Ceramic Cavity Package

Ceramic pin grid array packages cpga cpgas are typically a square ceramic multilayer package with an array of pins brazed onto either the front side of the package cavity down or on the backside of the package cavity up.

Ceramic cavity package.

Hermetic or vacuum sealing is typically applied to ensure device quality. Kyocera provides miniaturized surface mount ceramic packages with cavity structures available on both top and bottom. The traditional package for rf power transistors is the air cavity package with a ceramic lid. Packages are available in surface mount designs as well as bolt down versions in dozens of open tooled designs.

Cupack packages unique design with very low thermal resistance. Available in larger sizes up to a cavity of 16 5 mm x 6 1 mm ni780 header unmetallized frames enable shorter lead times and reduce manufacturing complexity. The flange or heatsink material has evolved over the years and the most commonly used material today is cpc cu mo70cu cu a laminate of copper and coppermolybdenum. Ceramic air cavity packages proven performance for wireless applications.

Air cavity type hermetic package close thermal expansion matching provides superior mechanical elasticity and less mechanical stress with silicon mems chips miniaturized high density surface mountable package incorporating multi layer ceramic technology.
