This work aims at numerical thermomechanical studies of two types of high temperature silver connections elaborated at low temperatures, the transient liquid phase bonding (TLPB) of Ag-In and silver nanoparticles sintering, using test vehicles representing the final packaging assemblies of diamond components. The simulation is performed using a finite element code on 2D and 3D assemblies. The stress distribution in the assemblies and in the two die-attachments was studied during thermal cycling in the range temperature between -50 and 300°C. A comparison of these two technology trends with respect to their applicability for power electronics packaging was conducted.
