Abstract
A method of assembling a vehicular camera includes providing (i) a lens accommodated in a lens barrel, (ii) a camera front housing, (iii) a printed circuit board with an imager. An uncured adhesive is dispensed (i) between the lens barrel and the front portion of the camera front housing or (ii) between the printed circuit board and the rear portion of the camera front housing. The lens is brought into focus with the imager, and the adhesive is initially cured in an initial radiation curing process. After the initial radiation curing process, the initially-cured adhesive is further cured in a secondary curing process. The further-cured adhesive limits movement of the lens relative to the imager to less than +/−18 microns after (i) exposure to 90 degrees C. for 400 hours and (ii) exposure to 85 degrees C. at 90% relative humidity for 240 hours.
