iPhone 16 Pro Max Logic Board Installation

Hold the logic board so that the front sensor cable is close to its connector.

Align the front sensor cable connector carefully over its logic board socket.

Use the point of a spudger or your finger to press the connector until it clicks into place.

Gently bend all the loose press connectors out of the way so you can lay the logic board in place.

Lay the logic board in its recess.

Make sure the logic board rests in place against its screw posts. The posts will properly align the board to the display connector underneath it.

Use a standoff driver to install the four screws securing the logic board:

Two 4.5 mm‑long screws

One 3.4 mm‑long screw

One 4.2 mm‑long screw

Use your finger or a spudger to press and connect the three black press connectors onto the logic board.

Use your finger or a spudger to press and connect the seven silver press connectors onto the logic board.

Align the top edge of the earpiece speaker with the top edge of the frame.

Lay the earpiece speaker into its recess.

Install the six screws securing the earpiece speaker:

One 2.4 mm‑long Phillips screw

Three 1.3 mm‑long Phillips screws

One 1.6 mm‑long Phillips screw

One 3.3 mm‑long standoff screw

Use your finger or a spudger to press and connect the earpiece speaker and the mmWave connectors onto the logic board.
