I'm finding this a real problem.
Sometimes the heatsink can be rotated slightly left and right like it is held on with something rubbery and will come off with a small amount of effort using a pair of pliers.
But others are stuck on like the heatsink is a bonded part of the BGA.
I've been practicing on scrap boards and on occasion have ripped the BGA off the PCB with the heatsink still firmly attached.
Heating them up with the hot air station does not help at all. I did see a video of someone using dental floss to remove the heatsink. I didn't have any so I did try with some of the wire you use to separate mobile phone screens (like cheese wire) but it did not help in the slightest
So how do I reliably remove the heatsink when it is held on with that rock hard concrete stuff?
