What is usually done is that a stiffener is added to the area of the connector. The stiffener is usually FR4 (with no copper) glued/epoxied to the flex on the backside of the connector.
However, maybe the application results in minimal bending without stiffeners. What counts as acceptable is rather dependent on the particular parts, the application, and the required reliability and lifetime, so it’s not easy to quantify.

#PCB Design
Try to repair electronic sphygmomanometer now. It seems wires fell off from the flexible PCB, leaving trail on there. How do I solder them to the flex-PCB?
I am learning to design a multiple layer board for a medical device, and have a question about where the ground should place.
According to IPC-7351, the cathode should be on the left for a molded diode. However, when I use component wizard of my suppliers to create a diode, it places the cathode (K) on the right. Does it depend on the manufacturer? How does the assembly house know which way is correct?
