It's important to know what type of Hot air station you use, if you use Hakko 850 or similar put the handle grip of the heat on 4 o 4/5 and the handle grip of the air on 5 max 6. For Dome led you can use hair dryer and remove from where you put screw for making to make to him contact on the logic and not from under the display.
