I am new to hot air soldering. I need to remove one chip from the board. I have a hot air solder and I set the temperature to 350°C. I slowly started heating the chip, but the solder didn't melt. I heated it for about 5 minutes, but the solder still wouldn't melt. I increased the temperature to 450˚C and still nothing. After a while, the board started to change color, but the solder still didn't melt.
Fortunately, I'm testing it on old network switches to see how it works.
What am I doing wrong?
I've seen a lot of videos on youtube and everyone got the solder melted and the chip was easy to remove from the board.
