Rigid-flex printed circuit boards directly combine the strengths of flexible and rigid printed circuit boards. This combination of technologies presents the user with a variety of advantages especially in terms of cost, signal transmission, assembly, stability,  overall size and weight, and reliability (due to there being fewer required interface connections).
