Abstract : The report summarizes the efforts expended and objectives reached in a program to establish and verify qualification procedures for hybrid microcircuits. The program was conducted in two phases. In the Study Phase, existing qualification data on hybrids were reviewed, and a series of stepped stress tests were performed on three hybrid microcircuit types. In the Verification Phase, the effectiveness of the process control and the screens established by the Study Phase were verified. The results of the program studies and evaluation led to the establishment of an optimum set of qualification procedures for in-process screening and lot qualification, and the description of cost factors involved in each in-process screen and lot qualification test for Class A, B, and C hybrids, and for various lot sizes. Information was also compiled on vendor qualification and product qualification requirements. (Author)
