iPad Air 3 Logic Board Replacement

Introduction

Follow this guide to remove or replace the logic board in a Wi-Fi only iPad Air 3. The cellular model will require disconnecting the upper cellular antennas.

For your safety, discharge the battery below 25% before disassembling your iPad. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

The logic board is paired to the Touch ID fingerprint sensor. If you replace the logic board, your Touch ID sensor will no longer work as a fingerprint sensor. It will still work as a home button.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

Ce dont vous avez besoin

  1. iPad Air 3 Logic Board Replacement, Prepare an iOpener: étape 1, image 1 de 1

    • Strong adhesive holds the screen in place. In order to separate it, you'll first need to heat and soften the adhesive using an iOpener, hair dryer, or heat gun.

    • You may need to reapply heat repeatedly throughout this process to prevent the adhesive from cooling and hardening.

    • Prepare an iOpener and place it on the bottom edge of the iPad's screen for about two minutes.

    • If your iPad's screen is badly cracked, wear skin and eye protection. Cover the screen with a smooth layer of clear packing tape to contain glass shards and help the suction cup adhere. Alternatively, use a strong piece of tape (such as duct tape) and fold it into a handle.

    • Place a suction cup next to the iPad's home button and press down to create a seal.

    • To get the most leverage, place the suction cup as close to the edge as possible without going past the edge of the display.

    • If you want to use the Anti-Clamp, a tool we designed to make the opening procedure easier, follow this guide.

    • Firmly pull up on the suction cup to create a small gap between the front panel and the rear case.

    • Don't pull too hard, or you may shatter the glass. If necessary, apply more heat to further soften the adhesive.

    • Once you've opened a sufficient gap, insert an opening pick into the gap.

    • Apply heat to the left edge of the iPad for about two minutes, or until it's slightly too hot to touch comfortably.

    • If necessary, re-heat your iOpener for a few seconds or until it's a bit too hot to touch. Be careful not to overheat the iOpener, or it may burst.

    • Insert a second opening pick at the bottom left corner of the iPad.

    • Slide the second opening pick along the left side of the display to separate the adhesive underneath.

    • Leave the opening pick inserted near the top left corner of the iPad to prevent the adhesive from re-sealing.

    • Gently twist the pick to separate the display assembly from the iPad.

    • Don't try to remove the display all the way yet! It is still connected to the iPad's motherboard.

    • If needed, apply more heat and/or cut any remaining adhesive that prevents the display from separating.

    • These photos show what the battery connector looks like underneath the logic board. Use these photos as a reference while you safely disconnect the battery.

    • Notice that the battery connector has cantilever springs on the logic board that press against the battery contact pads. Since both the logic board and battery are glued down, you'll need to slide something thin and flexible between the contact points to disconnect the battery.

  12. iPad Air 3 Logic Board Replacement, Disconnect the battery: étape 12, image 1 de 1

    • Be careful when you isolate the battery using a battery blocker. The battery contacts are easily bent or broken, resulting in irreversible damage.

    • To disconnect the battery, slide one prong of a battery blocker or the tip of an opening pick under the battery power connector to ensure the power circuit is interrupted.

    • Don't push the battery blocker underneath the connector with excessive force. If you're having trouble fitting the battery blocker underneath the logic board, you can try using a playing card to disconnect the battery instead.

    • The battery blocker or playing card ideally should slide under the logic board without encountering any blockages.

    • Leave the battery blocker in place as you work.

    • Remove the display assembly.

    • During reassembly, before installing a display, remove any remaining adhesive from the iPad, and clean the glued areas with high concentration isopropyl alcohol (90% or greater) and a lint-free cloth. This helps prep the iPad for fresh adhesive and ensures that it will bond properly.

    • If you plan to reinstall your existing display, remove any remaining adhesive from the back and clean the adhered areas with isopropyl alcohol.

    • Test your iPad's functions and install pre-cut adhesive strips to the back of the display using our display adhesive application guide before sealing it up.
