Type_C earphone PCBA and electrical parameter test system and test method thereof

Abstract

The invention provides a Type C earphone PCBA and electrical parameter test system and a test method thereof. The method comprises the following steps: S1, waiting for clamping; S2, judging whether toaccess or not: after an operator clamps one tested PCBA on one test fixture, enumerating the PCBA by an operating system, finding the tested PCBA by test software according to PID and VID of the PCBA, and for a scene in which a plurality of PCBAs of the same model are inserted, sending a detection signal to the equipment for further verification after the tester detects the conforming equipment,if the test software detects that the PCBA meeting the test condition is accessed, entering the step S3, otherwise, returning to the step S1; S3, reading information: reading the information of the tested PCBA; S4, automatic testing: testing the PCBA to be tested by the testing software; and S5, test result processing: completing test processing of the tested PCBA by the test software, displayinga test statistical result through a display, and cooperating with an MES system for unified management. The system can achieve the automatic testing of the electrical performance of the PCBA of the Type_C earphone, is complete in function, and is convenient to use.

Description

【Technical field】 [0001] The invention relates to the technical field of test and measurement, in particular to a Type-C earphone PCBA and an electrical parameter test system and a test method thereof. 【Background technique】 [0002] Most of the existing test schemes adopt the method of putting the PCBA under test and starting the test under the control of the operator. At the same time, serial operation is mostly used, and only one PCBA is allowed to be connected to the host. The test results are stored locally, and later collected and sorted by specialized personnel at each workstation. [0003] The above testing scheme has the following defects: [0004] 1. After accessing the tested product, it is impossible to automatically judge whether the tested product is connected effectively, and the operator needs to click to start the test and then observe the results, which is not convenient enough to operate; [0005] 2. One host can only test one PCBA at a time, and the op...

AI Technical Summary

Problems solved by technology

[0004] 1. After accessing the tested product, it is impossible to automatically judge whether the tested product is connected effectively, and the operator needs to click to start the test and then observe the results, which is not convenient enough to operate;

[0005] 2. One host can only test one PCBA at a time, the operator needs to alternately perform clamping operations and wait for the test to be completed, and the test efficiency is low

[0006] 3. Using VID and PID to identify the tested PCBA, it cannot be effectively distinguished when multiple headphones are connected

[0007] 4. The test results are not convenient for unified management

[0008] 5. Single test function, not convenient enough to use
