Problems solved by technology

As a result, the heat generated by the electronic components on the circuit board cannot be transmitted to the outside in time, which will cause the circuit board and photosensitive chip to expand due to heat, and even bend and deform
The inner lens of the lens may also be deformed or shifted due to heat
After the incident light enters the camera, the optical path deviates from the design value, which affects the image quality

Abstract

A camera module, the camera module includes: a circuit board; a photosensitive chip, the photosensitive chip is fixed on the circuit board and electrically connected with the circuit board; and a supporting base, the supporting base is fixed on the circuit board Above, the support base includes a first storage tank, the photosensitive chip is accommodated in the first storage tank; at least one air escape hole is opened on the support base, and a heat conduction member is accommodated in the escape hole, and the heat conduction member passes through a However, a thermally-capable glue is fixed in this vent hole. The camera module provided by the invention not only has a good heat dissipation effect, but also can enhance its stability.

Description

technical field [0001] The invention relates to the field of electronic and optical devices, in particular to a camera module. Background technique [0002] Most mobile phone camera modules currently on the market are composed of six major parts: lens, motor, filter, photosensitive chip, plastic base, and circuit board. [0003] In order to prevent dust from entering the module and affecting the image quality, the plastic base, lens and circuit board form a completely enclosed space. As a result, the heat generated by the electronic components on the circuit board cannot be transmitted to the outside in time, which in turn causes the circuit board and the photosensitive chip to expand due to heat, or even bend and deform. The lens inside the lens may also be deformed or shifted due to heat. After the incident light enters the camera, the optical path deviates from the design value, which affects the image quality. Especially when taking pictures continuously, the longer t...
