Highly Accelerated Stress Screening For Air-cooled Switching Power Supplies
Highly Accelerated Stress Screening, or HASS, has been established as a best practice for
assuring fielded electronic product reliability. HASS is especially productive in power
conversion equipment, where component stress levels are typically more aggressive than
found in other products. TDI has been instrumental in establishing HASS as a viable, high
value-add production process.
This White Paper is the first in a series of documents outlining this process. Background
information is provided regarding electronic equipment failure mechanisms and the
predictive models that can be used to describe them.
