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

Description
Fundamentals of Derating
podcast episode with speaker Fred Schenkelberg
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.
This Accendo Reliability webinar was originally broadcast on 13 May 2025.
