Method, device and system for testing circuit board card

Abstract

The invention discloses a method, device and system for testing a circuit board card. A board card identification of the circuit board card can be obtained, and test record files of bad board cards are looked for according to the board card identification, so that whether the circuit board card has already been tested and whether a test fault occurs are determined; if the circuit board card has already been tested and the test fault occurs, a fault function point of the last test is determined when a current test script is determined to be the same as a test script used in the last test, and a test instruction can be obtained from the current test script according to the fault function point so that the circuit board card can be tested; otherwise, if the current test script is determined to different from the test script used in the last test, the whole circuit board card is tested again, namely test instructions are obtained sequentially from the current test script so as to test the circuit board card. According to the method, device and system for testing the circuit board card, the circuit board card can be tested more flexibly, and test efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method, device and system for testing circuit boards. Background technique [0002] With the rapid development of communication technology, the types and demands of electronic products are also increasing day by day. As the core part of electronic products, how to improve the production efficiency of circuit boards has become a problem that manufacturers are extremely concerned about. [0003] In order to ensure the product quality of circuit boards, such as TV (TV) boards or mobile phone boards, performance tests are required before they leave the factory. In the prior art, performance tests are usually performed manually . When performing performance tests on circuit boards, it often occurs that a certain circuit board cannot be tested when a certain function is tested (that is, a test error). Generally, this phenomenon is called "again (NG, Next). Generation)". Among ...

AI Technical Summary

Problems solved by technology

Among them, there are many reasons for this NG, for example, it may be a product quality problem, or a test tool or wire problem, etc., but no matter what the reason is, it is necessary to check the circuit again after finding out the reason. The board is tested, or the circuit board is repeatedly tested, which greatly affects the efficiency of the test. For this reason, the prior art has proposed a scheme for automatically testing the circuit board. In this existing program, generally A test script will be specially set up for the test task. When the circuit board needs to be tested again or repeatedly tested, use the computer to run the test script to retest all the functions of the circuit board.

[0004] In the process of research and practice of the prior art, the inventor of the present invention found that although the existing test scheme can improve the test efficiency to a certain extent, due to the NG, all the circuit boards need to be tested again , so it is not flexible enough and the test efficiency is not high
