Default Are any of you soldering pros?

I need to re-solder this QFN chip on this laptop board. It seems easy but I dont have the necessary equipment. I have a SMD workstation which I could probably use but its a bit overkill for what i need. I could use my iron, but its too small for my magnifying glasses for me to comfortably do it, and I dont have a small enough knife tip which would make it easier.

Its a small chip, about 10mm x 10mm. Anyone want to tackle this for me, I have money of course.

Dont laugh when you read this....have you tried putting the board in an oven for a while...get it hot enough for the solder to melt. I have repaired about a dozen laptops that had bad solder connections on chips on the main board...and they all worked when I got done.

That would probably work, but I need to replace the solder, not just fix the joint. The solder job is cheap china labor and just needs to be replaced to fix it long term. Thats the going fix at least. I plan on adding a copper shim to it to help fix it long term next time.

I soldered my stereo harness on the truck and it took everything I had to not throw the harness in the trash and stick the stock head unit back in.

I used to have the tools and the steady hand to do such work.

However these days, if it doesn't involve a decent sized wire and a generous amount of wiggle room I'd just screw it up.

lol

I fixed it using my smd rework machine, but it fucked up... again... I'm just going to buy a new laptop. This thing is repairable and its a shame because even though its a 2012 it was the top of the line model back then and is still extremely usable even for someone like me.

They won't fix it at an Apple store?

lmfao their fix is to put a piece of rubber on it so it puts pressure on the chip so the solder is doesnt break. Its the biggest fucking bullshit.

The real fix is to remove all the solder and replace it but its too much of a hassle for me to really care about.

I tried and tried to like the current MacBook, but man that touchbar is stupid. I'm ok with advancement, but putting the esc on the touch bar was a bad move. If they would have kept the function keys row and put the touchbar above it, it wouldnt have been so bad. I kinda like that dual display asus, that makes the touchpad a 1080p tiny monitor. That would have been amazing.

So i'm back to square one. I shipped my logic board off to a guy that can repair it for me. Its kinda crazy that my mid-2012 macbook pro is still completely viable as a main computer. I also have a 2012 MacBook Air that is still perfectly fast and only has 4GB of ram in it.

I looked at some PC laptops, but as with the macbook, they all had one or more glaring flaws in it that wouldn't net me more value than my current MacBook Pro if it were fixed.

Many times that turns out to be a temporary fix that won't work twice. Unfortunately. Learned it the hard way. Also a reason I won't buy used graphics cards off of ebay anymore. I haven't had one die on me (yet) but someone could do this, get it working, and quickly sell it. Like a used car. Then several months down the road it dies permanently on the next guy.
