specific Embodiment approach

[0065] The present invention adopts first kind of method to carry out the specific implementation mode of single board function test as follows:

[0066] 101. Fix the mobile phone single board on the fixture;

[0067] 102. Use the test pen to press the power button on the keyboard to start the machine;

[0068] 103. Check the LCD display on the fixture, and verify whether the display function of the mobile phone single board is normal. If the LCD display is normal, continue to the next test step; if the LCD display shows abnormal phenomena such as flickering and stripes, then end this test.

[0069] 104. Input instructions on the keyboard, start the function test software, and start the function test;

[0070] 105. The function test software displays the software version number through the LCD on the test fixture to check whether the software version is correct;

[0071] 106. By testing the pronunciation of the speaker on the fixture, check whether the function of the speak...

Abstract

The invention discloses a system and a method for the functional test of a mobile phone single board. Aiming to solve the problems of high cost but low efficiency of functional test technology of the existing mobile phone single board, the mobile phone single board test system of the invention comprises a test fixture, functional components, a power supply, a synthetic tester and a computer. The mobile phone single board is fixed on the test fixture, and the mobile single board test point contacts the test probe of the test fixture. The power supply provides power for the mobile phone single board. The functional components fixed on the test fixture are used for the functional test to the mobile single board. The computer controls the synthetic tester to calibrate and test the radio frequency of the mobile phone single board by the test fixture. The test method comprises the followings steps. Firstly, the mobile phone single board is fixed on the test fixture. Secondly, the mobile phone single board is started. Thirdly, a LCD displays images. If the display is normal, the fourth step can be carryout out; otherwise the test ends. Fourthly, the mobile phone single board is tested. The invention has the advantages of low cost as well as high efficiency.

Description

technical field [0001] The invention relates to a system and method for functional testing of a single board of a mobile phone. Background technique [0002] The mobile phone single board refers to the mobile phone PCB board that has been SMT mounted. Various chips and components have been soldered on the PCB board, but the liquid crystal display (LCD), speaker, motor, and microphone (Mic) are not installed. , Receiver, camera and other functional components. [0003] Because the development cycle of mobile phones is short and the production schedule is tight, the test system and method for mobile phones are required to develop test equipment with a short development cycle and low cost, and at the same time, the test equipment can effectively detect and locate mobile phones faults and reduce bad costs. During the production process of mobile phones, manufacturers will test the mobile phones to ensure the quality of the mobile phones. Generally, two methods are used for de...
