Organic flip chip reliability study for space applications

The current state-of-the-art flip chip packages for space applications are the class-Y non-hermetic ceramic packages, whereas for commercial applications, organic packages have been the mainstream technology for about two decades. The high reliability of the class-Y parts suggests that the hermeticity is not critical for the reliability of flip chip devices and that organic flip chip packages could be reliable enough for space applications. The current report summarizes the result of collaboration between JPL and Cobham semiconductor space solutions to study the reliability of the organic flip chip packages.
