If you have an IC with broken pins near the die normally this chip is dead but if you have a CO2 laser cutter and a bit of time you might be able to laser away some of the die so you can access the internal chip traces. Have a look at ca.rstenpresser.de for some ideas.

“Since a few of the Pads already were delaminated I decided to do a repair instead of soldering in a new CPU. For a repair I would need to get rid of the expoxy mold to directly acces the pins of the leadframe. Initially I was thinking of using a ‘dreml’ tool to remove the exoxy, but watching the Uncaging Microchips talk at 31C3 taught me that using a CO2-Laser will also work.”
