Capillary phenomena was studied and discussed by the scholars about 200 years ago, but the progress was slow due to the limited equipments and manufacture precision of the microchannel.In recent years, because of the rapid development of MEMS and micromachining, many applications of the capillary flow is widely developing in some modern processes, such as underfilling of flip chip, flow in microfluidic chip or biochip, and a variety of other fields.

摘要 毛细现象大约在200年前便断断续续被欧美学者所研究讨论，但由於当时微细加工受到仪器设备和制造精度的限制，因此发展极为缓慢；近年来由於微机电系统与微细加工之精进，许多具有微流道的应用设备，陆续被制作问世，加上光学显微镜与影像撷取设备的普遍，对於研究此课题的推展极有助益；且随著微生医、覆晶底胶充填与微流体系统等领域之受到重视，毛细现象导致的充填问题、驱动原理及液体流动的控制，都变得相当的重要；本研究基於如此的动机与目的，进行微流道内液体之毛细流动现象及时间的探讨。

On the basis of the summarization of MCM-Cs main features and its assembly and packaging technologies, the paper puts stress on relatively deepgoing studies in practically advanced MCM-C assembly process technologies as gold ball wire bonding, IC chip gold ball stud bump making, IC flip chip bonding and underfilling, in high reliability MCM-C packaging process technologies as integral LTCC substrate packaging, hermetically metal sealing, and also in the basic technological process of MCM-C assembly and packaging. Later on, it presents the effectively engineering development of two high level actual module products--a high-density monolithic processor system MCM-C , a high-speed data collecting and processing system MCM-C. Lastly, it briefly introduces various common methods of quality inspection and reliability test of MCM-C assembly and packaging in engineering practice.
