Previously, a Power Electronics Technology article titled “Inverted Acoustic System Cuts IGBT Failures” (September 2011) examined the use of an acoustic microscope to image heat-blocking defects such ...

Semikron has an IGBT module for 22kW to 150kW converters in electric and hybrid vehicles, which it claims is entirely solder-free. According to the supplier, this means the module can have a five ...

A lack of planarity along the interface between the solder and the ceramic raft in an IGBT module is a common anomaly that can make heat dissipation uneven across the die and cause the die to crack.
