1. A vehicular camera, the vehicular camera comprising:
a lens holder accommodating a lens;
wherein the lens holder comprises a plurality of posts protruding from an attaching portion of the lens holder;
an imager printed circuit board (imager PCB), wherein the imager PCB comprises a first side and a second side opposite the first side and separated from the first side by a thickness of the imager PCB, and wherein an imager is disposed at the first side of the imager PCB, and wherein the imager PCB comprises a plurality of apertures therethrough;
wherein the attaching portion of the lens holder is positioned at the imager PCB such that said posts protrude through the apertures of the imager PCB;
wherein the posts are movable within the apertures while the lens is adjusted relative to the imager to align the lens relative to the imager; and
wherein, with the lens aligned relative to the imager, the posts are heated to deform within the apertures, whereby the deformed posts harden upon cooling to secure the lens holder relative to the imager PCB.
