چکیده

A model for the theoretical description of KIRKENDALL voiding is presented based on vacancy diffusion and plastic deformation of spherical voids. We start with a phenomenological explanation of the KIRKENDALL phenomenon and discuss its consequences on microelectronic reliability. After that a constitutive model for void growth is introduced, which, for instances, can be used in order to predict the temporal development of a certain void distribution. We end this paper with exemplary numerical studies.

Effect of voids on the reliability of BGA/CSP solder joints

Voids in solder joints have been considered as a defect in electronics assembly. The factors that affect void formation are complex and involve the interaction of many factors. There are no established standards for void size and void area in a solder joint for it to be deemed defective. Inspection criteria have been very subjective. The effect of voids on the reliability of solder joint may de...

Secondary IMC formation induced by Kirkendall voiding in Cu/Sn3.5Ag solder joints

In this investigation on the formation of multiple-layered Kirkendall voids at Cu/Sn– 3.5Ag solder joints, Sn–3.5Ag solder balls were reacted with Cu under bump metallurgy (UBM), which was electroplated using bis-sodium sulfopropyl–disulfide, C6H12O6S4Na2 (SPS) additive. The sequence of multilayer Kirkendall voids and Cu–Sn IMC (intermetallic compounds) formations are explained with the aid of ...

Effect of the Formation of the Intermetallic Compounds between a Tin Bump and an Electroplated Copper Thin Film on both the Mechanical and Electrical Properties of the Jointed Structures

The mechanical and electrical reliabilities of fine bumps with diameters and heights on the order of scores of microns were studied, considering the growth of the intermetallic compound (IMC) at the interface between a tin bump and a copper thin-film interconnection. It was found that an increase in the thickness of the IMC changed the stress and strain fields around the interface significantly...

Mechanisms and solutions to the brittle solder joint in electroless Ni plating

Brittle solder joints in Electroless Ni electroless Pd immersion Au (ENEPIG) surface finishes are one of the key re­ liability issues in electronics assembly. Previous characterization of the reflow process has indicated that interfa­ cial voids formed after solder reflow are responsible for the decreases in solder joint strength. However, the mechanisms behind the formation of these voids in t...
