Swollen motherboard after using heat gun
I used a heat gun to replace the backlight IC on my Macbook Air.
I must have heated it too long or too strong, because at one point, the motherboard underneath started swelling. In total the "bubble" reached maybe 1 inch in diameter or so.
It quickly fell back, but everytime I would heat it again it would swell again.
The problem is that now, some connections are not happening. When I use my multimeter to test for continuity, at some point continuity is not there unless I press really hard on the board with my probe.
Is there a way I could fix that ? Has anyone encountered this before ?
The only idea I could come up with so far was to drill a hole, and use a bolt to compress the board. But I am afraid I will be drilling through a wire by doing so.
