Subject: Derating guidelines for SMT
I am trying to find some derating guidelines with regards to Surface Mount Technology (SMT), especially in the area of microcircuits. Are such guidelines available? In general, are there any differences between the derating factors for SMTs compared to MIL-HDBK-338? I understand that the latest derating study conducted by the former U.S Air Force Rome Lab in 1992 can be found in the technical report, RL-TR-92-11 (ADA253334). Does this study cover SMT? Please advise.Thanks.
