On September 28, 2022, China's leading LCP manufacturer, NJBD Advanced Materials Technology Corporation, announced:
The company will invest 1 billion yuan to build a new LCP film production line for 5G communication high-frequency transmission.
LCP molecules have strong rigidity, regular arrangement, and easy orientation of molecular chains. After film formation, it is easy to break the film under the force in the broad width (TD) direction, so the film preparation technology is high.
The company adopts the extrusion process route and independently develops the "high-precision melt extrusion+stretching technology" to solve the problem of different tensile strength in all directions during the preparation of LCP film, and research and develop LCP film materials with ultra-thin and thickness error to meet the market demand. At the same time, the 5G high frequency transmission LCP film prepared by this process has high temperature resistance, high strength and high mode, low dielectric loss and other characteristics, and has important application value in the 5G communication field.
The LCP resin is processed to obtain LCP film, and the LCP film is coated with copper by the FCCL manufacturer to obtain FCCL. The softboard enterprise processes the FCCL into FPC, and finally it is integrated by the module enterprise and sold to the terminal handset manufacturer.
The industry chain of 5G communication high frequency signal transmission LCP film industry is mainly composed of upstream raw material film level LCP material suppliers, LCP film manufacturers and downstream LCPFCCL manufacturers.
With the gradual maturity of 5G technology and the acceleration of global commercial layout, the market demand for LCP films used for 5G communication high-frequency signal transmission has grown rapidly.
LCP film has high requirements for the performance of LCP resin materials. Currently, few resin suppliers can mass produce LCP films for antenna modules. High end film grade resins are mainly concentrated in American and Japanese enterprises such as Baoli, Celanese and Sumitomo.
The company has cooperated with LCP resin material suppliers such as Poly plastics, Celanese and Sumitomo for many years.
