BURN-IN SCREENING
Burn-in screening is an option available for the models
indicated in the Ordering Information table. Burn-in dura-
tion is 160 hours at the maximum specified grade operating
temperature (or equivalent combination of time and tem-
perature).
All units are tested after burn-in to ensure that grade speci-
fications are met. To order burn-in, add “–BI” to the base
model number.
