SEMINAR OBJECTIVE

This seminar combines the latest accelerated reliability development tools and the classical reliability tools into one cohesive group, enhancing the reliability and reducing the cost of the products produced using the methods. Prior to this new seminar, there was no one location to gain all of this knowledge. The instructors are Gregg K. Hobbs, Ph.D., P.E., the inventor of HALT and HASS, and Chet Haibel, Master of Engineering, CRE and CQ Mgr. Both instructors are eminently qualified in their fields and together they bring synergism to the reliability arena.

BACKGROUND

In an effort to develop effective reliability programs with HALT (Highly Accelerated Life Tests) and HASS (Highly Accelerated Stress Screens) as the cornerstone, many engineers are forgetting (or never learned) some of the basic building block analysis and test tools for HALT and HASS. This seminar offers an understanding of several key tools used in conjunction with HALT in addition to a thorough teaching of HALT and HASS. Reliability Predictions and Modeling, Derating Analysis, Failure Modes Effects and Criticality Analysis (FMECA), Failure Reporting Analysis and Corrective Action Systems (FRACAS) and Reliability Demonstration Tests (RDTs). This seminar will demonstrate how each contribute to learning about and improving the reliability of a product and how each can help during the planning process of a HALT and how the HALT results can be used in conjunction with the tools.

WHO SHOULD ATTEND

This seminar is intended for those who are involved in the design, analysis, test, quality and reliability of electronic, mechanical, electro-mechanical, electro-hydraulic and many other types of equipment. Participants will develop an understanding of various tools used as part of reliability analysis, accelerated reliability testing and product improvements.
