"tin Coatings for Wear Resistance and Gold-like Decorative Coatings"
Titanium Nitride (TiN) coatings have led the way for providing increased wear resistance and extended life of cutting tools, whether carbide inserts or high-speed steel. Where the earliest applications were for high temperature substrate materials (carbides) and chemical vapor deposition (CVD) was the process of choice, later developments in the physical vapor deposition (PVD) technology, espec...
متن کاملEffect of Thermal Aging on the Impact Strength of Soldered Bumps under Formic Acid Atmosphere
In this study, we have investigated the effect of thermal aging on impact strength of Sn-Ag-Cu solder bumps in fluxless soldering process using formic acid atmosphere. We conducted impact tests on as-reflowed and thermally-aged solder bumps, which were fabricated on either formic acid atmosphere or a liquid flux. The results indicated that the morphology of the intermetallic compound layers in ...

Conventional soldering typically requires fluxing to promote wetting. Halogenated solvents must then be used to remove the flux residues. While such practice has been routinely accepted throughout the DOE weapons complex, new environmental laws and agreements will eventually phaseout the use of these solvents. Solvent substitution or alternative technologies must be developed to meet these rest...
متن کاملPreliminary Results of In-Vitro Skin Tissue Soldering using Gold Nanoshells and ICG Combination
Laser soldering is based on applying some soldering material (albumin) onto the approximated edges of the cut and heating the solder (and the underlying tissues) by a laser beam. Endogenous and exogenous materials such as indocyanine green (ICG) are often added to solders to enhance light absorption. Gold nanoshells are new materials which have an optical response dictated by the plasmon resona...
متن کاملFluxless Die Attach by Activated Forming Gas
Eutectic god-tin (Au80Sn20) is widely used as the die-attach material for making radio-frequency (RF) and microwave devices. The metallic bonding is typically achieved by soldering using a gold-tin preform in a forming gas containing hydrogen (H2) and nitrogen (N2) to a peak temperature at 300 ̊C. The performance and reliability of the devices are strongly dependent on the quality of the die-att...
