Is there a way to determine the die size and thickness. These number seam to have major effects on the life predictions of the IC.

The most accurate way to determine the die size and thickness for a given part is to examine the manufacturer data sheet for that part. Of course, once you've found the correct data, you can save a lot of time in the future by storing that data in the Sherlock Part Database for the specific part so that it will be available the next time you use that part.

To assist users, Sherlock makes "educated guesses" of the die size and thickness for all BGA, QFN and leaded SMT packages based on the package dimensions. Although such guesses are usually close enough for preliminary analysis purposes, you should always verify data correctness before performing a final analysis run.
