Various myths related to EEE Components are circulating due to misunderstanding and misinterpretation. The presentation attempts to debunk 16 myths, hopefully helping the community avoid pitfalls. The myths are:
Myth 1: Incorrect interpretation of the term “Space Qualified.”
Myth 2: Incorrect interpretation of the terms “Radiation Hardened” and “Radiation Tolerant.”
Myth 3: The main drive to use COTS in space is Cost Savings.
Myth 4: Incorrect interpretation of the term “space heritage. “
Myth 5: Use of terms “Quality” and “Reliability“interchangeably.
Myth 6: COTS reliability cannot be ensured unless they are 100 percent tested and screened.
Myth 7: Meeting the absolute quantitative limit of reliability is required in technical specifications in order to achieve the needed mission reliability.
Myth 8: Plastic encapsulated semiconductors (PEM) cannot be used for space applications.
Myth 9: COTS industry is not controlled sufficiently.
Myth 10: COTS industry is not wafer traceable to ensure radiation test validity.
Myth 11: Success in space missions can be achieved only using a conservative approach.
Myth 12: Redundancy is a magic solution to enable the use of softer radiation components.
Myth 13: A meaningful barrier to using COTS in Space is the space application’s criticality.
Myth 14: The automotive grade (AEC-Q) EEE Components are recently aggressively promoted for space applications, being more reliable and having a lifetime of 15 years vs. industrial grade ones.
Myth 15: The more frequent obsolescence of COTS is a showstopper for their use in space applications.
Myth 16: Electrical and Radiation Tests at the Component level is technically justifiable to be replaced by testing at the board/module/subsystem level.
He has 44 years of experience in Component Engineering at MBT/Israeli Aerospace Industries (1969 to 2013), as Head of Components Engineering. As such, he was responsible for all aspects of EEE components – including policymaking, standardization at corporate level, approval, etc. – for military and space applications.
Now retired, Friedlander is an industry consultancy (2013 to present).
