  9. With the PCB removed in the previous steps, use the Spudger Tool to pry the Camera face from the Camera Body Pull the Camera face away from the Camera Body
    • With the PCB removed in the previous steps, use the Spudger Tool to pry the Camera face from the Camera Body

    • Pull the Camera face away from the Camera Body

  10. There are two more PCBs in the camera face assembly.  The Top PCB is held in place via a zero force insertion connector. A Spudger Tool can be used to remove the Top PCB by gently prying the Top PCB loose near the zero force insertion connector, and working around the outside of the Top PCB prying it loose further with the Spudger Tool

    • A Spudger Tool can be used to remove the Top PCB by gently prying the Top PCB loose near the zero force insertion connector, and working around the outside of the Top PCB prying it loose further with the Spudger Tool

    • The Siren/Speaker is also connected to the Top PCB and can be unplugged.

  11. The Top PCB has a Heatsink on it that can be removed with a Spudger or Dental Pick Tool The Heatsink is held in place with Thermally Conductive Adhesive Transfer Tape
    • The Top PCB has a Heatsink on it that can be removed with a Spudger or Dental Pick Tool

    • The Heatsink is held in place with Thermally Conductive Adhesive Transfer Tape

  12. Once the Heatsink has been removed, the Top PCB can be inspected.  The Top PCB has RF Shielding on both sides The RF Shielding can be removed using a Dental Pick Took Pro-tip, if the RF shielding has a small circle indention on it, there is a good chance the shield was snapped in place, and not soldered to the PCB, which makes it easier to remove
