Traditional reliability prediction method did not include the space radiation environment reliability.. 3. It’s the time to set up a method of space radiation environment reliability prediction. Speaker: QunyongWang, DongmeiChen, HuaBai, PhD Beijing San-talking Testing Engineering Academy Co., Ltd. (STEA) Space radiation environment effects Main failure modes Single Event Effect (SEE) – SEE reliability prediction method – SEE is an instantiate effect, only happens during power on time of the sensitive devices. – SEE failure rate prediction method under radiation stresses. – TID/DD reliability prediction method – Sensitive devices TID/DD failure distribution—lognormal Intrinsic radiation resistance—failure distribution parameters Case study Assume satellite to be launched in 2015，GEO，T=12 Y. • Mission space radiation stresses: TID 69.8krad, LET spectrum in figure 1 on full document. • Key sensitive device: SRAM-FPGA，TID/SEU sensitive • Ground test: 60Co TID, LINAC Heavy ion SEU λTID prediction FPGA failed TID test data • λ SEE prediction Summary • Based on space radiation failure mechanism and statistical characteristics, a method of space radiation environment reliability prediction is setup upon failure physics, which expands the application domain of reliability prediction. • To be applied on reliability design for future space vehicles.
