I am attempting to replace the retimer chip. Even with my hot air station at its highest temp, the chip will not unsolder. Any suggestions?
Nigel, it is a cheap one from Amazon. I am even questioning if the iron is even getting hot enough. Can you recommend a reasonable system?

Are you adding flux around the chip? It helps transferring heat. Also it’s not just the chip that has to be hot enough to melt the solder it’s the board too. What temp are you using? 380-400 degrees c should be enough. Use a circular motion with the hot air around the chip and don’t just point it at the chip. It could take a while but take care not to overheat the board as it can warp.

Thank you for the advice. It appears that my hot air station temp is not correct. Changed to a gun and popped right off. Now if I can find R31 that blew off…All is good.
I will attempt to get it again. I had the heat at 500C. Big issue is I was blowing the caps and resistors off the board. Had what I thought was enough flux, but will keep everyone posted.
If its blowing parts off the board then your airflow is way too high. Turn it down to say 20 to 25% to start with. Also having a small nozzle on the gun will increase the airflow. If parts are moving around the chip then the board is definitely getting hot enough and the chip should also come off. Possibility the chip is burned to the board.
Thanks for the advice. It turns out the hot air station isn’t putting out enough heat. Used a heat gun and popped right off. Now just have to rework some caps and resistors
@lmccreery what station are you using?

I like equipment by atten. Not cheap but not expensive either. Never let me down to be honest. Google or ebay.

Thank you Nigel. I will look into it. Can you recommend the replacement for c20 and R31 on the Xbox one X system board? Located around the retimer chip.
