Abstract

The invention relates to a camera module, a dust prevention and fixing method and an installation method of the camera module, wherein the camera module comprises a circuit board, a plurality of passive elements and adhesive layers, wherein the passive elements are fixedly arranged on the circuit board; the adhesive layers cover the surfaces of the passive elements; the adhesive layers are filled in gaps among the passive elements. The dust prevention and fixing method comprises the following steps: dispensing adhesive on the surfaces of the passive elements of the camera module to form the adhesive layers; filling the gaps among the passive elements with the adhesive layers. The installation method of the camera module comprises the following steps: after applying gold threads, before mounting a bracket, dispensing adhesive on a circuit board area attached below the bracket and the surfaces of the passive elements of the camera module to form the adhesive layers; filling the gaps among the passive elements with the adhesive layers. The camera module, the dust prevention and fixing method and the installation method of the camera module can solve the problem that foreign matters are easily hidden among passive elements and easily fall down during vibration.

Description

technical field

[0001] The invention relates to the technical field of image communication, in particular to a camera module, a dustproof firmware method for the camera module, and a method for installing the camera module. Background technique

[0002] General camera modules for mobile phones, tablet computers, etc., are composed of components such as lenses, voice coil motors, filters, sensors, passive components, and circuit boards. Most of the passive components are placed on the circuit board, and there are gaps between the passive components, which are easy to hide foreign objects such as dust and tin slag, which will cause hidden dangers of bad images on the module. Moreover, during the vibration process, there is a risk of the passive components falling off. Contents of the invention

[0003] Based on this, it is necessary to provide a camera module for the problems that foreign matter is easy to be hidden between passive components and easy to fall off during vib...
