Cost Trade-offs of Constrained Sintering of Low Temperature Cofired Ceramic

摘要

In this paper, the results of a cost model study of conventional unconstrained (UCS) sintering, pressureless constrained sintering (PLAS), and pressure assisted constrained sintering (PAS) of Low Temperature Cofired Ceramic (LTCC) for applications in automotive, wireless telecommunications and consumer applications are reviewed. Results include a discussion of key assumptions and a sensitivity analysis performed to determine how assumptions influenced cost for each process. These results identify cost drivers, and suggest opportunities for improving the cost effectiveness of each process.
