LSU Doctoral Dissertations
Nonaqueous electrolytes play an important role in electrochemical devices such as flip chip and lithium-air batteries. In this work, we examine ammonium-Cu, Sn and Li interactions in nonaqueous electrolytes to optimize the future flip chip flux and electrolyte additive of lithium-air battery. The activity of halogen-free carboxylic acid flux is considered one of the most important aspects in controlling flip chip joint quality recently. CuOx removal effectiveness of carboxylic acid solutions at Cu substrates using electrochemical methods at elevated temperatures from 100ºC to 180ºC is studied thoroughly by chronopotentiometry and gravimetric analysis. Carboxylic acid-based solutions with ethanolamine show oxide removal …
