MacBook Pro Early 2011 - baking logic board to fix graphic error
Hey guys, wondered if you could help me out here. So I just had that issue with my graphics card on my 20011 Macbook Pro where suddenly I got jagged lines and artifacts on the monitor and the Macbook would hang shortly after booting up. I then followed the instructions to reflow the graphics chip, baked the board for 8 min. at 200 C° in the oven and the Macbook came back to live, hooray!
Only one thing I noticed when I put the logic board back together was that the two small heat spreaders for the Intel BD82HM65 platform controller hub (Red) and Intel L051NB32 EFL controller (Blue) do not touch the surface of the chips but just sit there about 0.3 mm or so above.
I didn't really paid attention to that when I took them of, they where slightly sticking to the chips and there was quite a bit of thermal paste on them.
So I wonder ist it intentional for the heat spreaders to not touch the chips and is it sufficient in that case to just have a blob of thermal paste filling the tiny gap between heat spreader and chip? I was just worried that maybe the chips have sunken a litttle bit into the keyboard due to the solder becoming soft during the baking process in the oven? Did anyone noticed this before?
Is this a good question?
