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.
