Reliability experiment is the study of failure and its impact results, to improve the reliability of the test object or to evaluate its reliability and the general term of the various tests conducted. In a broad sense, all tests conducted to understand, evaluate, assess, analyze and improve reliability can be called reliability tests. As long as there is a product, there is a reliability problem, because it runs through the whole process from product design to end of life. In this process, the product will go through the design stage, production stage and use and maintenance stage, and in each stage, there will be various reliability problems.
In the power adapter design phase, it is necessary to understand whether the designed power adapter meets the reliability index requirements of the design. In the production stage, to understand whether the power adapter has met the requirements of the design, the reliability test of the power adapter should be conducted, such as various quality control tests, etc. When the power adapter is produced, it is also necessary to implement various tests and various environmental and life evaluation tests on the finished product in order to make identification on the reliability level of the product.
In the use and maintenance phase, due to the very wide range of product use, the manufacturer of the product assessment, then only according to product specifications for some typical simulation tests to test the basic performance of the product, but it is not possible to carry out all kinds of possible environmental conditions of the test assessment. At the same time, in the field test, the product is subjected to a comprehensive stress effect, so often need to carry out field use test, in order to understand the actual level of product reliability.
Reliability tests on power adapters are conducted to achieve the following purposes.
1. In the development stage to expose the defects in all aspects of the trial product, to evaluate the reliability of the product to achieve the predetermined indicators to ensure the reliability of the shipped products.
2. To evaluate new materials, new products, new processes and new designs, and to study new test methods.
3. Production phase to provide information for monitoring the production process, exposing uncertainties that arise during use, and studying measures to prepay for failures to occur.
4. exposing and analyzing the failure patterns of products under different environmental and stress conditions and the related failure modes and failure mechanisms.
5. reliability identification or acceptance of finalized products and study of the failure distribution law of the products.
6. To improve the reliability of switching power adapter products, develop and improve the reliability test program, provide the basis for the user to select products, and provide the basis for limited reliability management.
