High Temperature Cofired Ceramics (HTCC)

A high temperature cofired ceramic package (HTCC) is a multilayered, sealed and highly reliable package created using layers of ceramic tape with thicknesses ranging from 5 to 25 millimeters, which are laminated together. The cofired ceramic packages’ tape layers, consisting of 92 percent aluminum oxide ceramic, tungsten and molymanganese, have metallized circuit patterns. Conductive vias pierce the tape layers, forming electrical interconnects between circuits. The ceramic packages’ tape layers are laminated under pressure and the ceramic and metallization are co-sintered at 1600 degrees Celsius, creating a monolithic structure with a three dimensional wiring system.

Some advantages of using high temperature cofired ceramic packages include:

Hermeticity
Harsh environment capability
Thermal conductivity
Faster switching speeds due to shorter signal paths
Greater devise density due to more circuit layers
Resistance to thermal and mechanical shock
Improved conductor adherence to the ceramic and mechanical strength
Surface flatness
Cost competitive
Design flexibility
Mechanical strength, rigidity and non-flex

High temperature cofired ceramic package design and manufacturing requires a significant depth of knowledge in application and ceramic package design, as well as process control.
