Conventional technologies such as Flexible Flat Cables and Flexible Printed Circuits (FFC/FPC) or micro-coaxial cables cannot cope with requirements for extremely high reliability and continuously increasing data transmission rates between internal printed circuit boards. The Y-FLEX technology of Yamaichi Electronics solves this problem. With the Y-FLEX high-speed FPC you can establish data rates of 56 Gbps (PAM4) over a cable length of 100 mm
