Simulation optimized design for vibration resistant Power module package

IGBT based power modules designed for usual industrial application cannot be transferred without changes to a Commercial, Agriculture and Construction Vehicles (CAV) application. This is because of the higher overall system requirements such as of vibrational harshness. This paper describes the simulation flow to construct a more vibration resistant power module for CAV applications. Vibration simulation (modal and harmonic analysis) is a faster and more effective method for optimization of a design concept rather than using hit and trial methods. Optimization of the package initiates with the evaluation of mechanical behaviour under a set of vibration load characteristics for new applications. Designs which meet the vibration criteria were further analyzed for suitable thermal behaviour. Such a design flow leads to a thermally feasible and mechanically optimized component for CAV applications.
