Hi guys,
I need some advice here. I've been asked to design a board that has a temperature range from -40 degrees C to 150 degrees C.
I was thinking of using FR4 TG170 but wasn't able to find any information if this material can go down to -40 degrees C.

Thanks,
Adrian
 

FR4
https://en.wikipedia.org/wiki/FR-4

FR-4 (or FR4) is a grade designation assigned to glass-reinforced epoxy laminate sheets, tubes, rods and printed circuit boards (PCB). FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).


Maybe this can help:

There are many available options. Consider this for example, rated to handle down to -96 Celsius : **broken link removed**

You can also contact any manufacturer of the standard varieties and ask them for a quick recommendation.
It may also be possible to simply calculate if it will work for your application based on the relevant specifications of the board at hand: IE the coefficient of thermal expansion etc etc etc.

Good luck!
