| 中文摘要: |
| 随着大功率LED向高电流密度、高光通量发展,热流密度猛增使得LED散热问题日益严重。封装基板对LED的散热至关重要。在简介LED的封装结构及散热方式的基础上,分析总结了常见封装基板材料的性能参数,并对目前市场常见封装基板MCPCB、DBC、DAB、DPC、LTCC、HTCC、Al/SiC以及最近出现的新型材料基板的特征、制造工艺、应用等进行了综述。 |
| 英文摘要: |
| As the current density and light flux of high-power LED become higher and higher, the heat dissipation for high-power LED is becoming more and more important. The packaging substrate is a crucial channel for heat dissipation in LED lighting. In this paper, the structure of LED packaging and heat dissipation characteristics of LED are introduced briefly. The performance of some packaging substrate materials is summarized. Finally, the characte-ristic, manufacturing processes, applications of common substrates, such as MCPCB, DBC, DAB, DPC, LTCC, HTCC, Al/SiC, as well as the new kinds of substrate materials are reviewed respectively. |
