🔧 Repair Overview
WiFi Antenna Repair is one of the most common repairs for iPhone 13. This repair involves replacing the damaged connectivity component with a new or refurbished part. The process typically takes 1-2 hours and requires moderate skill level.
What You'll Need
- Replacement connectivity part (OEM or aftermarket)
- Precision screwdriver set (Phillips #000 or pentalobe)
- Opening tools (plastic spudger, suction cup)
- Adhesive strips or glue
- Clean workspace with good lighting
Step-by-Step Process
Step 1: Disassemble the iPhone 13
Cover the cameras with protection stickers.
Remove the motherboard and split it.
Step 2: Test the Wi-Fi Circuits
Test the circuits related to the Wi-Fi module to verify that they are normal.
Step 3: Remove the NAND Chip
It is not possible to read the Wi-Fi serial number (SN) simply by connecting the iPhone to the programming software. Therefore, we will remove the NAND chip.
Heat the NAND chip evenly with a hot air gun at 420°C and airflow 80.
Pry the NAND chip up.
Apply some flux to the soldering pad of the NAND chip.
Remove the tins from the soldering pad using braid and a soldering iron.
Step 4: Use the Luban Programmer
Place the NAND chip in a Luban programmer.
Connect the programmer to a PC and open the programming software.
Click "Check Factory Data" to read the EcID of the iPhone.
Read the EcID from the NAND chip.
Step 5: Write New Wi-Fi SN Data
Place a new Wi-Fi module into the Luban programmer to write in the Wi-Fi SN.
Copy the EcID and select WiFi Operations on the navigation menu.
Paste the EcID and click "Check now."
Then click "Write now."
The Wi-Fi SN has been written into the new Wi-Fi module.
Step 6: Replace the Wi-Fi Module
Place the signal board onto a fixture.
Cover some other components with Kapton tape for protection.
Heat the Wi-Fi module with a hot air gun and use a pry knife to remove the edge adhesives.
Pry up the Wi-Fi module.
Apply some flux to the soldering pad of the Wi-Fi module.
Step 7: Solder the New Wi-Fi Module
Remove the tins from the soldering joints of the signal board.
Remove the tins from the soldering joints of the logic board.
Align the new Wi-Fi module carrying the SN to the soldering pad.
Solder the new Wi-Fi module with a hot air gun at 380°C and airflow 60.
Step 8: Solder the NAND Chip
Solder the NAND chip with a hot air gun at 380°C and airflow 60.
Step 9: Testing
Put the logic board and the signal board into a motherboard-layered test fixture.
Connect the iPhone 13 screen cable and the power cable.
Use a pair of tweezers to trigger the power-on.
The iPhone 13 should power on properly.
Go to settings to check if the Wi-Fi function toggle is resumed.
Step 10: Reassemble and Done
Solder the signal board with the logic board.
Assemble the iPhone 13 and test the Wi-Fi function.
Test and Wi-Fi should be restored and connected properly.
