Embodiment Construction
[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0034] The camera module airtight detection method of the present invention is used to detect the camera module airtightness, and the camera module airtight detection method can detect figure 1 The tightness of the camera module shown in . Please refer to figure 1 , the camera module includes a circuit board 10 , an imaging chip 20 , a support base 30 , a filter 40 and a lens assembly 50 . The imaging chip 20 and the support base 30 are both arranged on the circuit board 10, and the imaging chip 20 is located in the space surrounded by the support base 30 and the circuit board 10, the optical filter 40 and the lens assembly 50 are installed on the support base 30, and T...

The invention provides a camera module tightness detection method. The camera module tightness detection method comprises the following steps: performing a water vapor leakage experiment on a camera module to be detected; performing fluorescent treatment on the camera module to be detected undergoing the water vapor leakage experiment; observing the surface of the camera module to be detected under the irradiation of ultraviolet light, and judging the position of water vapor leakage according to the existence of a light emitting point on the surface of the camera module to be detected; and acquiring the section of the camera module to be detected, observing the section of the camera module to be detected under the irradiation of the ultraviolet light, and judging the position of the watervapor leakage according to the existence of a light-emitting point on the section of the camera module to be detected. According to the camera module tightness detection method provided by the invention, the camera module is subjected to fluorescent treatment, the water vapor leakage position of the camera module is judged rapidly by observing whether the light-emitting point exists on the cameramodule or not, and the poor tightness position of the camera module can be found. The camera module tightness detection method has the advantages of convenience, rapidness and accuracy.
Description
technical field [0001] The invention relates to the field of imaging technology, in particular to a method for detecting the airtightness of a camera module. Background technique [0002] With the development of technology, various electronic devices such as computers and mobile phones are generally equipped with camera modules to take pictures anytime and anywhere, which greatly facilitates consumers and enriches people's lives. Therefore, the demand for camera modules is increasing. [0003] After the camera module is manufactured, its quality usually needs to be checked, such as the sealing of the camera module. Usually, the area above the optical filter of the camera module is not sealed, but the area from the optical filter to the imaging chip needs to be completely sealed. Some camera modules found in the test that after a temperature of 85 degrees and a humidity of 85 degrees, water vapor appeared in the area to be sealed, and it disappeared after 48 hours, which sh...
