1. A camera module configured to mount at a receiving structure at an interior surface of a vehicle windshield of a vehicle equipped with a vehicular vision system, said camera module comprising:

  • a camera housing, a processing circuit board and an imager assembly;

    wherein said processing circuit board is accommodated in said camera housing;

    wherein said imager assembly comprises an imager, an imager circuit board, a lens holder and a lens;

    wherein said imager circuit board has a first surface and a second surface opposite said first surface;

    wherein said imager is established at said first surface of said imager circuit board;

    wherein said lens holder comprises a lens holding portion and an attaching portion;

    wherein said lens holding portion of said lens holder accommodates said lens;

    wherein said attaching portion of said lens holder of said imager assembly comprises a mating surface that faces away from said lens holding portion of said lens holder;

    wherein said attaching portion comprises a plurality of pins extending from said mating surface of said attaching portion of said lens holder of said imager assembly;

    wherein said mating surface mates with said first surface of said imager circuit board when said attaching portion is attached at said imager circuit board;

    wherein, with said mating surface of said attaching portion of said lens holder mated with said first surface of said imager circuit board, individual pins of said plurality of pins are received at least partially through respective apertures of said imager circuit board;

    wherein, as received at least partially through the respective apertures of said imager circuit board, said pins locate said lens holder at said imager circuit board;

    wherein, with said pins received at least partially through the apertures of said imager circuit board, said lens is focused and optically aligned with said imager at said imager circuit board;

    wherein, with said pins received at least partially through the apertures of said imager circuit board, and with said lens focused and optically aligned with said imager at said imager circuit board, said pins are soldered at said imager circuit board so as to fixedly attach said lens holder at said imager circuit board to form said imager assembly;

    wherein said imager assembly is attached at said camera housing, and wherein circuitry of said imager circuit board is electrically connected to circuitry of said processing circuit board via a flexible electrical connector; and

    wherein, with said camera module mounted at the receiving structure at the interior surface of the vehicle windshield, said imager assembly views forward of the equipped vehicle and through the vehicle windshield.
