iPad Air 2 Wi

I just finished this repair successfully. Don't force ANYTHING Find something, a steel plate, aluminum plate, a heat gun and heat the plates not the iPad. Then it does not over heat, it is even and does not get cool. That makes it really easy. I used a piece of 6" of channel beam and blew the heat in the channel, measuring the top with a laser thermometer (140F target) after step #37, it worked so much better. I lifted the battery w/o touching electronics, and logic board too. It was easy with separators from IFixIT and slabs from a milk carton.
I don't think anything was risky this way and should have used the beam for the 1-37 steps.
Thanks to all who contribute here.
