High-Reliability Solder Alloys’ Impact on Pb-free TF Conductors

The main objective of this paper was to identify a solder (specifically Sn-based and high reliability) and thick film combination to improve overall reliability of thick film hybrids. This was done by conducting rigorous thermal testing. The work conducted for this paper served as an initial exploration into this area of study.
