Conduct Types of Reliability Appraisal Of Finalized Products Or Acceptance
In Order To Improve Product Reliability, Formulate And Improve Reliability Test Plans
During the development stage, our reliability tests are used to expose and analyze the failure laws and related failure modes and failure mechanisms of products under different environmental and stress conditions.
Reliability testing refers to testing and verifying the reliability of products. The research finds out the weak points of the product with limited samples, time, and usage costs.
Reliability test is a general term for various tests conducted to understand, evaluate, analyze and improve the reliability of products. Reliability testing is an effective method to eliminate early product defects, increase or test product reliability levels, test product reliability indicators, and evaluate product life indicators by imposing typical environmental stresses and working loads. According to the needs to be achieved, different types of reliability tests can be carried out during the design, development, production and use stages of the product.

Reliability refers to the ability to complete the specified function in the specified time and under specified conditions. Mainly have the following 3 aspects
(1) Find various defects in the product design, components, parts, raw materials and craftsmanship.
(2) Confirm whether it meets the reliability quantitative requirements or evaluate the reliability level of the product.
(3) Obtain various other useful information.
Mechanical environment: improve the strength of the product structure, select higher standard devices, or protect the device structure through external means.
Electrical stress: reduce the electronic stress of its own equipment and reduce the external interference electronic stress
1. Identify and improve life bottlenecks
2. Improve stress standards
3. Improve the use environment
4. Effective isolation: electrical isolation, functional isolation, spacing isolation or shielding.
5. Reduce the effect of failure
6. Appropriate over-design of passive devices
7. Design a replaceable protection module
The measurement indicators of product reliability include reliability, failure degree, failure probability density, failure rate, average life and reliable life, and average trouble-free working time.
