更加具体地说，对于具有任意复杂多变的布线和材料特点的任意形状尺寸的集成电路产品，需要高效率、高精度、全自动化地基于细观有限元方法计算任意大小分区的数十万甚至数百万个分区的等效材料性能，期刊论文4、会议论文317和331分别针对力学性能参数、化学收缩系数、热膨胀系数、热导率直接给出了具体的算法和算例。

数十万甚至数百万个分区的各种各样等效材料性能的细观有限元模拟显然是耗时的，因此基于CNN、Transformer-CNN技术的布线结构分区等效材料性能的人工智能预测技术就变得很有必要，期刊论文2、会议论文251直接给出了具体的算法和算例。

在此基础之上，具体研究了服务器主板和笔记本电脑主板的制造、回流组装芯片以及PCBA使役过程的可靠性问题，期刊论文3针对PCB压合成型、期刊论文1针对PCB压合成型/芯片封装/回流组装/PCBA使役疲劳全贯通的过程、会议论文252针对PCB压合成型及其后的铣削加工、会议论文260针对PCB制造及其后的回流组装芯片封装体直接给出了具体的算法和算例。

进一步地，开展了集成电路的晶圆级集成扇出封装WL-InFO、2.5D封装、3D封装的可靠性研究，会议论文248、会议论文263分别针对WL-InFO、2.5D封装（CoWoS - Silicon Interposer）直接给出了具体的算法和算例。因为种种原因，3D封装（HBM 3和HBM 3e）的可靠性研究内容未能参加这次的会议交流，尽管研究进展很大。
