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。

Kempers' study , the more layers the mesh screen type had, its resistance against gravity was higher, but its heat resistance and flow resistance were comparatively augmented. As mentioned in the preceding paragraph, it is extremely difficult for a single micro structure based on any of the three types to possess both low flow resistance and strong capillary force. Faced with this fact, the researchers have tried to mix the three micro structures in Table 2 into as many combinations as possible so that a composite micro structure with low flow resistance and great capillary force may be fabricated. After a thorough analysis, the groove combined with sintered metal or mesh screen has been found to be a better alternative. However, the groove combined with sintered metal will raise the flow resistance of the channel, and the aluminum substrate employed in this research cannot be sintered into a micro structure. As a result, the groove combined with mesh screen is finally chosen as the composite structure to enhance its capillary force and at the same time maintain its high permeability. In this way, the heat pipe will not fail due to the working angles.

Kempers 的研究当中提到，当网格结构越多层时，其对抗重力的能力也越强，但相对的其热阻以及流阻也越高，就如同前段所述，我们很难在单一结构当中找出一流阻低且毛细力之微结构；因此本研究便以表2中之三种微结构进行组合，找出一低流阻且毛细力强之复合式结构，经分析发现，沟槽搭配烧结以及沟槽搭配网格为较佳之组合方式，但由于烧结搭沟槽构造将会提高流道之流阻，且本研究使用铝做为基材，并无法使用烧结最为其微结构，故将采用网格搭配沟槽之复合式结构提高结构的毛细力，并维持沟槽结构的高渗透性，解决因角度造成热管失效的问题。
