In this study, varying amounts of Ni-CNTs were incorporated into the Sn-Ag-Cu matrix to form the composite solders. The interfacial intermetallic thickness formed on the Ni/Au metallized Cu substrate was determined under the as-soldered and isothermally aged (at 150°C for up to 42 days) conditions. The results of the interfacial intermetallic thickness showed that for the case of the unreinforced...
In this work, varying weight percentages of Ni-coated CNTs (Ni-CNTs) were incorporated into the Sn-Ag-Cu matrix to develop composite solders. The samples were extruded and characterized in terms of their thermal, wettability, microstructural, tensile and nano-mechanical properties. Our characterization results established that the composite technology coupled with nanotechnology in electronic solders...
Summary form only given. The goal of producing THz radiation from miniature electron beam devices has refocused interest in orotrons. Here we consider planar orotrons driven by electron beams produced by carbon nanotube cathodes. The efficiency of these devices improves with increasing current density. However, with increasing current density, self-fields become more important. Here, the theory of...
