The thermal reliability research of the data processing PCB of CCD control system in the space remote sensor
2008
The reliability of the space optical remote sensor is very essential and important. The reliability of electronic equipments in the space optical remote sensor affects its reliability greatly. Electronic equipments,specially the avionic equipments become gradually smaller. Because of the small volume and compact arrangement,heat flow density of equipments is sharply increased and the reliabili-ty is greatly reduced. In this paper the heat transfer principle is introduced briefly. Temperature field of the data processing PCB of CCD Imaging system in a space remote sensor is analyzed by ICEPAK,and the optimal design is proposed. The reliability of the electronic system is well improved.The analysis and plan is well used in the engineering project.
