Abstract: | Thermal management is one of key technologies of high-power LED packaging, and heat spreader will directly affect the performance and reliability of LED devices. In this work, the status and development of heat spreaders for LED packaging was introduced. Some heat spreaders including resin substrates, metal substrates, ceramic substrates and silicon substrates were compared in the structural characteristics, thermal conductivity and packaging applications. Moreover, the development trend and problems to be solved of packaging substrates for LED were pointed out. |
