Do I need to clean camera IC on new OpenMV H7?

I am reading the hardware setup instructions http://docs.openmv.io/openmvcam/tutorial/hardware_setup.html, but they do not seem consistent with the construction of the H7. It looks like I first have to un-screw the two screws holding the camera module to the openmv board, then on the underside of the camera module un-screw the two screws holding the lens unit to the camera board. Is that correct?

Or perhaps its not necessary to clean camera IC on a new OpenMV H7?

thanks,
Chris

That is correct, but only if it needs cleaning. Our new manf. process makes sure the sensors are dust free.

Sometimes the sensor has dust on it. Most of the time not anymore.
