Oral-B Black 7000 Motherboard Replacement

Introdução

The motherboard is the brain of the device. It connects all the components to the power supply and will need to be replaced if it is damaged or wears out due to use. Some steps in this procedure require desoldering connections. For a review of soldering techniques, check out this How to Solder Guide.

    • Use a soldering iron to melt the solder pad at the top of the motherboard, which attaches a battery electrode to the board. Remove the electrode by pulling it through the plastic housing after it has been desoldered from the board.

    • Repeat with the two solder pads on either side of the motherboard just above the black diamond-shaped component. The electrode foils can be pulled through the board from the back after the solder is melted.

    • Remove the motor housing from the plastic casing. This can be accomplished by using the nylon spudger to pry the motor housing out of the supporting structures.

    • The physical parts holding onto the motor are plastic knobs built into the plastic casing. Any manipulation done to the casing to remove the motor should be done within reason so that the casing is able to be reused.
