"Test-improve-retest", this method is to pass the preliminary developed product through the test, expose the product's weak links, analyze the product's failure mode and failure mechanism, find out the problem and immediately improve it, and then test to confirm the The problems solved have increased the reliability of the product. This method is used in the development stage of electronic products. After the system is exposed, the weak links of the product are exposed. According to the specific situation, the necessary improvements are made immediately to increase the reliability of the product. There is only one more common and serious problem, which is more targeted.
In the development stage of electronic products, after systematic testing, specific analysis should be made according to the exposed problems and flexible application. The three methods commonly used in reliability tests are often cycles, and the reliability level of one cycle is higher than that of a cycle product. In addition to passing the system test, the reliability test should also pass the climate and environmental tests, machinery Environmental testing and man-made normal use tests have exposed the weak links in product production, conducted comprehensive scientific analysis, and made corresponding improvements, so that electronic products have further improved their inherent reliability in the design and development stage.
