The features of high frequency PCB.
1. DK should be small and stable enough, usually the smaller the better, high DK may lead to signal transmission delay.
2. DF should be small, which mainly affect quality of signal transmission, the smaller DF could make smaller signal wastage accordingly.

The features of high frequency PCB:
1. Water absorptivity must be low, high water absorptivity will affect DK and DF when in the wet environment.
2. Heat resisting property, chemistry resisting, impact endurance, peel off resisting must be good.

Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom.
https://bit.ly/2Ew1hJT

Each layer of rigid-flex circuit are electrically interconnected by plated through holes (PTH), which is different from a flexible circuit with FR4/PI stiffener on top or bottom of flex circuit only by the means of preventive or thermal sensitive adhesive only, no PTH.
