Electronic component testing is the application of testing service industry technology in electronic information industry. It is an important link in the specific industrial chain of electronic components. The level of testing service technology is closely related to the quality of electronic components. Electronic technology is an emerging technology developed at the end of the 19th century and the beginning of the 20th century. It has developed most rapidly and widely used in the 20th century, and has become an important symbol of the development of modern science and technology. How to accurately and effectively detect the relevant parameters of components and identify the quality of components must adopt different methods according to different components, so as to judge whether the components can work normally.

(1) Electronic component testing is an effective guarantee for product quality and reliability

Electronic component testing is an effective guarantee for product quality and reliability. Testing usually includes testing and screening test. A large number of applications and tests show that the failure time curve of electronic products is characterized by high at both ends and low in the middle, in a bathtub shape, which is usually called "bathtub curve".

Bathtub curve

"Bathtub curve" is the curve that the failure rate of components changes with time. The early failure rate decreases rapidly with the increase of time, and the failure rate remains basically unchanged during the service life (or accidental failure period). In the loss failure area, the product failure rate increases with time, such as mechanical parts damage, function degradation, parameter drift and so on. The process of test and screening test is to promote the components to enter the service life period in which the failure rate remains constant in advance, and eliminate the failed components during this period.

The test to evaluate and analyze the reliability of electronic products is called reliability test. With the increasing quality requirements of electronic products in industrial, military and civil departments, the reliability of electronic equipment has attracted more and more attention. Testing and screening of electronic components is one of the most effective measures to improve the reliability of electronic equipment. The purpose of reliability test and screening is to select highly reliable components from a batch of components and eliminate products with potential defects.

(2) Electronic component testing provides quality assurance for the development of downstream application industry

Testing service is an important link in the electronic information industry chain. Taking the integrated circuit industry as an example, its industry chain can be divided into integrated circuit design, chip manufacturing, packaging and testing. Integrated circuit finished product testing and wafer testing are important links in the industry chain. The professional division of labor has made some independent integrated circuit testing service providers in the market.

The reliability of electronic components is the basis of the reliability of electronic equipment. With the development of the times, the electronic industry has made great progress under the promotion of science and technology. The specific performance is that the application of electronic products has penetrated into all aspects of production and life. As an important part of electronic products, the stability and quality reliability of electronic components have become the key to the normal work of electronic products. Therefore, the electronic component testing industry has sprung up, which has become an indispensable and important link in the field of related electronic industry.

Electronic component testing effectively controls the performance parameters of electronic components through effective quality control and scientific screening, so as to give full play to its role, so as to ensure the product quality of electronic equipment and finally improve the stability and reliability of the whole electronic product. With the expansion of the scope of use of electronic components, the testing of electronic components has also penetrated into various fields of China's production, including aerospace and electronic national defense. The testing of electronic components provides technical support for China's high-end science and technology.
