iPhone SE 2020 Wi-Fi Diversity Antenna Replacement

• As a preliminary precaution, ensure your iPhone's battery has been depleted to a level below 25% prior to commencing the repair process.A fully charged lithium-ion batteryposes a significant hazard, potentially igniting or undergoing explosive rupture if inadvertently damaged.
• Deactivate the iPhone's power supply by turning it off before you start disassembling it.
• Utilize a suitable tool to extract the pair of 3.5 mm pentalobe screws located along the iPhone's lower edge.
• Separating the iPhone's display assembly will irreversibly damage the integrated waterproof barriers; therefore, acquire replacement seals beforehand to prevent liquid ingress, or exercise extreme caution to prevent moisture exposure if you intend to reassemble the iPhone without new seals.

• To avoid potential harm to your device, ensure the opening pick isn't inserted beyond its intended depth; this procedure details how to mark the pick to safeguard against such damage.
• Determine the measurement of3 mmfrom the pick's leading edge and use a permanent marker to create a visible indicator on the opening pick.
• For added precision, consider marking the remaining corners of the pick with varying measurement values.
• As another option, affix a coin to the pick's shaft,3 mmaway from its tip.

The following three procedures illustrate the function of the Anti-Clamp tool, which was specifically engineered to simplify the initial opening process; should you choose not to utilize this tool, proceed past three steps to access an alternative approach.

Detailed instructions regarding the Anti-Clamp's operation can be found in a separate, dedicated guide.

• To release the locking mechanism, draw the blue handle in a rearward direction, which will disengage the Anti-Clamp's arms.
• Carefully position the arms across either the left or right side of your iPhone.
• Place the suction cups close to the lower edge of the iPhone, situated directly above the home button—one cup on the front surface and one on the rear surface.
• Apply pressure by compressing the cups together to create a secure vacuum seal on the intended area.
• Should the iPhone's surface prove excessively slick, preventing adequate adhesion by the Anti-Clamp, applying adhesive tape can provide a more textured surface for improved grip.

• To secure the arms, advance the blue handle in a forward direction.
• Rotate the handle in a clockwise direction,a full 360 degrees,or continue until the cups exhibit signs of deformation.
• Maintain the precise alignment of the suction cups; should they become misaligned, slightly release the suction cups and reposition the arms.

• Employ a heating device, such as aniOpenerto carefully maneuver it between the arms of theAnti-Clamp.
• Alternative heat sources, including hair dryers, heat guns, or hot plates, are acceptable; however, exercise caution as excessive temperatures can potentially harm the display assembly and/or the internal battery.
• Position theiOpenerin a manner that it rests along the lower edge of the iPhone’s casing.
• Allow a period of sixty seconds to pass, enabling the adhesive to soften and facilitating a separation.
• Introduce an opening tool into the newly formed separation.
• Should theAnti-Clamp fail to generate an adequate separation, increase the heat applied to the area and incrementally rotate the handle by ninety degrees.
• Avoid excessive rotation, limiting adjustments to ninety-degree increments, and pause for sixty seconds between each rotation to allow the adhesive to release.Anti-Clampand time are your primary tools for this process.

The following three procedures detail the process of detaching the display assembly with the aid of a suction cup.

Applying heat to the bottom edge of the iPhone will assist in loosening the adhesive bonds holding the display in place, which simplifies the separation process.

Employ a hairdryer, or alternatively prepare aniOpenerand apply it to the lower edge of the device for approximately 90 seconds to reduce the adhesive's tackiness.

Securely affix a suction cup to the bottom portion of the front panel, positioning it directly over the home button area.

Ensure the suction cup's surface remains clear of the home button's location, because contact will obstruct the creation of a complete bond between the suction device and the glass face.

Apply steady, consistent upward force to the suction cup to generate a small separation between the display assembly and the device's surrounding structure.

Carefully slide an opening tool into the newly formed space.

Due to the robust nature of the waterproof sealant securing the display, establishing this initial separation requires considerable effort; should you encounter difficulty, applying additional heat and gently oscillating the display upwards and downwards will help to reduce the adhesive's strength, allowing for sufficient separation to accommodate your tool.

