Reliability of IGBT power modules is crucial to their use in failure critical systems and with the advent of all electric and hybrid vehicles the need for good reliability data for IGBT modules is essential. IGBT power modules are constructed of layers and power dies, all of which are interconnected with solder or bond wires. These materials have dissimilar coefficients of thermal expansion and during...
The use of IGBT power modules in the automotive industry is becoming more and more common due to the increase in hybrid and all electric vehicles. But, unlike industrial applications the duty cycle or usage of such devices due to the environment or operating requirement is very random and not well defined. This makes predicting when the device will fail very difficult as the life of the device is...
