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
I recently finished my PCB design files and had to release to manufacturer for order production, but I am really worry about file confidentiality leaking. How can I in this case?
I recently purchased LEDs on ebay that were supposed to come attached to star PCB (as a heat sink). The items I received are just the LEDs (no PCB). They are listed as 3W LEDs, with a forward voltage of 3.0-3.4V, and current at 700mA.Will I damage/destroy the LEDs if I use them without a heat sink? If not, what is the best way to mount these to preserve their life during operation?
As we all know, flex PBC is flexible. I am curious about the reliability of vias in it. Is it easy to break?
