This course provides the perfect opportunity to learn about worst case circuit analysis, its methods and its processes. The course also emphasizes the product reliability improvements that are possible when a WCCA is combined with MTBF, FMECA, and Stress and Derating analyses.

The course is designed to provide the participant with the fundamental skills and knowledge required to perform a Worst Case Circuit Analysis (WCCA or WCA). Participants learn the importance of this analysis and the different methods which can be utilized. The proper documentation format for communicating the analysis results is introduced with detailed and complete examples allowing the participant to gain a full understanding. In-depth tolerance studies and their evaluation are presented for most common electronic components.

The "WCCA Savvy Workshop" is taught personally by Charles Hymowitz (WCCA SME and one of the main authors of the Aerospace TOR on WCCA and Steve Sandler, renowned WCCA expert and founder of Analytical Engineering.

This two-day seminar is beneficial for both the novice wanting to learn worst case analysis concepts, as well as the engineering manager looking for an update on this vital technology.

Each class is specially tailored to the individuals and the disciplines (power, RF, IC) chosen by the students attending the particular seminar. Circuit examples, issues, and documentation techniques will be used that address the specific problems and pitfalls that the students are encountering in their daily jobs.

There are two versions of the class, one for Automotive Engineers and one for Aerospace Engineers. The automotive version features discussion of WCCA as it relates to ISO 26262 and ASIL Hazard analysis, features examples more in-tune with automotive circuitry, and does not include discussions of radiation effects and tolerances.

Upon completion, participants will be able to:
1. Learn the importance of why we perform a worst case analysis.
2. Learn the methods used in performing the analysis.
3. Learn the proper documentation methods.
4. Learn to deal with poorly defined tolerances.
5. Understand the challenges presented by data sheet information and how to validate key characterisits via test.
6. Understand the Requirements, Standards, and Guidelines for WCCA.
