Double-stacked Motherboard Repair Steps
There are 4 steps to repair the double-stacked motherboard as follows:
Step 1: Motherboard Separating
When repairing the logic board of the iPhone series before iPhone X, we can remove/solder components with the help of the Hot Air Gun. However, with the motherboards of iPhone X and later models being double-stacked, the Hot Air Gun fails to heat the third space PCB evenly due to the large range. Hereby we recommend this Specialized Heating platform for your double-stacked motherboard repair.

You will need the Motherboard Disassemble Platform Main Unit For iPhone – SS-T12A and Motherboard Disassemble Platform Heating Groove For iPhone X/XS/XS Max – T12A – X3.
The 3 in 1 Heating Platform For iPhone X/XS/XS Max is suitable for iPhone X/XS/XS Max motherboard separating, CPU and other components removing. The temperature range is 100-280℃.
Traditional Hot Air Gun features high requirements for temperature control. Therefore, any carelessness may result in solder joint falling-off or bridging that leads to not turning on of the motherboard or other issues.
Step 2: Diagnosing & Trouble Shooting
