Subject: ESS for electronics components
I have following questions.
1. During the burn-in tests of electronic modules do the units have to be powered up? Is there some literature that explains the principles of burn -in for electronics?
2. Where can I find the temperature and cycling guidelines including acceptable ramp rates for temperature during burn-in process?

Question #1: No, the units do not have to be powered up, but the screen is more effective if the units being screened are under power. A good starting point to begin your reading on the subject would be "Management and Technical Guidelines for the ESS Process" published by Institute of Environmental Sciences and Technology (IEST), Product Reliability Division. The document number is IEST-RP-PR001.1. Their website is www.iest.org. Question #2: Another good reference is the RAC Reliability Toolkit: Commercial Practices Edition. Section 7.5 talks about ESS and has a table showing baseline temperature ramp rates. Good luck.
