A vehicular camera module includes a housing for mounting at a vehicular windshield, a processor printed circuit board (processor PCB) disposed in the housing, and an imager assembly. The imager assembly includes (i) a lens barrel accommodating a lens, (ii) an imager printed circuit board (imager PCB), and (iii) a flexible electrical ribbon cable that electrically connects the imager PCB to the processor PCB. An imager is disposed at a first side of the imager PCB. The imager PCB includes an imager portion at which the imager is disposed and attaching portions at respective outboard ends. At least one stress relieving portion is established at the imager PCB between the imager portion and each of the attaching portions. With the lens barrel received through an aperture of the housing, the attaching portions of the imager PCB are attached at the housing via respective fasteners.

A vehicular vision system includes a camera module having a housing that houses at least (i) electronic circuitry disposed at a main printed circuit board (PCB) and (ii) an imager assembly. The imager assembly includes an imaging array sensor, an imager PCB and a lens holder that includes an elongated lens barrel that houses at least one lens. Electronic circuitry is disposed at an upper side and at a lower side of the main PCB. Image data captured by the imaging array sensor is conveyed to electronic circuitry disposed at the main PCB. An electronic component of electronic circuitry disposed at the main PCB is in thermal conductivity with a thermal element, which is in thermal conductivity with a lower housing portion of the housing to enhance heat transfer from the electronic component to the lower housing portion of the camera housing.
