The availability of space qualified semiconductors has, with a few notable exceptions, decreased dramatically in recent years. At the same time the commercial electronics industry has had access to ever wider ranges of component functionality and package styles. In most cases this product has only been available as COTS (Commercial off the Shelf) PEMs (Plastic Encapsulated Microcircuits). If electronic circuit designers in the space industry are to be able to make use of the ever increasing levels of functionality available in COTS PEMs consideration must be given to the usability, reliability and continuing availability (short duration obsolescence cycle) of such components. This presentation will consider some of the practical aspects of screening PEMs for use in space environments using data from recent IGG experiences with a GPS "front end chip", a "camera chip" and failure analysis work in a commercial environment. Consideration will also be given to the possibility of overcoming obsolescence problems by using "long term storage".
