Reference conditions for failure rates and stress models for conversion. Most of the resources for reliability development of electronics should be on finding causes of unreliability based on real data from the field. What are you 617709 asked to forecast?

While not a full textbook, it make a major step forward. The standard still uses failure rates and modifications as the structure. Compounding the challenge of prediction is that it requires many broad assumptions about average end use stress environment, use profile, and capability and consistency of the iex processes at many levels of assembly.

Because of the lack of distributed knowledge on causes of real warranty failures the belief and decades long delusion that the rates of failures of electronics with no moving parts can be predicted. Often we do not have time for this approach. The only way this could be shown to be true is by having many electronic companies disclose the actual causes of most of their failures in the early years of use.

There may be others. And this is the continuing dilemma, no electronics manufacturer or design company will ever release the actual causes or rates of failures that their products have seen in the field without a court order. Instead most are turned off because the replaced by something much more capable with more features or benefits.

Hi Kirk, I consider three classes or sources of product failures, all of which we have an interesting in estimating. Notify me of new posts by email. Fred you make some very good 6109, especially about the inaccuracies and invalidity of Mil handbook book and its progeny. We need to make decisions today about design and assembly decisions that may impact product performance 20 years in the future.
