Apple iPhone SE (3rd generation) Repair

Apple-iPhone-SE-3rd-generation-Repair-2

Introduction

This manual includes technical instructions for replacing genuine Apple parts in iPhone and is intended for individual technicians with the knowledge, experience, and tools required to repair electronic devices.

Warranty Information
Damage caused by repairs performed outside of Apple or the Apple Authorized Service network is not covered by Apple’s warranty or AppleCare plans. Such damage may cause future repairs to be subject to out-of-warranty costs or render the device ineligible for future repairs by Apple or Apple Authorized Service Providers.

Tools and Parts

Hardware tools
Apple tools are designed to apply the appropriate heat, force, and torque during repairs, and to withstand high-volume professional use.

  • The display press applies the appropriate amount of pressure to secure new adhesive during display installation. The display press is used with a repair tray designed for the device’s specific dimensions.
  • The battery press applies the appropriate amount of pressure to secure new adhesive during battery installation. The battery press is used with a repair tray designed for the device’s specific dimensions.

Ordering tools and parts
You can learn how to order genuine Apple parts and tools at support.apple.com/self-service-repair. During the purchase process, enter the manual ID GPCNKY to indicate that you’ve read this manual in its entirety and agree that you have the knowledge and experience to perform your intended repair.

Software Tools
A System Configuration step may be required at the end of your repair. System Configuration is a post repair software tool that completes the repair for genuine Apple parts. Running System Configuration has a number of purposes that vary based on the part replaced.

What System Configuration does  

Why it’s important

Transfers factory calibration values Certain parts like displays, cameras, and ambient light sensors have calibration values that are customized to each individual part during manufacturing.

Transferring these values ensures maximum performance and quality after

a repair.

Links Secure Element and biometric authentication parts After repair of a logic board or a biometric authentication part (Touch ID or Face ID), linking the biometric sensors to the Secure Enclave on the logic board is required to ensure device security.
Ensures repair integrity After a hardware repair, software checks are performed to ensure repair integrity. Repair integrity means that a genuine Apple part has been correctly installed.
Assigns wireless region To comply with regional communications regulations, a wireless region must be assigned to your logic board.
Updates firmware Keeping firmware up to date ensures that the device has all the latest security
and performance features.

System Configuration requires a strong Wi-Fi network capable of 1.0 Mbps download and upload speeds, with less than 400 ms latency and less than 2% packet loss. Estimated data usage to run System Configuration is 6–22 MB. The device must be running the latest version of iOS and not a beta version. Learn how to initiate the System Configuration process at support.apple.com/self service-repair.

Alerts
Failure to follow alerts could result in fire, injury, data loss, or damage to the device, parts, or other property.

Battery Safety

How to set up a workspace for battery safety
Tools

  • Clean, dry, untreated sand (8-10 cups)
  • Sand container (wide-mouthed, quick pour, non breakable plastic container with a flip-top lid)
  • Heat-resistant gloves
  • Safety glasses with side shields
  • ESD-safe cleaning solution

Workspaces used to repair Apple devices should meet the following criteria:

  • Nonflammable and electrostatic discharge (ESD)-safe work bench
  • At least 2 feet away from paper and other combustible materials
  • Sand container within reach (2 feet) on both sides of the workspace, not above the workspace
  • Adequate ventilation

Warning

How to handle a battery thermal event
Act immediately if you notice any of the following signs of a battery thermal event:

  • The lithium-ion battery or a device that contains one begins to smoke or emit sparks or soot.
  • The battery pouch suddenly and quickly puffs out.
  • The lithium-ion battery or a device that contains one begins to emit hissing or popping sounds.

A battery thermal event is a rapid chemical chain reaction that occurs inside a battery cell. The energy stored in the battery is released suddenly, which can cause outgassing and fire. A battery thermal event can be triggered by physical damage to the battery, improper replacement or repair, or temperatures outside the battery’s operating range. Don’t use water or an ABC or carbon dioxide fire extinguisher on a battery thermal event or a device that is undergoing one. Water and ABC or carbon dioxide fire extinguishers won’t stop the reaction. Do smother the battery or device immediately with plenty of clean, dry sand. Dump the sand all at once. Timing is critical – the faster you pour all the sand, the sooner the reaction will be contained. Do contact local fire authorities if further assistance is needed. Do leave the room for 30 minutes after the reaction is contained. Ventilate the area. Don’t return until the area is clear of smoke. Do wait 30 minutes before touching the device. Wear the heat-resistant gloves and safety glasses with side shields to remove the device from the sand. Do wipe the affected area with water first. Then wipe the area with an ESD-safe cleaning solution. Do dispose of the damaged battery or device (including any debris removed from the sand) according to local environmental laws and guidelines.

How to handle batteries

Perform the following steps to discharge the battery:

  • Disconnect all external cables.
  • Remove all cases and covers.
  • Turn on the flashlight from the Lock Screen, in Control Center, or by asking Siri. Wait until the device has turned off and the flashlight is no longer illuminated.

Best Practices

To avoid noxious fumes or a battery thermal event, don’t puncture, strike, or crush a lithium-ion battery or a device that contains one.

  • Keep your workspace clear of foreign objects and sharp materials.
  • Be careful when using sharp tools near the battery.
  • Don’t leave loose screws, extra screws, or small parts inside the device.
  • Don’t use tools that conduct electricity.
  • Don’t throw or drop the battery.
  • Don’t expose the battery to excessive heat or sunlight, or temperatures outside the battery’s operating range.
  • Handle and dispose of waste batteries in accordance with local laws and regulations.

Broken Glass

Tools

  • Back protective cover
  • Cut-resistant gloves
  • Display protective cover
  • Safety glasses with side shields
  • Support frame
  • Vacuum cleaner

If the iPhone glass is broken, perform the following steps before you begin a repair:

  1. Put on safety glasses with side shields and the cut-resistant gloves.
  2. Use a vacuum cleaner to remove glass pieces from your workspace and the iPhone.
  3. Attach a protective cover to the broken glass to prevent injury or scattering of glass. Each protective cover has a release liner underneath. Slowly pull the release liner out from under the protective cover while pressing the cover onto the enclosure.
  4. Fold the release liner. Use the shiny side of the release liner to firmly press the protective cover onto the broken glass and smooth out any air bubbles.
  5. Wait at least 12 minutes for the bond between the protective cover and the glass to strengthen.
  6. If the back glass is broken, place the iPhone into the support frame.

Apple-iPhone-SE-3rd-generation-Repair-8

If the iPhone has any of the following conditions, stop the repair:

  • There’s no glass or insufficient glass for the protective cover to adhere to.
  • The protective cover doesn’t adhere to the iPhone.
  • The iPhone doesn’t fit in the support frame.

You can find a service option at support.apple.com/repair.

First Steps

Always perform the following steps before starting a repair:

  • Back up the iPhone.
  • Discharge the battery fully.
  • Turn off the iPhone.
  • Disconnect all cables.
  • Remove all cases and covers.
  • Clear and clean your workspace.
  • Put on an ESD wrist strap and attach it to a properly grounded ESD mat.

Be aware of the following while performing a repair:

  • The manual for this model may show images of other models, but the procedures are the same. Ensure that you use the correct tools for the model you’re repairing.
  • Take your time. Thoroughly read all instructions and alerts.
  • Magnetizing the torque drivers will make it easier to work with small screws.
  • The end of each flex cable must align with its connector. Press the end of each flex cable to its connector until it clicks to ensure that it’s secure.