• Begin separating the display assembly from the chassis by inserting a prying tool beneath the left edge, initiating the separation at the bottom and progressing upwards towards the volume controls and the silent switch, which will disrupt the adhesive bond securing the display.
• Cease the separation process in the vicinity of the upper-left corner of the display.
• Refrain from attempting to disengage the display's upper edge from the rear casing, because it is secured with fragile plastic clips that are susceptible to breakage.

Along the right side of your iPhone, you'll find sensitive wiring; avoid inserting any tools in this area to prevent potential cable damage.

• Carefully reposition your tool at the lower-right edge of the iPhone, then maneuver it along the corner and up the right-hand side to release the adhesive bond.
• Ensure your opening tool does not penetrate deeper than3 millimeters, to prevent potential harm to the delicate display cable connections.

• Carefully elevate the display's lower border by applying upward force to the suction cup.
• The display should not be raised beyond an angle of15 degreesas exceeding this limit could potentially damage or sever the flexible ribbon cables that link the display.
• Detach the suction cup from the front panel by grasping and pulling on the small protrusion located on its surface.

• Initiate the iPhone's disassembly process by pivoting the screen upwards, originating from the left edge, mimicking the action of opening a book's cover.
• Refrain from completely disconnecting the display at this stage, because multiple delicate ribbon cables remain attached, linking it to the iPhone's main circuit board.
• Secure the display in an upright position using a support to maintain access to the internal components during the repair.

• Specifically, two screws measure 1.3 millimeters in length.
• Additionally, two screws measure 2.8 millimeters in length.

• Employ the tip of a spudgerto carefully disengage the battery connector from its corresponding receptacle on the logic board.
• Gently deflect the battery connector cable slightly outward from the logic board's surface, ensuring it remains disconnected and avoids unintended electrical contact with the socket, which could inadvertently power the device during the repair process.

• Employ the tip of a spudgerto carefully disengage the lower display connector from its receptacle.
• For reattachment, apply pressure to one edge of the connector until a distinct click is heard, then repeat the process on the opposing edge; avoid applying pressure to the central portion. Even minor misalignment during reattachment can result in bending of the connector, potentially leading to irreversible damage.

• Employ the tip of a spudgerto carefully separate the connector of the lower display cable assembly from its socket.

• To detach the bracket that covers the front panel sensor assembly connector, eliminate the three screws, each measuring 1.3 mm in diameter, and utilizing a Phillips head.PhillipsThe bracket, now unsecured, can be taken away.
• Remove the bracket.

• Detach the display assembly from the device.
• If you intend to substitute the adhesive securing the display's perimeter during reassembly, halt the process at this stage.

• To detach the bracket positioned adjacent to the Taptic Engine, it is necessary to eliminate three fastening screws.
  One screw, specifically a 1.3 mm Y000 type, is required.
  A 2.7 mm Phillips head screw is also needed.
  Additionally, a 2.9 mm Phillips screw must be removed.

• Carefully insert a separating tool into the space between the antenna flex cable and the speaker's upper surface.
• Adhesive lightly secures this section of the flex cable; applying warmth, if needed, can facilitate separation.An iOpeneror a standard hair dryer can be utilized to reduce the adhesive's viscosity, ensuring a safer separation of the flex cable.

• Carefully leverage the tip of a spudger to lift and detach the diversity antenna flex cable from its connection on the logic board.

• To prevent the socket from moving, insert a thin opening pick beneath the antenna flex cable.
• Employ the tip of your spudger to lift and detach the antenna flex cable from its socket, maintaining socket stability with the opening pick.
• Re-establishing this connection presents a challenge; simplify the process by utilizing tweezers to secure the flex cable, ensuring proper connector alignment with its socket, subsequently applying even pressure directly downward on the connector’s surface with the spudger’s flat edge until a distinct click confirms secure engagement.

• Disconnect the Wi-Fi diversity antenna from its connection.
