LCP film offers advantages such as low coefficient of thermal expansion, low moisture absorption, good dimensional stability, and low dielectric constant, and is expected to find widespread application in the FCCL manufacturing process in the future.

LCP-FCCL, full name Liquid Crystal Polymer Film Flexible Copper Clad Laminate, abbreviated as LCP film-type FCCL, is a copper clad laminate made with LCP film as the base material. LCP-FCCL features low moisture absorption, good dielectric properties, and high-temperature resistance, holding potential application value in communication systems, automotive electronics, and consumer electronics.

In recent years, with the continuous efforts of domestic enterprises and related research institutions, the number of LCP-FCCL-related patents in China has been increasing, including titles such as , , and . With further research and technological advancements, the development pace of China's LCP-FCCL industry is expected to accelerate.

Traditional FCCL is primarily made from raw materials such as polyimide film (PI), polyethylene naphthalate film (PEN), and polyester film (PET). PI film has defects such as high moisture absorption and susceptibility to curling, making it unable to meet the preparation requirements for high-performance FCCL. LCP film offers advantages such as low coefficient of thermal expansion, low moisture absorption, good dimensional stability, and low dielectric constant, and is expected to find widespread application in the FCCL manufacturing process in the future. In the early stages of industry development, the core preparation technology for LCP film was dominated by countries such as Europe, the United States, and Japan. In recent years, with improved technological maturity, the localization process of China's LCP film market has accelerated, providing favorable conditions for the development of the LCP-FCCL industry.

According to the <2026 Global and China LCP-FCCL (Liquid Crystal Polymer Film Flexible Copper Clad Laminate) Industry In-Depth Research Report> released by the Xinsi Industry Research Center, LCP-FCCL is mainly applied in fields such as communication systems, automotive electronics, and consumer electronics. In the communication systems sector, LCP-FCCL can be used in the manufacturing of 5G base station phased array antennas and the connection process of radio frequency front-end modules. Benefiting from national policy support and growing application demand, the construction pace of 5G base stations in China continues to accelerate. According to statistics from the Ministry of Industry and Information Technology, as of the end of December 2025, China had built 4.838 million 5G base stations. Against this backdrop, the development trend of the LCP-FCCL industry will continue to improve.

Major global LCP-FCCL manufacturers include Nippon Steel and Kuraray. Domestically, Junchitong, Shengyi Technology, and Sunway Communication are key participants in China's LCP-FCCL market. Junchitong is actively advancing the construction of an LCP-FCCL production project, which will have an annual production capacity of 30 million square meters upon completion.

An industry analyst from Xinsi stated that LCP-FCCL offers excellent performance and, as a flexible copper clad laminate, holds immense application potential in the 5G communication field. With the gradual release of market demand in the future, the development pace of China's LCP-FCCL industry is expected to accelerate. The global LCP-FCCL market is primarily concentrated in Japan, and China's demand is highly dependent on imports. It is expected that, over the next period, with technological advancements, the market share of domestically produced LCP-FCCL in China is likely to increase.
