dc.description.abstract綜觀市面上眾家應用於影像感測、擷取之影像模組,皆已逐漸朝向體積變小、效能更為提升的研究方向發展。如何在有效的使用空間下,達到符合產品需求的最佳化設計值,將是未來產品開發的趨勢。在現階段影像模組的開發過程中,電子設計工程師往往只考慮信號傳輸的正確性及效能上的補償功能,因此在電路板的排版過程中,加入了越來越多的穩壓電路、控制晶體及走線。但在遷就了電路控制上的考量後,幾乎已將一塊像火柴盒尺寸般的印刷電路板上塞滿了零件,而此舉卻忽視了眾多零件耗能所帶來的“熱”影響。 本論文利用紅外線熱影像分析影像模組的電路板之溫度分佈,藉由零件溫度的高低歸納出主要的熱源所在,再依此分成兩大項研究。首先針對溫度高的位置設置排除熱能的散熱機構,並探討散熱器對電路板散熱上的實質效益。其次是評估電路板設計上的零件位置及佈線方式,以尋求最符合電路設計之最佳化走線佈局。為了確保電路板上的影像感測器、數位訊號處理器能工作於適當的溫度範圍,本論文藉由整合熱傳分析所預設的模擬以及實際量測數據之交互驗證下,提出針對主要熱源之處可改善10 %的散熱效能之方法。zh_TW
dc.description.abstractMost commercial image modules for image sensing and capturing are developed to be small in size and have more functionalities. How to achieve the optimum design under the limited usable space is the future trend in product development. In the current development process of the image module, since an electrical engineer usually only considers the correctness of signal transmission and the compensating functionalities, more regulated-circuits, signal-controller ICs, and signal-routes are added during processing the layout of a printed circuit board (PCB). After compromising to the circuit control rules, the PCB with size like a match-box has been jammed with various electronic components. However, the heat caused by these components is totally ignored. This thesis utilizes the Infrared-Thermograph to analysis actual temperature distribution of the PCB, generalizes the main heat source from the temperatures of the components, and then divides into two research categories. First, the heat dissipation mechanisms are provided on the high temperature position of the PCB. Then, its actual heat dissipation effect is studied. Second, the position and the layout of the components are evaluated to find out the optimum layout of the PCB that fulfills the requirements of the circuit design rules. In order to guarantee the operating temperatures of the image-sensor and the DSP on the PCB to be within a suitable range, this thesis provides an improved method by alternately verifying the simulated data from the heat-transfer analysis and the actual measured data that improve 10 % heat dissipation effect of the main heat source.en_US
