Comparing to the IMC phases existed in solder references and its morphological surface, CoSn2 particles are more coarsen compared to the IMCs of Ag3Sn and Cu6Sn5, which have finer structure and distributed uniformly; which translates in better mechanical properties of solder joints [12,13].
4.2 Composite solder
Chan et al. has reviewed the research advances of nano-composite solders that have been develop in the electronic industry [1].

This is due to the denser structure of the packaging material, higher adhesion of the laminated layer to the polypropylene substrate and the possible presence of a corrosion inhibitor.

Abstract.
These two parts are clamped in a fixture and the laser beam passes through the transparent part in which some energies are absorbed and/or scattered by pigments, reinforcements, filler and crystal structures.

Abstract.
Since the grain boundary amount is constant in the starting system, the reason of the bimodal structure observation in powder nuclei and more homogenius particle size distribution in seed containing sample is not attributed to the grain boundary phase.

Introduction
SS400 steel is a low carbon steel that commonly used for engineering structures such as bridges, buildings, and ship construction.
Microstructure evolution in the fusion zone is influenced by several factors such as chemistry of filler metal, heat input, shielding gas composition and welding method.
