Reassembly

Important: If you’re installing a replacement logic board, follow step 1. If you’re reinstalling the existing logic board, skip to step 2.

  1. Remove the existing Touch ID board and install a replacement Touch ID board.

  2. Hold the logic board by the edges. Rest the edge of the logic board against the antenna module. Then tilt the logic board down into the top case.

    • Caution: Ensure that no cables are caught under the logic board when you place it in the top case. Bending the cables under the board can damage the cables.
