All models are wrong, some are useful. You may experience issues viewing this site in Internet Explorer 9, 10 or Often we do not have time for this approach. Notify me of follow-up comments by email. I consider three classes or sources of product failures, all of which we have an interesting in estimating. The IEC Rev 2. Supplier and assembly faults Overstress faults Wear out faults As any product that has been out there for some time experiences is a rate of occurrence of all of these types of faults.

While not a full textbook, it make a major step forward.

Because of the lack of distributed knowledge on causes of real warranty failures the belief and decades long kec that the rates of failures of electronics with no moving parts can be predicted. Yes, it takes work In order to predict the future, the best way is to wait and measure it. So, why the article on predicting MTBF?

The problem is more fundamental that accurate models of intrinsic physics of failures of components. Most of the resources iex reliability development of electronics should be on finding causes of unreliability based on real data from the field. Please download Chrome or Firefox or view our browser tips. There may be others.

The faster, easier way to work with standards. If so, then use the best technology available. It may take some work. While limited in scope and using simplistic model, it provides a means for vendors to conduct and report product testing that user may convert to their specific use conditions. 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 manufacturing processes at many levels of assembly.

We need to make idc today about design and assembly decisions that may impact product performance 20 years in the future. Using a current physical of failure model may require some thinking, additional data and a bit of research.

Most electronics do not fail. Sorry, your blog cannot share posts by email. Instead most are turned off because the replaced by something much more capable with more features or benefits.

And this is the continuing dilemma, no electronics manufacturer or design ief will ever release the actual causes or rates of failures that their products have seen in the field without a court order.

You are being specifically asked for MTBF for a new product.

You have to come up with something. How successful are you? As any product that has been out there for some time experiences is a rate of occurrence of all of these types of faults.
