How to center middle and upper layer when reballing?

I bought iPhone X middle layer reballing stencil, but I can't find a way to center the boards when I'm putting them back together, if I heat the lower area of upper board and it sticks in place then the upper area lifts up, I think that the upper board has been a bit deformed due to the heat of a heat gun, can I use my flat heating platform to do that kind of job, it's capable of heating up to 300°C
