DELL PG Component Derating! 供大家参考！！
2. Introduction
2.1 Purpose
The purpose of component derating is to improve a product’s inherent design reliability, increase its operating margins, and ultimately reduce warranty costs. The goal is to achieve a more robust design.
Through derating the design is enhanced by compensating for many variables inherent in any design. The benefits of proper component derating include lower failure rates through reduced stresses, less impact from material and manufacturing variability, and proper circuit operation with part parameter changes.
2.2 Scope
The intent of this document is to provide the engineering community a guideline that will be used to design-in reliability and product robustness. The information contained within this document is applicable to all equipment marketed by Dell worldwide; both internally designed and procured from external sources. |
