i had to use a pic16f873a along with a transformer(6A) in the same case(metal box).for controlling a set of relays(5A,12V).
the functional test was ok and it worked fine in the lab for 4 days continously but when it is released as aproduct we continously got complaints of "PIC hangs".
when it is reset the system works fine again.
my question is would there be any interference in the working of PIC due to the magnectic field/or temperature(in lab we tested upto 60 degrees)/power fluctuations.
or what else may be the problem
pls help me
thanks in advance
