| Abstract: | Plastic Encapsulated Microcircuits(PEMs) have been used gradually in military and space applications in order to meet the high performance needs of space systems.The advantage of using PEMs is the increased functionality,the speed of the instrument,smaller size,less power consuming and lower cost compared to the space Rad-Hard components.This paper analyses the problems and risks of PEMs components in space application,discusses the space environment where PEMs work,the thermal and radiation environment,and the radiation effect,Total Ionizing Dose(TID),Single Event Effect(SEE) and Electrostatic Discharge(ESD).Through the several measures such as screening,redundant design and radiation-hardened design,PEMs can be used to meet the requirements of high performance for spacecraft.Some experiment results are given. |
| Keywords: | spacecraft PEMs space environment radiation effect screening |
