iPhone 8 Wi-Fi Diversity Antenna Replacement

你所需要的

  1. iPhone 8 Wi-Fi Diversity Antenna Replacement, Remove the pentalobe screws: 步骤 1 中的图像 1,1
    • Before you begin, discharge your iPhone battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Power off your iPhone before beginning disassembly.

    • Remove the two 3.5 mm pentalobe screws on the bottom edge of the iPhone.

    • Opening the iPhone's display will compromise its waterproof seals. Have replacement seals ready before you proceed past this step, or take care to avoid liquid exposure if you reassemble your iPhone without replacing the seals.

  2. iPhone 8 Wi-Fi Diversity Antenna Replacement, Anti-Clamp instructions: 步骤 2 中的图像 1,3 iPhone 8 Wi-Fi Diversity Antenna Replacement, Anti-Clamp instructions: 步骤 2 中的图像 2,3 iPhone 8 Wi-Fi Diversity Antenna Replacement, Anti-Clamp instructions: 步骤 2 中的图像 3,3
    在这个步骤中使用的工具:
    Anti-Clamp

    • The next three steps demonstrate the Anti-Clamp, a tool we designed to make the opening procedure easier. If you aren't using the Anti-Clamp, skip down three steps for an alternate method.

    • For complete instructions on how to use the Anti-Clamp, check out this guide.

    • Pull the blue handle backwards to unlock the Anti-Clamp's arms.

    • Slide the arms over either the left or right edge of your iPhone.

    • Position the suction cups near the bottom edge of the iPhone just above the home button—one on the front, and one on the back.

    • Squeeze the cups together to apply suction to the desired area.

    • If you find that the surface of your iPhone is too slippery for the Anti-Clamp to hold onto, you can use tape to create a grippier surface.

    • Pull the blue handle forwards to lock the arms.

    • Turn the handle clockwise 360 degrees or until the cups start to stretch.

    • Make sure the suction cups remain aligned with each other. If they begin to slip out of alignment, loosen the suction cups slightly and realign the arms.

    • Heat an iOpener and thread it through the arms of the Anti-Clamp.

    • You can also use a hair dryer, heat gun, or hot plate—but extreme heat can damage the display and/or internal battery, so proceed with care.

    • Fold the iOpener so it lays on the bottom edge of the iPhone.

    • Wait one minute to give the adhesive a chance to release and present an opening gap.

    • Insert an opening pick into the gap.

    • If the Anti-Clamp doesn't create a sufficient gap, apply more heat to the area and rotate the handle a quarter turn.

    • Don't crank more than a quarter turn at a time, and wait one minute between turns. Let the Anti-Clamp and time do the work for you.

    • Skip the next three steps.

  5. iPhone 8 Wi-Fi Diversity Antenna Replacement, Heat the display: 步骤 5 中的图像 1,1
    • The next three steps show how to separate the screen using a suction cup.

    • Heating the lower edge of the iPhone will help soften the adhesive securing the display, making it easier to open.

    • Use a hairdryer or prepare an iOpener and apply it to the lower edge of the phone for about 90 seconds in order to soften up the adhesive underneath.

  6. iPhone 8 Wi-Fi Diversity Antenna Replacement, Separate the display: 步骤 6 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement, Separate the display: 步骤 6 中的图像 2,2
    • Apply a suction cup to the lower half of the front panel, just above the home button.

    • Be sure the suction cup does not overlap with the home button, as this will prevent a seal from forming between the suction cup and front glass.

  7. iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 7 中的图像 1,3 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 7 中的图像 2,3 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 7 中的图像 3,3
    • Pull up on the suction cup with firm, constant pressure to create a slight gap between the screen and the frame.

    • Insert an opening pick into the gap.

    • The watertight adhesive holding the screen in place is very strong; creating this initial gap takes a significant amount of force. If you're having a hard time opening a gap, apply more heat, and gently rock the screen up and down to weaken the adhesive until you create enough of a gap to insert your tool.

    • Slide the opening pick up the left edge of the phone starting at the lower edge and moving towards the volume control buttons and silent switch, breaking up the adhesive holding the display in place.

    • Stop near the top left corner of the display.

    • Do not try to pry the top edge of the display away from the rear case, as it is held in place by plastic clips that may break.

  9. iPhone 8 Wi-Fi Diversity Antenna Replacement, Screen information: 步骤 9 中的图像 1,1
    • There are delicate cables along the right edge of your iPhone. Don't insert your pick here, as you may damage the cables.

    • Re-insert your tool at the lower right corner of the iPhone, and slide it around the corner and up the right side of the phone to separate the adhesive.

    • Don't insert your pick more than 3 mm, as you may damage the display cables.

  11. iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 11 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 11 中的图像 2,2
    • Gently pull up on the suction cup to lift up the bottom edge of the display.

    • Do not raise the display more than 15º or you'll risk straining or tearing the ribbon cables connecting the display.

    • Pull on the small nub on the suction cup to remove it from the front panel.

  12. iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 12 中的图像 1,3 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 12 中的图像 2,3 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 12 中的图像 3,3
    • Slide an opening pick underneath the display around the top left corner and along the top edge of the phone to loosen the last of the adhesive.

  13. iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 13 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 13 中的图像 2,2
    • Slide the display assembly slightly down (away from the top edge of the phone) to disengage the clips holding it to the rear case.

    • Open the iPhone by swinging the display up from the left side, like the back cover of a book.

    • Don't try to fully separate the display yet, as several fragile ribbon cables still connect it to the iPhone's logic board.

    • Lean the display against something to keep it propped up while you're working on the phone.

  15. iPhone 8 Wi-Fi Diversity Antenna Replacement, Disconnect the battery: 步骤 15 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement, Disconnect the battery: 步骤 15 中的图像 2,2

    • Remove four Phillips screws securing the lower display cable bracket to the logic board, of the following lengths:

    • Two 1.3 mm screws

    • Two 2.8 mm screws

    • Throughout this guide, keep careful track of your screws so that each one goes back where it came from during reassembly. Installing a screw in the wrong place can cause permanent damage.

    • Remove the bracket.

  16. iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 16 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement: 步骤 16 中的图像 2,2
    • Use the point of a spudger to pry the battery connector out of its socket in the logic board.

    • Bend the battery connector cable slightly away from the logic board to prevent it from accidentally making contact with the socket and providing power to the phone during your repair.

  17. iPhone 8 Wi-Fi Diversity Antenna Replacement, Disconnect the display and digitizer: 步骤 17 中的图像 1,2 iPhone 8 Wi-Fi Diversity Antenna Replacement, Disconnect the display and digitizer: 步骤 17 中的图像 2,2

Hello, The power of my iphone 8 plus other products is lower than the mains and wifi. When I dismantle the product in question, there is no change. Which product should change. The reason is that when I hold the top part of the phone the wifi and mains power is falling more and more.

the two Phillips screws securing the bracket above the Taptic Engine won’t come out what do I do?

Hi Donnell,

Are the screws stripped or stuck? If they’re stripped, you can try some tips here.

I’ve tested all networks on a phone without this antenna and it seems to work just fine.

What does the absence of this part actually entail?

Smeargle - 回复

The diversity antenna is basically an additional antenna which helps improve the Wi-Fi reliability and quality. Wireless functions should work without it, but this additional antenna can help in congested urban environments.
