Hi
You will get changes in conductivity at low temperatures
(definetely in the liquid helium range), this will ruin
your calculations. Furthermore some materials of which
your chip is build could start to phase change at low
temperatures. Ever seen what happens to standard
plastics put into liquid nitrogen? Due to the
surroundings my motherboard dual BP6 is seldomly
running under 60 C. So far no problems.
Kind Regards, Martijn
