Efficient Thermomechanical Reliability Model for Lead-Free Solder Joints
This study aims to present a new analytical model that accounts for the shape of solder joints, with a special emphasis on the determination of the mechanical properties of the Printed Circuit Boards (PCBs) and components. A simplified elastic-plastic constitutive relationship coupled with a viscoplastic model is used.
