I aim to reattach a faulty pin on my Phenom II. My heat gun only has two temperature settings (750-1000°F) and I’m worried about overheating parts before I proceed.
Search results indicate CPUs employ various solder types, with the most heat-resistant options reaching around 200-250°C (400-500°F) for components like BGA/LGA pins. This temperature is significantly lower than the output of a typical heat gun. A broad-tip heat gun operating at at least 750°F would be challenging to target the repair area without causing additional damage. A standard soldering iron with a fine tip would perform much better.
What's the point of worrying about the temperature if you're not paying attention to doing it right? Just go ahead and use it. The CPU is already bad, so why care about your actions? Edited May 13, 2020 by wkdpaul
Typically, most circuits manage a brief heat spike up to around 300°C. I wouldn't exceed that point. If you're concerned, you can use an aluminum block to dissipate heat from the chip while still being able to solder the connections.
