What are the FPC Stiffener Materials
Why should FPC be stiffened? Because the FPC itself is only flexible, and the application scenarios of individual FPC are different, in order to meet the use requirements, it is necessary to increase a certain thickness and rigidity in the designated position. The main purpose is to improve the strength of the FPC plug-in part; or to solve the local flexibility of the FPC, to facilitate the overall assembly of the product. Generally, the materials used for FPC stiffener need to meet the requirements of high and low temperature resistance, acid and alkali resistance, corrosion resistance, etc. So what are the FPC stiffener materials? 1. PI As a special engineering material, PI has been widely used in aviation, aerospace, microelectronics, nano, liquid crystal, separation membrane, laser and other fields. It is resistant to high and low temperatures and flame retardant. PI protective film or PI stiffener film is mainly used in FPC stiffener....
