During reassembly:

If any rear camera conductive tape is still on the logic board, use tweezers to remove it.

Remove the replacement conductive tape from its plastic backing.

Carefully place the conductive tape so it connects the metal tab on the bottom right corner of the camera housing to the logic board.

Use the flat end of a spudger to firmly press the adhesive into place, securing it to the camera and logic board.

Remove the remaining liner.
