 ### Transmission line design on flex pcb
 Flex pcb has a very thin dielectric core for easy bending.
 - Thin dielectric means transmission line needs to be designed with extremely thin traces.
 - Calculations with a solid ground plane puts trace width at < 0.05mm which is not manufacturable.
 - Requires using a hatched ground plane to achieve target impedance at manufacturable 0.1mm trace width.
 - Hatched ground plane needs very careful design considerations and is not trivial to design.
