Rigid and flex board assembly
We have some boards disconnected in transition zone: between rigid and flex segments. This happens during an assembly process. What is recommended to add to manufacture process in order to strengthen the area?

It seems like you are stating that you are having tearing of the flex circuit at the interface with the rigid board? And this is happening during manufacturing? During reflow, handling, or testing?
It would seem that this problem could be handled quite simply by ensuring good carrier design. Is there more to this that I’m missing?
Feel free to contact me directly with more details.
