Using Plastic Encapsulated Microcircuits in High Reliability Applications

L. Condra, G. Kromholtz, M. Pecht and E. Hakim


This paper describes technical and management aspects of using plastic-encapsulated microcircuit (PEM's) in applications in which military, hermetic microcircuits have traditionally been required. In order to implement the use of PEM's in such applications, it is necessary to re-evaluate the entire systems of qualifying, procuring, using, and ensuring reliability of parts, and of the products in which they are used. Technically, the disciplines of reliability, accelerated testing, design of experiments, and physics of failure must be used as a comprehensive of set of tools to implement and manage the use of PEM'S. Finally, an effective and efficient system for collecting and analyzing data must be set up to provide information for rational decision-making.
