I'm wondering about the long term reliability of FFC connectors, especially in environments exposed to shock and vibration. It seems like everything with a display uses such connectors, which means they must be present and in use in automotive environments, at least in the user console, which is still exposed to shock, vibration and thermal cycling. One major concern is fretting. My Internet searching up to this point hasn't provided very much information.
Does anyone have any experience using these types of connectors in automotive / aerospace / military applications who can speak of the long term reliability? I think most people think of them as being flimsy, but from my experience they seem to make a very secure connection. Any feedback appreciated.
One thing I am aware of is that they are not meant for applications with multiple connect / disconnect cycles, but I'm speaking specifically about applications where the connectors will only be latched once, to connect boards together permanently inside a product enclosure.
