Relibility Testing Paradigm Shift:

Traditional Approach

  • Test to design limits
  • If it meets specifications its "good enough!"
  • combined environments rarely applied
  • testing requirements defined by the customer

Paradigm Shift

  • Engineers trained to mathematically model - Much more intellectual satisfaction - confidence in prediction.
  • Mathematical models are good for design of electgronics and mechanical or chemical wear out processes.
    • Limited for predicting most electronic failures
    • Most electronic failures are by defect in design or manufactur, not wearout.
  • Experimental Approach more "brute force"
    • intellectual satisfaction is found in the investigation of root cause - component and physics of failure.
