Originally posted by hcarvalhoalves Flex circuits are the weak link on electonics because they innevitably wear out with use. Swivel screens on handy-cams, notebook lids, flip cellphones, etc. all those fail first at the flex board component. So much so that you often don't have trouble finding spare flex circuits on the market or having it fixed at a repair shop, there's a demand for it.
I understand the rationale. I was asking for evidence. That's a different thing entirely.
It also misses the point that if something is worthwhile, it may be worth risking as a point of failure. For example: shutters all fail inevitably, but we risk that and judge the life of the product based on it, The response is definitively not "I won't buy that because the shutter could fail." Because that is a partial analysis that takes into account only the negative side of the balance sheet.
But I won't belabour the point further. Some things, apparently, I am unable to explain to certain readers' satisfaction.
