Tools and Materials Needed:

1. Replacement charging IC compatible with iPad Air.
2. Microsoldering iron with fine tips.
3. Hot air rework station.
4. Soldering flux.
5. Solder wick or desoldering braid.
6. Tweezers.
7. Magnifying glass or microscope for precision work.
8. Isopropyl alcohol and a brush.
9. ESD-safe workplace and wrist strap.

Procedure:

1. Prepare Your Workspace:
• Ensure you're working in an electrostatic discharge (ESD)-safe environment to prevent damage to electronic components.
2. Disconnect Power:
• Power off the iPad and disconnect it from any power source.
3. Disassemble the iPad:
• Follow a disassembly guide specific to your iPad Air model to expose the logic board.
4. Locate the Charging IC:
• Identify the charging IC on the logic board. It is typically located near the charging port.
5. Apply Soldering Flux:
• Apply soldering flux to the charging IC and the surrounding components. This helps in soldering and desoldering.
6. Desolder the Old Charging IC:
• Use the hot air rework station and microsoldering iron to carefully desolder the old charging IC. Use solder wick to clean up any remaining solder.
7. Clean the Area:
• Clean the area around the charging IC with isopropyl alcohol and a brush.
8. Place the New Charging IC:
• Carefully place the new charging IC in the correct orientation. Ensure proper alignment.
9. Solder the New Charging IC:
• Use the hot air rework station and microsoldering iron to solder the new charging IC onto the logic board. Be precise to avoid damage to nearby components.
10. Inspect Your Work:
• Inspect the solder joints under a magnifying glass or microscope to ensure they are clean and free of defects.
11. Reassemble the iPad:
• Put the iPad back together in the reverse order of disassembly.
12. Test the Charging Functionality:
• Connect the iPad to a power source and check if it charges properly.

If you are not confident in your microsoldering skills or if the issue persists after the replacement, it's advisable to seek assistance from a professional technician or a reputable repair service. Microsoldering requires precision, and any mistakes could lead to further damage.
