48 Summary

Low-temperature co-fire ceramics have many attributes that meet the needs for applications ranging from simple, high-frequency, hand-held communications needs to complex switches and multichip modules that support high-performance servers and supercomputers. The advantages of the LTCC materials such as low dielectric constant and high conductivity copper conductivity provide low-cost solutions for many customers needs. LTCC processing begins with raw materials, including dielectric powders and conductive metal powders, and continues through multilayer ceramic processing, resulting in a three-dimensional array of conductive wires with a dielectric of desired properties. LTCC also can be fabricated with integrated passives and has extendability in the wiring and interconnection ground rules compared to those used today. LTCC will continue to be used in a variety of applications where it is best at meeting the cost and performance objectives sought by the customer.
