Abstract

The invention relates to the technical field of camera module group testing, and provides a camera module group power-on time sequence testing device and method. The device comprises a plurality of data collection interfaces, a camera module group power-on time sequence information obtaining module, a storage module, a data processing unit, and a communication module. The data processing unit enables the power-on time sequence information, obtained by the camera module group power-on time sequence information obtaining module, of a to-be-tested camera module group to be stored in the storage module, calculates the power-on time, collected by the plurality of data collection interfaces, of each power supply of the to-be-tested camera module group, and compares the power-on time with the power-on time sequence information stored in the storage module, so as to determine the accuracy of power-on time sequence of the to-be-tested camera module group. The communication module outputs the accuracy information of the power-on time sequence of the to-be-tested camera module group, thereby achieving the automatic testing of the power-on time sequence of the to-be-tested camera module group. The device is simple in operation, and is higher in testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of camera module testing, in particular to a camera module power-on sequence testing device and testing method. Background technique [0002] The camera module (CompactCameraModule, CCM) needs to test the power-on sequence in the R & D and design stage to judge whether the power-on sequence of each power supply meets the design requirements of the product. At present, an oscilloscope is generally used to complete the test of the CCM power-on sequence. The specific method is: [0003] The tester manually connects the test terminal of the oscilloscope to the test contact of the power supply of the test adapter board, and then reads the power-on delay of each power supply on the oscilloscope, and then judges based on the power-on sequence information of the camera module. Whether the power-on delay meets the power-on requirements, so as to determine whether the power-on sequence of the entire camera module mee...
