近年來筆記型電腦的生產己愈來愈普及,其中LCD模組占了筆記型電腦1/3的成本,而提供LCD背光的電源轉換器更直接影響了整台筆記型電腦的效率及訊號輸出品質。而目前判斷電源轉換器的品質皆以電學方法,用示波器來量測電源轉換器高壓信號,本文,從光學角度出發,用光學干涉法來分析電源轉換器品質,其所使用的方法就是利用干涉儀量測獲得高壓線路表面干涉圖形,透過表面粗糙度的分析便可判斷此電源轉換器品質的好壞。
In recent years,to produce Notebook PC becomes more and more public due its stylish design, compact size and multiple functions。 However,Liquid Crystal Display Module (LCD Mould) occupied one third of Notebook PC design and manufacture costs。 And Inverter Board provides the back light of module LCD is the key component that directly affects the signal output quality and the whole Notebook working efficiency。
The current quality judgment method for inverter board is done by using the electrical oscilloscope to measure high voltage signal。 However,in this paper,it will illustrate the use of Interferometer to analyze the inverter board quality from electro-optical view。By using the Interferometer to measure the roughness of high voltage trace of layout。The quality of inverter bard can be judged through the analysis of the roughness condition。
