A Study of Impedance Control in Flexible Printed Circuit (FPC)

PublishTime：2022-10-29

● Ordinary, requirements for printed circuits are only to be connected correctly and to have enough electrical current capacity. If signals used inside of equipments are very low frequency, impedance control of circuit is not needed. Impedance control is needed only for long communication cables between equipments.
● When electrical circuits with high frequency signal are operated, impedance control is needed for not only communication cables but also printed circuits.
● Recently it is not rare that the high frequency signal (several hundreds MHz to several GHz) is used inside of equipment. In this case, the circuit should be considered as distributed constant circuit even if the circuit is very short. Therefore impedance control of circuit is needed on Printed Circuit Board.
● Based on the background described above, we have tried to control characteristic impedance of Flexible Printed Circuit (FPC) .
