With the phasing out of lead-bearing solders, electrically conductive adhesives (ECAs) have been identified as an environmentally friendly alternative to tin/lead (Sn/Pb) solders in electronics packaging applications. Compared to Sn/Pb solders, conductive adhesive technology offers numerous advantages. However, this new technology still has reliability limitations. Two critical limitations are ...

Stainless steels have good corrosion resistance in many environments but welding or aging can decrease their resistance. This work focused on the effect of aging time and ultrasonic nano-crystal surface modification on the passivation behavior of 316L stainless steel. In the case of slightly sensitized 316L stainless steel, increasing the aging time drastically decreased the pitting potential, ...

Surface properties canmarkedly affect themechanical behavior of structural thin films used inmicroelectromechanical systems (MEMS) applications. This study highlights the striking difference in the sidewall surface morphology of n+-type polysilicon films from two popular MEMS processes and its effect on fracture and fatigue properties. The sidewall surface roughness wasmeasured using atomic for...

• Hybrid sputtering/ gas agglomeration system produces bimetallic Zn-Fe NPs as oxygen scavengers. The atomic arrangements of the allow to control oxidation mechanism. Galvanic couple between Zn –Fe accelerates process. Molecular dynamic simulations show effect galvanic for Bimetallic nanoparticles (NP) have demonstrated outstanding multifunctional characteristics, which depend on their size, di...

The paper focuses on the analysis of initiation and propagation CO 2 corrosion in several samples low-alloy steel with different microstructures using scanning electrochemical microscopy (SECM) other techniques. It is found that rate mode are highly sensitive to microstructure. overall current density much higher more uniformly distributed for tempered martensite structure than having either a ...
