6. the method for electronic product burn-in test according to claim 5, it is characterized in that: the current value acquisition process in described step e is as follows: when detecting after the interruption generation of electric current, enter interruption, preserve the last level duration and the value of counter is removed, then restart timer conter, record accurately the duration of current level, exit the arrival of waiting for that interrupt next time.
