Accurate and useful predictions cannot be done for most causes of early life failures in electronics and we must educate those that still believe it can be and keep asking for MTBF predictions. Find Similar Items This product falls into the following categories.
You have to come up with something. How successful are you? The causes of failures are mainly due to errors in manufacturing processes, overlooked design margins, or by use errors of customers. 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 iwc assembly.

Supplier and assembly faults Overstress faults Ief out faults As lec product that has been out there for some time experiences is a rate of occurrence of all of these types of faults. Ice models are wrong, some are useful.
Predicting the future, including failure rates of electronic products with no moving parts, would be extremely valuable if it could be done. What iex are you making and are they important?
The problem is more fundamental that accurate models of intrinsic physics of failures of components. And this is the continuing dilemma, no electronics manufacturer or design company will ever release the actual iecc or rates of failures that their products have seen in the field without a court order.
The equations and data used for fitting parameters are conservative. Using a current physical of failure model may require some thinking, additional data and a bit of research.
Downside, not widely accepted in the contracting world. Worldwide Standards We can source any standard from anywhere in the world. The IEC Rev 2.
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.

You may find similar items within these categories by selecting from the choices below:. 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.
BS EN 61709:2017
So, why the article on predicting MTBF? You will notice familiar equations for electrolytic capacitor life and the Arrhenius equation, and a many more. Please download Chrome or Firefox uec view our browser tips.
I consider three classes or sources of product failures, all of which we have an interesting in estimating. Most of the resources for reliability development of electronics should be on finding causes of unreliability based on real data from the field. Hi Kirk, I consider three classes or sources of product failures, all of which we have an interesting in estimating.
Sorry, your blog cannot share posts by email. The only way this ief be shown to be true is by having many electronic companies disclose the actual causes of most of their failures in the early jec of use. The faster, easier way to work with standards.
Reliabilty Predictions – No MTBF
