中文摘要
本論文主要在探討光塞取多工器模組(OADM，Optical Add & Drop Multiplex)，經錫銲固化後歷經高溫老化(Aging)及熱循環(Thermal Cycling Test)過程中，其銲域殘留應力分佈、耦合位置角度變化與光訊號強度衰減關係。
文中利用MARC有限元素程式中之熱、彈、塑模式，配合銲材高溫潛變效應，建立光塞取多工器模組之有限元素分析模式，並配合各種不同具時變特性之材料參數函數，進行殘留應力分佈與變形之數值模擬分析。文中分別就不同偏位角度、不同銲錫材料(63Sn/37Pb及無鉛之96.5Sn/3.5Ag)諸封裝參數，探討光塞取多工器模組在歷經銲錫固化、高溫老化與週期性熱負載過程中，組件間因位移、角度變形對光訊號耦合效率之影響。文中並對光塞取多工器於不完美銲接條件下，其銲域所存在之空隙對偏位角度與殘留應力分佈的影響，及其衍生的訊號衰減，進行數值模擬與實驗值比較。結果顯示文中所提數值解析模式具實用性。

Abstract
The effects of residual stresses distribution and post-weld-shift on the signal coupling efficiency of an Optical Add & Drop Multiplex (OADM) are investigated in this thesis. The position variations between the two collimators in the OADM under the temperature cycling test and high temperature aging test have been simulated and studied.
The finite element method package, i.e. MARC, is used for the stresses and deformation simulations of an OADM under different load cases. The coupled thermal-elastic-plastic model is employed in the analysis, and the creep effect of the solder is considered in the numerical simulations. The temperature dependent material properties of the 63Sn/37Pb and 96.5Sn/3.5Ag solder are used for the solder solidification, temperature cycling and aging tests. The effects of the OADM packaging parameters, i.e. the different offset angles between collimators, different solder are also studied. Besides, the same simulation and analysis has also applied on the soldering with and without cavity. A comparison between the simulated and measured results indicates that the proposed finite element model is feasible for analyzing the OADM packaging problems.
