I'll sell you a chip for $100.

Problem is, it's about 0.4mm pitch blind mount and not likely to be seated successfully without a split vision system.

Also, fails are often more than one chip.  Haven't read the most recent parts of this thread, but the fails I've seen cascaded over multiple tiers of chips.

I'm not trying to talk you out of it, but I don't want complaints that my chip is bad just because you can't place it.

Or, if you're sure it's only one chip, have the whole top tier pulled off and use one of those.  If you don't adjust the pic you'll be running at 50mV overvolt for the remaining tiers..  not that big a deal
