Generally speaking, the test conducted to evaluate and analyze the reliability of electronic products is called reliability test. Through reliability test, the reliability characteristic quantity of electronic products when working or storing under various environmental conditions can be determined, so as to provide useful data for use, production and design; It can also expose the problems existing in the design, raw materials and process flow of the product.

For products, the higher the reliability, the better. Products with high reliability can maintain long-term normal operation; In professional terms, the higher the reliability of the product, the longer the time the product can work without failure. Chuangxin testing, established in 2018, has always adhered to the purpose of "professionalism, authority, efficiency and innovation". It has purchased international advanced testing equipment with a large amount of money. The testing is in strict accordance with international testing standards and methods. It has obtained CNAs certification and international mutual recognition qualification. Its customer base covers many countries and regions at home and abroad. It is a professional IC testing institution with excellent quality and high popularity in China.

Reliability test items, generally speaking, the test conducted to evaluate and analyze the reliability of electronic products is called reliability test. Through reliability test, the reliability characteristic quantity of electronic products when working or storing under various environmental conditions can be determined, so as to provide useful data for use, production and design.

The purpose of electronic product reliability test usually includes the following aspects:

1. In the development stage, it is used to expose the defects of trial products in all aspects and evaluate whether the product reliability reaches the predetermined index;

2. Provide information for monitoring the production process in the production stage;

3. Carry out reliability appraisal or acceptance of finalized products;

4. Expose and analyze the failure rules, relevant failure modes and failure mechanisms of products under different environments and stress conditions;

5. In order to improve product reliability, formulate and improve reliability test scheme, and provide basis for users to select products.

Commonly used reliability tests can be divided into five categories:

A. Environmental test B. life test C. screening test D. field service test E. qualification test
