Abstract :
A mathematical model simulating a plated-through-hole (PTH) structure under a thermal load is proposed to predict its reliability. The PTH structure is treated as a system of hollow disks joined to a barrel. Under the load, the disks respond with bending and the barrel undergoes tension or compression. Simple formulas for estimation of some parameters correlating with failures are presented
