The computer code was then applied for analysis of intermetallic layer growth from solder aging experiments performed with 100Sn and 63Sn-37Pb solders. The analysis indied that intermetallic layer growth was consistent with bulk diffusion mechanism involving Cu and (or) Sn and variable diffusion coefficients that reflect some enhanced diffusion during early growth.

Solder paste is a homogeneous and kinetically stable mixture of solder alloy powder, flux, and vehicle that is capable of forming metallurgical bonds at a set of soldering conditions and can be readily adapted to automated production in making reliable and
However, as “eutectic” (63Sn/37Pb) and tin/silver (Sn/Ag) bumps have become prevalent, water-soluble fluxes have become the standard. Note that although there are known instances where a reactive atmosphere approach may be used to reflow solder Figure 1

The results obtained affirmed that the addition of Ni and Bi in low-Ag SAC0705 solder improves the shear strength of the solder joints and decreases the fracture ductility of the alloy.
To meet nature requirements for cost, size, weight and electrical performance, microelectronic packaging is moving from wire bonds to solder bumps as the preferred method of interconnection from
