Swollen motherboard after using heat gun

Hi there,

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.

Answer this question I have this problem too

Is this a good question?

El cheapo heat guns can and will destroy a logic board by overheating. Sadly your logic board is gone. You’ll need to get a new one.

What you need is a proper rework station to do it right. These have temp & air flow controls to prevent this from happening.
