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。

I decided to use urethane foam. I used 1" and 2" thick slabs of this foam, built up to fit the cover recess area and hot-melt glued together. I built up "shelves" as the plans recommended to support the foam, and then sanded the outside of the foam to match the shape of the fuselage bottom and the NACA air scoop.

我决定使用聚氨酯泡沫，我用1 "和2 "厚砖，这泡沫，建立起以适应封面休会面积和热熔粘在一起，我建立起来的"货架"作为计划的建议，支持泡沫，然后用砂纸外面的泡沫，以配合形状的机身底部和naca空气勺子。
