“…In addition, the failure mechanism and optimization rule of TGV interposer architecture were systemically investigated [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Tensile radial and circumferential stresses were attributed to the origin of the circumferential cracks and the formation of radial cracks, respectively [ 11 , 13 , 14 ].…”
