Dear Technetters,
we have build PCB's with a commercial range processor (and a few other
components), and tried to have it work at -40°C.
of course, it failed, this could be predictable.
our concern is that the board failed too when tested during raising
temperature to +40°C (via a low temperature gradiant), because of several
dammaged components.
our R&D engineer is investigating to determine the cause of the failure, but
it brought me to the following question : is there any risk to destroy a
component when using it at a temperature lower than the lower limit ?
if yes, which process does dammage the component ?

thanks for sharing your experience

kind regards
