Test-improve-re-test", this method is to expose the weak links of the product through the test, analyze the failure mode and failure mechanism of the product, find out the problem and immediately improve, and then test to confirm the solution In the development stage of electronic products, this method has exposed the weak links of the product through system tests. According to the specific situation, immediately make necessary improvements to increase the reliability of the product. This method is more suitable for the situation where only one more common and serious problem occurs in the experiment, and it is more targeted.
In the development stage of electronic products, through systematic tests, specific analysis and flexible application should be made according to the exposed problems. The three methods commonly used in reliability testing are often repeated cycles, and the reliability level of a cycle is increased more than that of a cycle. In addition, the reliability test should not only pass the system test, but also pass the climate environment test and mechanical Environmental tests and human-made normal use tests expose the weak links of product production, conduct comprehensive scientific analysis, and make corresponding improvements to further improve the inherent reliability of electronic products in the design and development stage.
