The classical module design is limited in lifetime by solder interfaces and wire bond technology. The elimination of the traditional base plate and the replacement of solder interfaces by a high reliable Ag sinter technology led to the first 100% solder free module. The SKiN technology eliminates the last obstacle to a significant lifetime and reliability improvement: the wire bonds. It additionally replaces the interface to the heat sink by an Ag sinter interconnect and thus allows a very compact and light design of power electronic systems.
