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.
Echter, 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-ontwerp
Our brand was focused on common electronic product with single PCB. And this year, we plan to develop a smart range which may require multiple layer PCB. Want to know more about 2 laag PCB of 4 laag PCB.
I am designing a 2 layer PCB with components on both side of it. SMT components are one one side of PCB, but TH (door gat) components are on both sides. I need to understanding something mentioned by the supplier called primary and secondary sides.
I noticed that most PCB and components on it are conformal coating. Is that a necessary process for all the PCB in other field? What are they for?
