In what follows we determine the mechanical properties of intermetallic phases in microelectronic structures with the help of nanoindentation. Additionally, we try to answer the question of whether nanoindentation can be used to quantify the growth o

To meet the state‐of‐the‐art requirements of BGA assemblies necessitates direct coupling of field conditions, simulation tools for life‐time study and advanced experiments for the assessment of physical degradation. For conventionally soldere

A study of the performance of different Sn based solder alloys applied for large to small sized solder interconnects was undertaken. From the theoretical and experimental investigations on creep, fatigue and brittle fracture behaviors the paper focus

This paper focuses on a finite element analysis of the state of stress and strain within an intermetallic layer at the interface of a lead-free solder joint. The magnitude and sign of the stresses and strains (tensile vs. compressive) is discussed as

In this paper we present our results on how nanoindentation can serve for measurement of (local) mechanical properties in microelectronic materials and components. Special attention is paid to the properties of interface regions, i.e., the region of

This paper presents lifetime predictions, based on finite element analysis (FEA), for the copper via connectors present in high density interconnectors (HDI) used for mounting of CSPs. The life-saving impact of various fillings of these connectors is
