Electronic products may face various environments and stresses during use, such as high temperature, low temperature, humidity, vibration, electromagnetic interference, etc. These factors may have a negative impact on the performance and reliability of the product, leading to product failure. To help everyone gain a deeper understanding, the following content is organized by Chuangxin Testing Network and provided for your reference.

The failure of electronic products can usually be divided into the following stages:

1. Initial failure stage: Initial failure is usually caused by defects or material quality issues during the manufacturing process. For example, poor contact of solder joints, excessive grain size, and insufficient material purity can all lead to initial failure. Initial failure usually occurs in the early stages of product use, which has a significant impact on the reliability and performance of the product.

2. Normal service life failure stage: Normal service life failure is usually caused by factors such as environment and stress. For example, changes in temperature, humidity, vibration, electromagnetic interference, etc. can all lead to failure during normal use. Failure during normal use usually occurs gradually with the increase of product usage time, which has a significant impact on the reliability and performance of the product.

3. Accelerated failure stage: Accelerated failure is usually caused by factors such as environment and stress that accelerate the aging or damage of the product. For example, using the product under conditions such as high temperature, high humidity, and high voltage may lead to accelerated failure. Accelerated failure usually occurs in a short period of time and has a significant impact on the reliability and performance of the product.

4. Sudden failure stage: Sudden failure is usually caused by stress exceeding the product's tolerance or other unpredictable factors. For example, the product may experience sudden failure due to impact, vibration, electric shock, etc. during use. Sudden failure usually has a serious impact on the reliability and performance of products, and can even lead to product damage or danger.

In order to reduce the failure of electronic products, comprehensive considerations and measures need to be taken in product design, manufacturing, testing, and maintenance. For example, in the product design stage, the reliability and stability of the product should be considered, high-quality materials and components should be selected, and strict testing and verification should be conducted; During the manufacturing process, the stability and controllability of the production process should be ensured to ensure the quality and performance of the product; During the testing and maintenance phase, comprehensive testing and maintenance should be carried out to promptly identify and resolve product issues. Through these measures, the reliability and stability of electronic products can be improved, and the risk of product failure can be reduced.
