Abstract: Thermal design, finite element analysis of a satellite borne PCB is introduced in this paper. Some methods were adopted to help heat conduct and a simplified computing model was built. The analysis results show that the temperature scope of the main structure is from 45.5°C to 72.3°C in high temperature work case and all of junction temperatures of components are lower than the derated maximum junction temperatures themselves and leave enough design margins, which match the requirements of thermal analysis.

Abstract: The nano-composite electroless coating was introduced into bio-limited forming technology for the first time, and the feasibility of the nano-composite electroless coating on microorganism was verified. The composite coated microorganism was analyzed by using optical microscopy, scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). The results showed that stirring method would make significant effect on the content of nano-particles in the composite coating. And compared with mechanical stirring, the magnetical stirring makes the content of Fe in the composite coating increase almost twice. The co-deposition mechanism of the composite coating was also discussed.

Abstract: The connotative meaning and trend of bionic design and manufacturing was analyzed. A new bioforming technology was presented, which will offer a new way to solve the difficulties in manufacturing of bionic micro-nano structures, and the layout of bioforming technology was also plotted. Several different bioforming technologies targeting typical bionic products were introduced. Compared with traditional manufacturing methods, to machine complicated micro/nano shapes, structures, functional interfaces with bioforming technology has more advantages, which showed that bioforming technologies would have great potential applications in energy-saving, environmental protection, and micro/nano fields.
