global sales activity!China Rigid-flexible pcb on sale.

Which polymer materials are more popular in the 5G era?

The thermoplastic material polytetrafluoroethylene (PTFE) is resistant to high temperatures and operates at temperatures up to 250 °C. It has low dielectric constant and dielectric loss over a wide frequency range, and high breakdown voltage, volume resistivity and arc resistance, making it an ideal PCB material.

With the advent of 5G technology, LCP (industrial liquid crystal polymer) has become an ideal antenna material. It is a new type of high-performance special engineering plastic developed in the early 1980s, which generally exhibits liquid crystallinity in the molten state.Remote Control PCB solution.

As a non-crystalline material, MPI has a wide operating temperature and is easy to handle under low-temperature pressed copper foil. The surface can be easily connected to copper. Therefore, MPI materials may become a popular material for 5G equipment in the future.

The radome should have good electromagnetic wave penetration characteristics and be mechanically resistant to external harsh environments such as storms, ice, snow, and solar radiation.

The most popular PC/PMMA composite sheet is made by co-extruding (non-alloy material) of PMMA and PC, including PMMA layer and PC layer. After the PMMA layer is hardened, it can reach a pencil hardness of 4H or more, which ensures the scratch resistance of the product, and the PC layer can ensure sufficient toughness and ensure the overall impact strength.
