This paper presents a thermo-mechanical reliability investigation of two epoxy-filled via structures, Via-in-Pad Plated over (VIPPO) vias and the stacked microvias, combining finite element analysis (FEA) with experimental failure analysis. For VIPPO structures, pad crater susceptibility after reflow exposure was assessed using the first principal stress within the prepreg laminate, while for stacked microvias
