I just used an air gun to remove the heatsink from the motherboard and then blew on it for a long time before realizing something was wrong. When I checked the LCD screen, I found the temperature setting was too low. No wonder it took so long; I hadn't dared to set the temperature too high when I first started using it. After resetting the temperature, the solder paste quickly melted, and then it worked normally. Have you encountered similar problems during repairs?

I'll show you a picture


If the chip is dead, the most important thing is not to damage the board. Sometimes repairers use double-sided heating.

What type of motherboard you working on and what was the problem that makes you believe that these heatsinks are the problem? What issue are you trying to fix and how was it after the operation?
