Camera module radio frequency interference test system

Abstract

The embodiment of the invention provides a camera module radio frequency interference test system. The camera module radio frequency interference test system comprises a lighting device, a probe and aspectrum analysis device, the probe is connected with the spectral analysis device, and the probe is movably arranged close to the lighting device; the lightening device is used for installing a camera module to be tested and driving the camera module according to a preset lightening condition; the probe is used for collecting a radiation signal of the camera module; and the spectrum analysis device is used for analyzing the radiation signals. The camera module radio frequency interference test system can effectively and accurately test the radio frequency interference of the camera module monomer.

Description

technical field [0001] The invention relates to the technical field of camera module testing, in particular to a camera module radio frequency interference testing system. Background technique [0002] When the camera module is working, the main clock and the internal system clock will emit high and low frequency electromagnetic waves. When the frequency of the signal received by the mobile phone antenna is very close to the electromagnetic wave frequency, the electromagnetic wave generated by the camera module will interfere with the communication. Therefore, mobile phone production needs to meet the corresponding radio frequency interference standards to minimize such interference. At present, in the industry, after the camera module is assembled into the mobile phone, the communication interference test is carried out on the whole machine. If the radiation interference of the camera module cannot be resolved, and a small batch of production has been carried out in the e...

AI Technical Summary

Problems solved by technology

If the radiation interference of the camera module cannot be resolved, and small batch production has been carried out in the early stage, further modification at this time will cause large economic losses and lead to an extension of the development cycle

[0003] Therefore, how to better test the radio frequency interference of the camera module at present, so as to avoid causing a lot of economic losses and prolonging the development cycle has become an urgent problem to be solved.
