An environmental qualification of a hybrid technology for satellite applications is presented. It is based on low temperature cofired ceramics modules attached in a surface mount technology to a mother board on an aluminum base plate. For the module assembly flip-chip mounting using ultrasonic and thermocompression bonding is considered. As a validation the circuits are exposed to numerous mechanical and thermal testing procedures. In two qualification steps the different manufacturing methods are evaluated and discussed.
