Analysis of Direct-Soldered Power Module / Heat Sink Thermal Interface for Electric Vehicle Applications
… interface typically contains a large number of voids, which results in local hot spots. This thesis describes approaches taken to reduce voids in the solder layer through surface treatment, solder paste selection, and adjustment in solder-reflow conditions. A 15MHz scanning acoustic microscope …

Nanomaterial-Enabled Out-of-Autoclave and Out-of-Oven Manufacturing of Fiber Reinforced Polymer Composites
… thermoplastic polymer) in the prepreg and remove voids throughout the laminate. In this thesis, curing of autoclave-grade thermosetting prepregs using vacuum-bag only (VBO) processes are investigated and further developed through the employment of nanomaterials, both within the laminate itself and …

Nanomaterial-enabled manufacturing for next-generation multifunctional advanced composite prepreg laminate architectures
… in addition to vacuum, to create high-quality, void (defect)- free, reproducible structures. Carbon (micro) fiber reinforced polymer (CFRP) composites, which are pre-impregnated with a thermoset or thermoplastic polymer to form prepreg sheets, are in widespread use via autoclave processing due …
