Transfer Data From Dead Logic Board?

Hi all,

This is my first question, so please bear with me as I figure this out.

I have a iPad 2 CDMA (64GB) that had the battery swell up and explode (no one was injured other then the iPad itself), and it killed the screen, case, and the logic board. I bought the same model on eBay to try and swap the parts, and after I tested individual components with the new ones, I know that the logic board is dead, although I did get a relevant current draw when the power button is pressed. .

Since I know the logic board is dead, I used the iPad 2 Teardown Guide to locate the NAND flash chips, and attempt to transfer them to the new logic board. The only issue is that I ripped a few PCB pads during the de-soldering process of the original chip on the new logic board.

Is it possible to fix the ripped traces, or do I need another new logic board? Also, is this idea to recover the data even feasible? Since I haven't touched the original logic board with the data yet, those chips are still soldered on, so I obviously need a few tips on removing those as well.

Thanks in advance.
