1. Use high environmental stress to stimulate product design defects in advance, thereby eliminating design defects and greatly improving design reliability;
2. Maintenance costs are greatly reduced, because the delivered products have higher reliability;
3. Understand the design capabilities and failure modes of the product;
4. Highly accelerated life test can find out the working limit and failure limit of the product, and provide a basis for formulating HASS (Highly Accelerated Stress Screening) plan and determining the strength level of HASS;
5. The failures during the qualification test are greatly reduced. The qualification test is not important for the products that have passed the high-accelerated life test, it is only a form.
