How does heat impact the signaling performance of unshielded ribbon/flexible flat cables?
Background: I'm modding a camera to improve thermal performance by adding thermal pads between the heatsink and the camera case. The thermal pads are not electrically conductive, but I'm puzzled as to why the manufacturer didn't do this in the first place. Given that there is direct contact between the primary cable (directly above box B) I don't think the cables are at risk of overheating. The lack of thermal pads in square A (where there is no cabling) suggests this is just cost optimizing.
