Tolerance specification communicates the allowance for part variation. Variation happens, and when it is within what we expect, great.

This chapter explores the significance of derating in electrical engineering, emphasizing its role in enhancing the reliability and lifespan of electronic components. It also contrasts derating practices in electrical and mechanical engineering, detailing personal experiences and examining various failure mechanisms that inform effective strategies.
This one is for those involved with the design of electronics. Clustering a few standard components is a standard way to bring functionality to your product, yet considering how those components may fail is important to create a robust and reliability product.
Derating is the method of selecting components with sufficient rating to withstand variations in stress(es) they may experience. Let's explore why derating is important, the difference it can make, and a few methods to implement derating with your design team.

Tolerance specification communicates the allowance for part variation. Variation happens, and when it is within what we expect, great.
Early and often during product development, the team needs to know the expected and meaningful reliability prediction of the current design.
One of the challenges for reliability engineering in product development is reliability integration into the product development process.
How a focus on variability with process control, process capability and tolerances helps to improve reliability.
How a focus on variability with process control, process capability and tolerances helps to improve reliability.
If a person is not able to interact with your product, with or without the manual, they may consider your product a failure.
How to find and analyze temperature readings over a 10 year period, create histogram and determine how many hours below freezing may exist.
There are three approaches to set tolerance limits. Each has ramifications for the eventual manufacturability and reliability performance.
Warranty returns are a great start for setting targets for new products. But how do you translate that to specific numbers to design to?
DFR is more than a set of tools or activities, let's explore the building of a reliability culture that support reliability thinking
Fault tolerant design principles are the best approach to reliability. Or not. It depends on your design challenges.
Besides building your product inside your customer's facility, your product requires transportation to move your product.
This webinar introduces you to the topic of reliability growth (both qualitative and quantitative) along with key concepts
I will discuss the identification of conditions that cause materials to degrade. Understanding stressors is good for design for reliability
