BERYLLIA-CERAMIC materials have been successfully used during the last
40 years to produce reliable packaging solutions for a wide range of
commercial microelectronic packaging applications. Ceramic properties
have been well-defined and consistently controlled throughout producti
on of many millions of circuits to ensure high-performance operation a
nd product reliability. In the report that follows, the physical and e
lectrical properties of beryllia-ceramic materials will be examined, e
specially in their application for high-power RF and microwave package
