ABSTRACT:
A digital camera module (10) for a portable electronic device includes a barrel (12) containing a first lens (122) and a second lens (124), a holder (15) containing part of the barrel, and an image sensor (141) below the first and second lenses. The first and second lenses are adhered in the barrel by an ultraviolet (UV) adhesive. The UV adhesive is cured between 75° Celsius and 100° Celsius for 20 to 30 minutes, and is volatilized little. The image sensor is packaged with a Ceramic Leaded Chip Carrier. The structure of the digital camera module can effectively protect the first and second lenses thereof from moisture, dampness, and oxidation.
