The test conducted to evaluate and analyze the reliability of electronic products is called reliability test. It simulates the environmental accelerated test according to the factors such as different use environments and stress of different environments that the products may encounter in the use process, so as to evaluate the performance and adaptability of products or sample materials, and provide quantitative technical indicators of environmental adaptability of products or sample materials for scientific researchers and product development engineers.

Product reliability test refers to an accelerated test method for product or sample material to achieve the specified functional characteristics within the specified time under the conditions of simulating a natural environment. Products with high reliability can not only save costs for enterprises and win the trust of customers, but also help to improve the brand awareness of enterprises and enhance the market competitiveness of products.Therefore, all countries have formulated corresponding standards in product reliability testing.Reliability testing involves product R & D, design, production, transportation and other stages,

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

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

3. 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.

What should the reliability test of electronic product testing organization test?

1. Climatic environment test:High temperature test, low temperature test, temperature and Humidity Cycle / constant damp heat test, cold and heat shock test, rapid temperature change test, low air pressure test, light aging test, corrosion test, etc

9. Failure analysis test:Micro measurement and analysis of surface / polar surface, non-destructive measurement and analysis, electrical performance measurement and analysis, physical performance measurement and analysis, welding process measurement and analysis, PCB / PCBA measurement and analysis, electronic components measurement and analysis, plastic / rubber / polymer material flow and analysis, metal material measurement and analysis.

Product reliability test can be divided into mechanical environment test and climatic environment test according to the main factors damaged by its use environment. Its working principle is to comprehensively analyze the performance of products or sample materials through a series of test items according to a series of factors such as climatic conditions, environmental conditions and load level that products may encounter under certain environmental conditions, find out the causes of faults, and take elimination and preventive measures, Ensure the quality of products or sample materials in terms of quantification, and ensure the safety and durability of products or sample materials. For different products, in order to achieve different purposes, different reliability test methods can be selected.
