Reassembly

Important

If you’re reinstalling the existing logic board, skip to reassembly step 15. If you’re installing a replacement logic board, continue to reassembly step 1.

Caution

If you’re installing a replacement logic board, the heat sink packaging screws and stiffeners must be transferred to the existing logic board before returning to Apple Service or the logic board may be damaged during shipping.

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

  2. Use the #00 Phillips screwdriver to remove the two #00 Phillips screws (923-07058) (1) from the heat sink on the replacement logic board.

    • Note: The two #00 Phillips screws are secured by two removable hex nuts (923-07059) (2) on the bottom of the logic board.

  3. Use the #00 Phillips screwdriver to fully loosen the six captive #00 Phillips screws (2) from the top stiffeners on the replacement logic board. Lift the top stiffeners off the replacement logic board and set them aside.
