Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem existing in the prior art that when the PCBA in the mass production process of the Android device fails to be detected, it needs to be disassembled, repaired and then reassembled for secondary detection, and the production efficiency is greatly reduced; High; the unassembled PCBA is not connected to the LED display unit, and it is not convenient to use APP and other automated function testing software for testing. A software implementation method for testing PCBA in the mass production process of Android devices is provided.

Embodiment 1

[0029] like figure 1 and figure 2 Shown, a kind of software implementation method of testing PCBA in the mass production process based on Android equipment, is characterized in that, comprises the following steps:

[0030] S1: Compile the program that can run the PCBA function test in recovery mode;

[0031] Compile the PCBA function test tool into a binary executable program that can run on the target Android device, and package it into the sbin directory of the recovery root file system

[0032] S2: Modify the default startup mode of the Android system, start the PCBA in the mass production process of the Android device, and realize the automatic calling of the PCBA function test program in the recovery mode;

[0033] Said S2 comprises the following steps:

[0034] S21: Bootloader reads the recovery field of the Bootloader_message structure written in advance by the MISC partition, modifies the value of command[32] to boot_recovery, and starts the recovery mode;

[0035...

Embodiment 2

[0049] like figure 2 As shown, first execute the PCBA test program; when the test starts, the green LED on the PCBA is always on; if the test function module A passes the test, go to the next step, if the test fails, the test ends, and the red LED on the PCBA is always on. PCBA test failed; test functional module B, pass the test, go to the next step, if the test fails, the test ends, the LED on the PCBA is always red, and the PCBA test fails; follow the above steps to test the last functional module on the PCBA, If the test is passed and the test is over, the green LED light flashes, and the PCBA test is passed; otherwise, the test is over, the red LED light is on, and the PCBA test fails.

[0050] By adopting the above technical solution, it is possible to quickly and reliably identify the quality of PCBA functional modules during the functional testing process of Android devices, avoiding unnecessary installation processes of non-compliant PCBA, and improving production ef...

Abstract

The invention discloses a software implementation method for testing PCBA in the mass production process of an Android device, and belongs to the technical field of software automation testing. The backup function recovery of Android devices is adopted, and the test results are identified by the different states of the LEDs on the PCBA, so that the quality of PCBA functional modules can be quickly and reliably identified during the functional test of Android devices, avoiding non-compliance The unnecessary installation process of PCBA improves the production efficiency and solves the problem of low production efficiency in the existing technology, high error rate of manual programming and directory detection, unassembled PCBA is not connected to the LED display unit, and it is not convenient to use automated function tests such as APP Software testing issues.

Description

technical field [0001] The invention relates to the technical field of software automation testing, in particular to a software implementation method for testing PCBA in the mass production process of Andriod-based equipment. Background technique [0002] At present, most of the testing methods used in the mass production of Android devices are functional testing APPs. At this stage, Android devices have been assembled into complete devices. The complete devices that fail to be inspected need to be disassembled for maintenance and reassembled for secondary testing, which greatly reduces the cost of testing and testing. Productivity. Screening PCBA for defects before assembling the whole machine can greatly improve the test pass rate of the whole machine. The functional inspection of PCBA in the existing production process is mostly manual burning and visual inspection, which has a very high probability of error. Since the unassembled PCBA is not connected to the LED displa...
