Fatigue life prediction models developed for Green Electronics in Aeronautical and Military Communication Systems (GEAMCOS)

摘要

This paper presents in details the fatigue life prediction models developed for lead-free assemblies in harsh environments during the 3-year European LIFE project GEAMCOS. The approach uses advanced finite element modelling as well as experimental fatigue data. It is also based on a complete material characterisation for a wide range of stress conditions. It focuses on the most critical packages of the full lead-free GEAMCOS test board and of the functional demonstrator developed for military communication.
