What is the reliability of electronic components

Why do a batch of electronic components have passed the basic performance test, and some of them will break down after a period of time?

Why do electronic components of the same model and specification with higher basic performance value sometimes have more bad products?

That's because the basic performance does not reflect all the quality. There is an inherent attribute of electronic components - reliability!

Reliability is the ability of a product to work continuously and stably. The basic performance of electronic components directly indicates whether the static quality is qualified or not, which can not reflect the overall picture and stability of product quality.

The basic performance index of electronic components is high, and its reliability is not necessarily high. If the reliability of the product is low, no matter how good its initial technical performance is, it will not be brought into play. For example, the products with higher dielectric breakdown voltage of ceramic chip capacitor are likely to have higher failure rate in high temperature load accelerated life test.

Reliability can comprehensively reflect the quality of products. The reliability of electronic components is the basis of the reliability of electronic equipment. In order to improve the reliability of equipment or system, the reliability of electronic components must be improved. Reliability is an important quality index of electronic components, which must be examined and tested.

The scope of "electronic components" mentioned here is relatively large. For example, Fenghua chip resistor, chip capacitor, chip diodes and triodes all belong to electronic components. Therefore, we can focus on the reliability of various electronic components when selecting electronic components.
