一、热设计的基础 1、电子仪器及无部件的发展动向众所周知,电子元部件和电子仪器越來越向小型、轻量和高密度组装方向发展。电子仪器的小型化主要是由于电子元部件的小型化,特别是由于某些元部件的集成电路化所带来的结果。尤其是集成电路(IC)制造技术的进步,集成度愈来愈高。到70年代元件数为1000个以上的大规模集成电路(LSI)已研制成功并提供实用
First, the basis of thermal design 1, the development trend of electronic equipment and no components As we all know, electronic components and electronic devices more and more to small, lightweight and high-density assembly direction. The miniaturization of electronic devices is mainly due to the miniaturization of electronic components, especially as a result of the integrated circuitization of certain components. In particular, advances in integrated circuit (IC) manufacturing technology are becoming more and more integrated. Large-scale integrated circuits (LSIs), which have more than 1000 components in the 1970s, have been developed and are practical
