After some hair-pulling experiences with co-planarity and 160-pin PQFP's, you have my sincere sympathy if you are trying to use this. We have instituted spec's that require our designers to pursue BGA packaging if the I/O is >120 pins, and if you can still influence the design I would recommend this. Good Luck!
