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.
Claims19
A camera module for a portable electronic device, comprising:
- a barrel;
- a first lens adhered in the barrel by an ultraviolet (UV) adhesive, the UV adhesive cured between 75° Celsius and 100° Celsius for 20 to 30 minutes whereby the UV adhesive is volatilized little;
- a holder retaining part of the barrel;
- and
- an image sensor below the first lens, the image sensor being packaged with a Ceramic Leaded Chip Carrier.
An image pick-up module for a portable electronic device, comprising:
- a lens receiver used to receive at least one lens therein and allow incident light to pass through said at least one lens;
- an adhesive for attaching said at least one lens to said lens receiver and having said at least one lens fixed therein, said adhesive applied to a periphery of said at least one lens with a significantly small area, and having a property of slow volatilization;
- and
- an image sensor spaced from said lens receiver for accepting illumination of said incident light passing through said at least one lens and generating image signals corresponding to said incident light.
A method for installing an image pick-up module of a portable electronic device and enhancing performance thereof, comprising the steps of:
- providing a lens receiver having a path therein for incident light to pass along;
- fixing at least one lens interferingly in said path and to said lens receiver with a slowly volatilizing adhesive by applying a predetermined treatment on said adhesive;
- and
- installing an image sensor spaced from said lens receiver for accepting illumination of said incident light and generating image signals corresponding to said incident light.
