Education & Seminars
Mechanical Design of IC Packaging

OBJECTIVES
Reliability techniques at the IC Packaging level are different from those at the board/system level. We shall explore the best tools and techniques to use at the IC Packaging Level.

The course is intended to provide experimental and analytical tools to engineers that evaluate the field reliability of discrete semiconductor components. The sub-discipline known as DFR (Design For Reliability) is a vital component of most modern design teams. Achieving a product's reliability goals requires the proper application of both tools and techniques.

The course covers the basics of component reliability theory and implementation for the design, quality and manufacturing engineer or manager.

Emphasis is placed on learning the proper application of each reliability tool and technique, and also on knowing when to apply each and why. The methodologies used to evaluate the failure rates for the components are based on physics of failure, when statistical tools are used in conjunction to equations describing the expected failure mechanism under use field conditions.

WHO SHOULD ATTEND
This course is intended for those individuals and managers involved in the design, test and/or analysis of discrete semiconductor components, and who wish to acquire a better understanding of current reliability concepts and practices and how their proper application leads directly to better and more reliable products.
