High-frequency flexible copper-clad laminate SRFP series
Product Introduction 
Flexible circuit board material is a flexible copper-clad laminated composite material, which is the processing substrate material for flexible circuit boards. It is mainly composed of high-performance insulating base materials polyimide/fluoropolymer composite materials and flexible metal copper foil (rolled copper foil or electrolytic copper foil), and is specially designed for high-speed digital and high-frequency flexible circuit applications.
Application Areas
Flexible printed circuit boards for high-speed digital and high-frequency circuits
