dc.description.abstract	本論文中，我們以高功率紅外線光源擬似熱源，建立出一套新的熱阻量測系統。此量測系統藉由紅外線熱像儀量測溫度，並求得待測物之熱阻，本論文中以此系統針對各種目前市面上可獲得不同之LED封裝基板做熱阻量測，並與有限元素分析法建立之模型得到理想熱阻值加以比照。另外針對同一製程的基板和晶片不同bonding在基板上之熱阻表現可由實驗結果與模擬結果相互比對以推估不同基板之接面熱阻值。	zh_TW
dc.description.abstract	In this thesis, we used a high power infrared light source to emulate the heat source and built a novel system for thermal resistance measurement. In this system, a thermal camera is used to measure the temperature distribution. With the temperature distribution over the entire sample measured, we can obtain the thermal resistance of the test sample. All commercially available high power LED packages’ thermal resistances were measured based on the system that we constructed. The measurement results were compared with theoretical models which base on the finite element analysis method. Contact thermal resistance can also be estimated by comparing the experimental measurement results with the FEA simulation results. A brief discussion was provided about the contact thermal resistance contributed by different bonding methods which using different bonding material based on the analysis developed.	en_US
