In this paper, the bump patterns for flip-chip packages are discussed first, then an experiment is setup to study the dispensing phenomena for different bump patterns, and the CAE software is used to analyze and identify with experiment mutually. From these thorough comparisons and analytical analysis, the existence of channel could slow down the flow, the high density of bump could speed up the flow, and it could avoid the air trap by modified the bump and channel's arrangement on flip-chip package. Then flows in rectangular microchannels driven by capillary force and gravity are discussed; furthermore, the theoretical model of flow in microchannel driven by capillary force and gravity is formulated from the Navier-Stokes equations.

本文首先针对覆晶底部充填进行相关理论推导、实验与模拟，探讨不同凸块配置模型所造成的波前不平滑现象对底部充填流动的影响；即依据相关参数建立模型进行底部充填实验，同时以CAE(Computer-Aided Engineering)模流分析软体进行模拟，在完成理论探讨、实验与模拟分析之后，交叉比较理论、实验与模拟分析结果，归纳出影响底胶充填流动之因素，由结果显示在凸块密集度较高的区域，凸块可以帮助流动，但是在凸块区后方的沟槽区域则因为凸块区所提供之流量不足，所以会造成波前落后的现象，另外藉由修改凸块与沟槽配置的关系，可以有效的控制波前形状的变化情形，避免产生包风现象。

Such parameters as the percentage of ordinary reinforcment, amounts and configuration of unbonded prestressed tendons, the ratio of span to depth and the loading patterns were considered. Based on the results, the fomula for the eqivalent length of deformation zone on the beams at ultimate were developed. A simple formula was developed for the ultimate mid-span deflection of concrete beams with concept of equivalent length of deformation zone, and the deformation of beam before internal reinforcement yielding was predicted by the traditional formula for the deformation of partically prestressed concrete beam. Then an analytical model was deduced for analyzing the ultimate stress increment in those concrete beams prestressed with external or internal unbonded tendons based on the mid-span deflection.(4) Testes were carried out on a thin-walled concrete box beam presressed with external CFRP tendons to study its short-term performances under uniform load, long-term behaviors under uniform load, and full-time performance under four-point load in turn.
