Often we do not have time for this approach. Yes, it takes work In order to predict 6709 future, the best way is to wait and measure it. The faster, easier way to work with standards. Click to learn more. 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.

You may find similar items within these categories by selecting from the choices below:. The idea, in part, is to bridge the approach and physics of failure approach. If so, then use the best technology available. Find Similar Items This product falls into the following categories.

Reference conditions for failure rates and stress models for conversion. Most electronics do not fail.

You will notice familiar equations for electrolytic capacitor life and the Arrhenius equation, and a many more. We use cookies to make our website easier to use and to better understand your needs. You are being specifically asked for MTBF for a new product.


The causes of failures are mainly due to errors in manufacturing processes, overlooked design margins, or by use errors of customers. Accept and continue Learn more about the cookies we use and how to change your settings. 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. It may take some work.

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. Starting with an outdated model is sure way to be wrong. Notify me of follow-up comments by email.

There is work to update the standard to the G revision and is making progress. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.

I consider three classes or sources of product failures, all of which we have an interesting in estimating. What decisions are you making and are they important? The standard still uses failure rates and modifications as the structure. Sorry, your blog cannot share posts by email. 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.


Using a current physical of failure model may require some thinking, additional data and a bit of research.

The equations and data used for fitting parameters are conservative. Search all products by. 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. You have to come up with something. Worldwide Standards We can source any standard from anywhere in the world.

Most of the resources for reliability development of electronics should be on finding causes of unreliability based on real data from the field. How do you make your reliability predictions? Even 5 years is difficult. In the meantime, do not use Mil Hdbk as it is sorely out of date.
