Abstract

Purpose This paper aims to compare and evaluate the influence of package designs and characteristics on the mechanical reliability of electronic assemblies when subjected to harmonic vibrations. Design/methodology/approach Using finite element analysis (FEA), the effect of package design-related parameters, including the interconnect array configuration, i.e. full vs perimeter, and package size, on solder mechanical stresses are fully addressed. Findings The results of FEA simulations revealed that the number of solder rows or columns available in the array, could significantly affect solder stresses. In addition, smaller packages result in lower solder stresses and differing distributions. Originality/value In literature, there are no papers that discuss the effect of solder array layout on electronic packages vibration reliability. In addition, general rules for designing electronic assemblies subjected to harmonic vibration loadings are proposed in this paper.

振动条件下全周阵列对电子组件机械可靠性影响的数值研究

目的本文旨在比较和评估在谐波振动下，封装设计和特性对电子组件机械可靠性的影响。设计/方法/方法使用有限元分析（FEA），充分解决了封装设计相关参数对焊料机械应力的影响，包括互连阵列配置，即全周长与周长以及封装尺寸。结果有限元分析模拟结果表明，阵列中可用的焊料行或列的数量可能会显著影响焊料应力。此外，更小的封装导致更低的焊接应力和不同的分布。原创性/价值在文献中，没有论文讨论焊料阵列布局对电子封装振动可靠性的影响。此外，本文还提出了在谐波振动载荷作用下设计电子组件的一般规则。
