Problem is, this is an upgrade to an existing product. Management is pushing for lowest possible cost, they are not willing to redesign any of the plastic parts, as that would cost money, while bitching design is taking too long. Also, it is tight ass corporate, so we are limited in suppliers. Nothing from china is accepted. Must be from EU. So here I am, complaining, of nothing available anywhere.
The only thing, that can barely fit is 9mm wide FFC cable. Wider not possible, less wide not favourable, do to it being "flimsy" in the flexible bend, that may lead to some mechanical issues.
Electrically, I need 7 conductors, so 8x1mm cable made sense to me. Nothing high current, some hundred mA tops in two conductors..
I also thought about using a half pitch (0.5 mm), but that seems to be more expensive (about 1.4 times for 10ckt 0.5mm pitch cable) than the coarser pitched stuff.
