Ceramic Cavity Package

Cupack packages unique design with very low thermal resistance.

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. 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. 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. Kyocera provides miniaturized surface mount ceramic packages with cavity structures available on both top and bottom.

Packages are available in surface mount designs as well as bolt down versions in dozens of open tooled designs. 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. If saving time and reducing cost is important for your ceramic air cavity packages talk to one of our experts about the fully assembled ca pack package solution. The traditional package for rf power transistors is the air cavity package with a ceramic lid.

These ceramic packages are suitable for use in sensors due to the high modulus of elasticity and low coefficient of thermal expansion of ceramic materials.
