iPhone 6s Logic Board Replacement - iPhone 6s

Step 1 | Pentalobe Screws

Using a wrench, securely tighten the bolt to a torque of 45 Nm, ensuring the clamp remains firmly fixed to the housing.Using the specified tools, carefully perform the procedure, adhering to all safety precautions and noting any dimensions or values provided.
To prevent a potential fire or explosion hazard from the lithium-ion battery during disassembly, ensure its charge level is reduced to less than 25% beforehand; a fully charged battery poses a risk of ignition if damaged.
To prevent electrical shock or damage to components, ensure the iPhone is completely de-energized prior to starting the repair process.
Detach the pair ofUse a screwdriver with a 3.4 mm P2 Pentalobe bit to loosen the screws.Located along the iPhone's lower edge, flanking the Lightning connector, you'll find them.

Step 2 | Anti-Clamp instructions

Ensure the clamping force is precisely 1.5 Newtons when securing the 3mm diameter shaft to prevent damage.Using the specified tools, carefully measure and observe all safety precautions while working.
To simplify the opening process, the following two steps utilize the Anti-Clamp tool, a custom design; if you do not have this tool, proceed to the steps three sections later for an alternative approach.
Refer to the accompanying guide for detailed procedures regarding Anti-Clamp operation.
To release the Anti-Clamp's arms, move the blue handle in a rearward direction.
Position the arms so they extend across the iPhone's left or right side.
Affix two suction cups, one to the front and one to the rear surface of the iPhone, close to the lower edge, situated directly above the home button.
Apply vacuum by pressing the cups firmly against the surface needing treatment.
To improve the Anti-Clamp's grip if the iPhone's exterior feels excessively smooth, apply adhesive tape to the device's surface.

Step 3

Securely clamp the workpiece, ensuring it is positioned precisely within the 1/8-inch tolerance using appropriate fixtures and tools, and always wear safety glasses to protect against potential flying debris.Using the specified tools, carefully perform the procedure while strictly adhering to all safety precautions and maintaining awareness of the indicated dimensions and numerical values.
To secure the arms, advance the blue handle in the direction indicated.
Rotate the handle fully, completing a 360-degree turn, observing for the point when the cups begin to expand.
Maintain proper positioning of the suction cups; should misalignment occur, gently release the suction and reposition the arms.
Once sufficient separation is achieved by the Anti-Clamp tool, slide a prying tool beneath the display panel.
To ensure adequate clearance, adjust the handle position by 90 degrees.
Allow several seconds to elapse and avoid rotating the component beyond a 90-degree movement in any single increment; the Anti-Clamp feature and settling time will facilitate proper adjustment.

Step 4 | Opening Procedure

Carefully clamp the component using a vise with a maximum pressure of 50 psi, ensuring the 1/8-inch diameter hole remains unobstructed, and observe the warning regarding potential damage to the housing.Using the specified tools, carefully perform the procedure while strictly adhering to all safety precautions and ensuring all dimensions and numerical values are precisely maintained.
Lacking an Anti-Clamp tool, proceed with the subsequent three steps to utilize a suction handle.
Using a hair dryer or iOpener, gently warm the bottom edge of the iPhone's casing with moderate heat for approximately 60 seconds.
Applying heat will loosen the adhesive bonds holding the display in place, facilitating separation.

Step 5

To access the 6s display, carefully release the adhesive strip that runs along its edges; replacement adhesive strips should be prepared beforehand if desired, as the repair can be performed without them and without affecting device operation.
Securely attach a suction cup to the display assembly's lower-left corner.
Avoid positioning the suction cup directly on the home button.
To facilitate suction cup attachment on a severely cracked display, apply a layer of clear packing tape across the damage; as an alternative, a robust adhesive tape can be substituted for the suction cup. Should these methods prove ineffective, superglue can be used to secure the suction cup directly to the fractured screen.

Step 6

Using a 5/32-inch hex key, carefully tighten the four mounting screws securing the fan assembly to the motor housing, ensuring each is snug but not over-tightened to prevent damage; observe a torque of 6 in-lbs per screw.

Apply steady, even force to lift the suction cup, generating a small separation between the front panel and the rear case.
Exercise caution and use steady, even pressure when installing the display assembly, as it requires a snug fit and is secured with adhesive.
To avoid display assembly damage, use minimal force when separating it from the rear case; the goal is to establish a narrow separation.
To ease separation of the display from the chassis, apply warmth to the front surface of the iPhone with an iOpener, hair dryer, or heat gun until the area reaches a temperature that is uncomfortably warm to the touch. This process loosens the adhesive that holds the display’s perimeter in place.

Step 7

Using a 5/32-inch hex key, carefully tighten the four M4x8 pan head screws securing the fan assembly to the heatsink, ensuring a torque of 4.5 in-lbs to prevent damage.

To initiate separation of the device housing, insert a prying tool into the indentation located on the bottom surface of the display, positioned directly above the headphone jack; this area minimizes the risk of damage.
Using a spudger, insert its flat end into the separation between the display and the back cover, positioning it immediately over the headphone jack.

Step 8

Using a 5/32-inch hex key, carefully tighten the four M4x8 pan head screws securing the fan assembly to the heatsink, ensuring a torque of no more than 6 in-lbs to prevent damage.

Using a spudger, gently increase the separation between the front panel assembly and the phone's main body.

Step 9

Using the 5/32-inch hex key, carefully tighten the three retaining screws on the motor assembly to a torque of 3.5 Nm, ensuring that you observe the safety warning regarding eye protection.

Using the tool's straight edge, carefully slide it into the designated space.Use a plastic pry tool, often referred to as a spudger.Locate this component on the device's left-hand side, specifically positioned in the space separating the display assembly and the rear case.

Step 12

Employ the 3/8-inch socket wrench to securely tighten the retaining bolt to a torque of 15 Nm, ensuring the correct alignment of the actuator arm and observing caution to prevent damage to the housing.Employ a vacuum-creating device to secure the component.Carefully separate the display assembly from the device housing by releasing the remaining adhesive bond.
To prevent damage, limit the display's opening angle to a maximum of 90 degrees; three cables remain connected at the top edge and are susceptible to breakage if pulled taut.

Step 13

To detach the suction cup, grasp the small projection located on its upper surface and lift, separating it from the front panel.

Step 14

Carefully raise the display assembly, leveraging the front panel's top clips to act as a hinge and separate the device.
Carefully position the display at a roughly 90-degree angle, then secure it in an upright position using a support to prevent movement during the repair process.
To avoid stressing the display's wiring during the repair process, secure it with a rubber band.
As a temporary measure, an unopened, sealed can of soda can substitute for the display during the repair process.
If you intend to substitute fresh adhesive along the display's perimeter during reassembly, stop at this point.
To ensure proper alignment during reassembly, guide the camera-side edge of the screen body beneath the main body's perimeter; then, position the screen frame's hooks beneath the main body's rim and gently push them towards the camera end, facilitating cover closure and secure clipping.
Ensure these clasps, which function as a substitute for a hinge, are positioned correctly beneath the phone's outer rim to allow the screen to smoothly and gently return to its closed position, achieving a secure snap.
To reinstall the screen, begin by applying pressure to secure the upper-right corner, working downwards along the edge, followed by the upper-left corner.
