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.
