Do not scratch the copper pads attached to the vibration motor. Doing so may affect its ability to function.

The black material on top of the vibration motor is easily damaged. Avoid scratching it with your tweezers.

Apply a few drops of high-concentration (90% or higher) isopropyl alcohol to the open space next to the vibration motor.

Wait one minute for the isopropyl alcohol to weaken the adhesive underneath the vibration motor.
