Do you know several reliability test methods? There are many ways to test the reliability of electronic products. Here are some common methods.
* The method is the "test - problem record - retest" mode. The method is to discover the problem through the test, not to improve immediately, but to record the problem, and to focus on the failure mechanism of various failure modes before the end of a test phase and before the start of the next phase. Improvements are made and then tested. With this test method, product reliability will have a big leap forward. This kind of test method is more suitable for a batch of testing machines. There are several problems, one of which is the dominant position and the other is the secondary one.
The second method is the "test - improve - retest" mode. The method is to test the product's failure mode and failure mechanism through the test, expose the weak link of the product, find out the problem and immediately improve it, and then test and prove the problem solved, so that the reliability of the product is increased. . In the development stage of electronic products, after the system test, after exposing the weak links of the products, according to the specific situation, the necessary improvement immediately can greatly increase the reliability of the product. This method is more suitable for testing. There is only one case of more common and serious problems, which is more targeted.
The third method is the "Test with Delayed Improvement - Improvement - Retest" mode. The method combines the first method and the second method, and the problems of the product are found through experiments. Some of the improvements are in the test, and some improvements are immediately started in the test, and some are delayed until the end of the test. In the test, take immediate measures to improve the product and improve the reliability of the problem that can be improved in time. After the end of the test phase, the problem will be improved until the start of the next test, and then the test will be carried out to make the product reliable. Get a big increase. This method is more suitable for several problems in the experiment, and some problems can be easily improved in the short term, while others require a comprehensive situation that can be improved for quite some time.
