Meet Student Researcher Yianni Bonincontri '28
During my time as a research assistant at the Center for Advanced Life Cycle Engineering (CALCE), I worked in electronic packaging fabrication, characterization, and failure analysis. The work involved making test samples, in which I prepared alumina substrates in and out of the UMD Fab Lab and performed die attach using tin-silver transient liquid phase sintering. Through this characterization, I evaluated voiding behavior and intermetallic compound growth. I tracked variables such as plasma etcher operational settings and substrate surface roughness. This experience provided me with an understanding of electronics manufacturing, material characterization, and packaging reliability testing.
