The camera’s feature set - a 4 inch touch screen, image sensor, variable power (depending on operating mode) PCB, solenoid actuated mechanical shutter and a high zoom lens with accompanying motor control board - required a thermal solution that would ensure quality photographs and long product life.
Thermally, the most critical component was the image sensor, as its operating temperature directly affects the quality of the captured photographs. Keeping temperature deviations inside the camera body at or below the image sensor’s limit was the primary focus of the thermal solution.
Other PCB components, such as the high capacity battery and chip subcomponents also contributed to internal temperature increases. Exterior surface temperature (touch temperature) had to remain under target limits during all operating states of the camera.
