The YFLEXⓇ Flexible Printed Circuit (FPC) Board, which adopts liquid crystal polymer (LCP) as the insulating substrate, has a low dielectric constant and low dielectric dissipation factor, thereby achieving exceedingly low transmission loss and ensuring excellent high-frequency characteristics. Furthermore, the YFLEXⓇ
FPC Board provides low hygroscopicity and superb dimensional stability, thus allowing ease of fine pattern processing and precise impedance matching. It has extremely high gas barrier properties, thus available in harsh environments. High-frequency substrates for millimeter band incorporating the YFLEXⓇ FPC Board satisfy the specified characteristics in high-temperature and high-humidity environments and places where high gas barrier performance is required. Furthermore, Yamaichi offers high-speed transmission cables that conform to Yamaichi-made connectors.
