SDTA - Stress Derating and Thermal Analysis from BQR |
Stress de-rating and Thermal Analysis
| Reliability is a major factor in product design. For this reason there is an increasing need for proper component selection to match end customer operating environments. Components tend to fail when operating near their rated stress values and therefore, operation at derated conditions is mandatory.
SDTA compares the actual operating stress of each component with the allowed component stress within its operating environment. It assists the designer to evaluate the best derating decisions - either to reduce the stress of the part or increase the stress rating of the component. It examines all types of stress characteristics such as power, voltage, current and temperature.
Key Benefits of the SDTA
- Optimizes the component size and cost vs. reliability
- Increases reliability performance
- Identifies components over specified de-rating limits
- Identifies design improvements for electrical parameters

 |
- Compares the operating values and the allowed de-rated values
- Recommends to replace over-stressed components - improves reliability
- Recommends to replace under-stressed components - reduce PCB area, thus reducing costs
- Ready de-rating curves according to Military and Industrial criteria
- Ready de-rating curves according to NAVSEA TE000-AB-GTP-010 Revision 2
- User defined De-rating Curve
