Abstract
A vehicular camera includes a lens accommodated in a lens barrel, a lens holder that accommodates at least part of the lens holder, and a printed circuit board with an imager disposed thereat. After the lens is optically aligned with the imager, the adhesive is initially curable to an initially-cured state in an initial curing process for an initial-cure time period. The initially-cured adhesive is further curable to a further-cured state in a secondary curing process for a further-cure time period that is longer than the initial-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the vehicular camera in a vehicle. The further-cured adhesive maintains at least 70% strength of bond after being exposed for 1000 hours to a temperature of 85 degrees Celsius and a humidity of 85% RH.
