Subject: MIL-HDBK-217 Prediction Models
Message:
The front section 4 of MIL-HDBK-217 identifies the limitations of the reliability prediction models: "... none of the models in this handbook predict nuclear survivability or the effects of ionizing radiation." I am interested in any information pertaining to prediction models for resistors, capacitors, and diodes that are used in an ionized gas environment created by nucleating particles.

Subject: Survey of companies doing TAAF
Message:
Criscimagna and Zsak wrote an article "Reliability Growth" in the "Jour of RAC" (3rd Quarter 1998). It is similar to the use of the Test-Analysis-And-Fix (TAAF)approach (http://www.bmpcoe.org/how-to/books/taaf/intro.html) to increase the reliability of products. This approach was adopted by Army, Navy, and Air Force.
Do you know any companies implementing this approach? Any companies use it for non-military, commercial products?

Subject: Burn-in
Message:
Does burn in today buy you anything? We currently perform a static burn in with after burn test defects around 0.001%.
Dynamic burn in has been suggested. What about HALT testing on prototypes and eliminating burn in on production lots. Any input would be much appreciated. Thanks, Mark

Subject: Nonelectronic Failure Rates
Message:
I'm looking for a very good source to obtain nonelectronic failure rates.
 
Is there any relsoftware that computes nonelectronic failure rates?
