摘要

建立了热载荷作用下平板通孔(PTH)结构的数学模型，以预测其可靠性。PTH结构被视为一个系统的空心盘连接到一个桶。在载荷作用下，圆盘弯曲，枪管受到拉伸或压缩。给出了一些与失效有关的参数的简单估计公式。

Mathematical model of a plated-through-hole structure under a load induced by thermal mismatch

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.<>
