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 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 is being taught at the Detroit location in April. 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.

Course Instructor: Steve Sandler, Founder & Chief Engineer

Steve Sandler has over 35 years of experience in the design and analysis of power conversion equipment for commercial, military and aerospace applications. In his current position, Steve is responsible for the design, worst case analysis, reliability analysis, and FMECA analysis of power electronic systems.

Steve personally designed and directed the development efforts behind AEi System's own line of space, military and commercial DC to DC converters, and developed a Power IC model library for SPICE simulators. He is the author of several books and numerous articles on power supply modeling and simulation including, "Switchmode Power Supply Simulation with PSpice".

Steve is also the founder of Picotest.com, a company that distributes test equipment including the new Signal Injector product line designed for testing linear and switching power supplies, a Test & Measurement World Magazine “Best in Test” Finalist this year. His latest book from McGra-Hill is entitled Power Integrity Measuring, Optimizing, and Troubleshooting Power Related Parameters in Electronic Systems.
