Technique:
①Use tweezers to clamp the position of the motherboard stud, and lift it up tentatively for the first time (note: you must not shake the tweezers left and right, you can stabilize the technique after many practice).
②Do not use too much force at this time, and pay attention to whether the bottom layer of iPhonex motherboard leaves the k85 soldering station (if you find that the bottom layer of iPhonex motherboard leaves the k85 soldering station at this time, it means that the tin point of the middle layer has not completely melted or the force is too strong).
③Confirm that the tin in the middle layer of the iPhone x motherboard is melted, and no resistance is felt when you lift it up. The bottom layer of the iPhone x motherboard does not leave the k85 soldering station, and then slowly separate the upper motherboard of the iPhone x, and shut down the k85 for a certain period of time. Download the iPhone X bottom board.
