Youwei Poly (Shanghai) New Materials Technology Co., Ltd. is a high-tech materials R&D and production enterprise that uses advanced foreign manufacturing equipment and cooperates with the raw material formula technology developed by the team to specialize in the R&D, production and sales of new materials for 5G communications. Products include liquid crystal polymer materials for flexible substrates, advanced ceramic materials, functional sensing materials, high-performance alloy slurries, etc. Committed to becoming an advanced material solutions provider in the 5G communications industry.

At present, my country's flexible copper-clad laminate (FCCL) industry has strong demand. In the future, with the development trends of commercial 5G, millimeter wave, aerospace and military industry, and future ICT technology, the demand for high-frequency and high-speed copper clad laminate will show exponential growth. Emerging demands such as 5G, automotive electronics, and IOT will bring good development opportunities to the flexible copper clad laminate industry.

In 2021, my country's flexible copper-clad laminate sales will be 64.2 million square meters. In 2021, affected by favorable factors such as the rapid recovery of the national economy after the epidemic, my country's flexible copper-clad laminate industry sales revenue reached 3.92 billion yuan. The scale of industry sales revenue has increased significantly compared with the 2020 epidemic period.

Industry issues:

Product Features:

What is LCP film?

LCP film is aromatic thermoplastic polyester, a new type of special engineering plastic. It has the characteristics of low moisture absorption, high chemical resistance, and high gas barrier properties. It is a dielectric material with low dielectric constant and low dielectric loss factor, making 5G technology higher frequency and higher speed.

What is the application industry chain for such products?

The application of LCP from resin material to mobile phone antenna module requires the following steps: LCP resin-film-flexible copper-clad laminate FCCL-flexible circuit board FPC-antenna module. LCP resin is processed to obtain LCP film. The LCP film is copper-coated by FCCL manufacturers to obtain FCCL. FPC companies then process FCCL into FPC, which is then integrated through module companies and sold to terminal mobile phone manufacturers.

What are the advantages of LCP film?

The material properties are uniform, the electrical properties are stable, the fluctuation is small, and the welding heat resistance is high; compared with the PI film, it has a lower dielectric constant and dielectric loss factor, and compared with the PI film, it has lower water absorption and water Vapor transmittance. It has stable electrical properties and good dimensional stability in high-humidity environments. It can be directly hot-pressed and laminated with copper foil and other materials. It is easy to drill, resistant to bending, and has good processing and formability.

What is the product supply capability of Youwei Polymer?

LCP film, 3~4μm ultra-thin LCP film annual output can reach more than 500,000 m2, other specifications can produce 200,000 m2 annually, LCP-FCCL: 15,000~20,000 m2/month.
