Flex at extended Temperatures (say 77 to ~400 K.)
I've been wanting to make a temperature sensor that is a little SMD transistor on pcb. I was thinking thin G10. But putting it on a piece of flex might be better. With G10 I was picturing soldering one lead to the pcb, with two little flying leads for the other terminals. So that thermal expansion/contraction wouldn't break the joint. With flex can I just solder it all? That would be nice!
I'll have to contact Allflexinc? (the first hit on google for "Flex circuit board") or is there some place better?
