Electronic Part Obsolescence Forecasting, Mitigation and Management

This course is offered as: 

The rapid growth of the electronics industry has spurred dramatic changes in the electronic parts that comprise the products and systems that the public buys.  Increases in speed, reductions in feature size and supply voltage, and changes in interconnection and packaging technologies are becoming events that occur nearly monthly.  Consequently, many of the electronic parts that compose a product have a life cycle that is significantly shorter than the life cycle of the product they go into.  A part becomes obsolete when it is no longer manufactured, either because demand has dropped to low enough levels that it is not practical for manufacturers to continue to make it, or because the materials or technologies necessary to produce it are no longer available.

If a product requires a long application life, then a parts obsolescence management strategy may be required.  Many obsolescence mitigation approaches have been proposed and are being used.  These approaches include: lifetime or last time buys, part substitution, and redesign.  Several other mitigation approaches are also practical in some situations: aftermarket sources, emulation, reclaim, and uprating.  This course reviews the various mitigation approaches, and available methods of forecasting the obsolescence of parts.  In addition, pro-active methods for managing obsolescence are discussed, including design refresh planning and the use of ASICs.  The course is divided into the following sections:

The course includes a review of commercial databases and associated decision support tool offerings.  A detailed outline of the course and list of previous course offerings is available here.  Contact Peter Sandborn at CALCE for more information.


Electronic Product and System Cost Analysis Course

This course is offered as: 

The objective of this course is to provide students with an in-depth understanding of the process of predicting the cost of systems. Elements of traditional engineering economics are melded with manufacturing process modeling, life cycle cost management concepts, and selected concepts from environmental life cycle cost assessment to form a practical foundation for predicting the real cost of electronic products.

Various manufacturing cost analysis methods are included in the course: process-flow, parametric, cost-of-ownership, and activity based costing. The effects of learning curves, data uncertainty, test and rework processes, and defects are considered in conjunction with these methodologies. In addition to manufacturing processes, the product life cycle costs associated with design, procurement, manufacturing waste, sustainment, and end-of-life are also addressed.  This course uses real life design scenarios from integrated circuit fabrication, electronic systems assembly, substrate fabrication, and testing at various levels.

The course follows the book:

P. Sandborn, Electronic Systems Cost Modeling, World Scientific, Singapore, 2012.

The outline of the course is:
