The importance of aging testing on the quality of electronic products

The aging test refers to the process of simulating the product under the conditions of the actual use conditions to carry out the corresponding conditions to strengthen the experiment.

At present, high-temperature aging process is widely used at home and abroad to improve the stability and reliability of electronic products. Through high-temperature aging, the hidden dangers in the production process of defects, welding and assembly of components can be exposed in advance, and the products that pass the factory can be guaranteed.

With the development of electronic technology, the degree of integration of electronic products is getting higher and higher, the structure is more and more subtle, the process is more and more, and the manufacturing process is more and more complicated, so that latent defects are generated in the manufacturing process. A good electronic product requires not only high performance but also high stability. The stability of electronic products depends on the rationality of the design, the performance of the components and the manufacturing process of the whole machine. Product quality theory tells us that most of the product failures occur at the beginning and end.

The end of the period is the normal life of the product, which cannot be controlled. But the initial stage is controllable and can be controlled within the factory gate. That is to do the aging test before handing the product to the user, killing the problem inside the factory. The formal manufacturer is doing this, but the cottage factory generally does not do the aging test, or the work of aging test is given to the user. Since the user has claimed part of the work of the cottage factory, the cottage products are generally much cheaper. Of course, a good-shoulder user sometimes buys a cottage product that can be used for a long time. The product quality theory says: "If a product can work continuously for one day without failure, then it is likely to be able to work continuously for one year without failure," so if you buy a product for a few days without any damage, Then it may follow you for many years, in fact, this is the result of the aging test passed. If the purchased product does not take long to break or the product defect rate is too high, and various minor problems are likely to occur, it is obvious that the product has not undergone a strict aging test process.

It is unrealistic to test each component for thousands of hours, so it is necessary to apply thermal stress and bias to accelerate the early exposure of such defects, and to make the product enter the stable period as soon as possible through the initial stage of the failure bath feature.

The aging test of product quality is indispensable, and the aging test room of Huanrui test can be customized according to customer needs.
