Synthesis of Nanoscale Metal Feedstock with Low-Temperature Sinterability for 3D Printing
­Background Nanoparticle-based metallic powders are of interest for rapid sintering, thermal bonding, and electrically conductive metal pastes due to its unique properties, such as lower sintering temperature compared to bulk counterparts and efficient light absorption for photonic curing. However, there are some drawbacks associated with the production,...

In Situ Electromigration Testing Fixture for X-Ray Microtomography Systems & Electron Microscopes
Electromigration is the transport of material caused by an uneven distribution of current, causing atoms to accumulate at the anode and separate from the cathode of an electronic circuit. Materials that experience electromigration undergo a complex 3D evolution, which often results in short and open circuit failures at soldering joints. Electromigration’s...

Modular High Resolution X-Ray Tomography System: Source, Sample Manipulation, Detector
High resolution x-ray tomography (XCT) provides a nondestructive approach to 3D imaging suitable for examining material microstructures. Current options for x-ray micro-tomography (µXCT) are limited to select research facilities that employ synchrotron light sources in XCT experiments, and overpriced lab-scale µXCT systems of insufficient...

Rare Earth - Containing, Pb-Free Solders with Enhanced Ductility and Oxidation Resistance
Global concerns over the environmental impacts and health effects of Pb-based solders in consumer electronics has led to the development of Pb-free solder alternatives. Among the potential alternatives for Pb-Sn solder, Sn-Ag-Cu alloy is one of the most promising as a result of its relatively low melting temperature, superior mechanical properties,...
