Influence of Climatic Cycles on Properties of Leadfree Solders

Abstract

This paper presents complex climatic tests performed in the laboratory of climatechnology of the Department of Electrotechnology. More specifically, it presents the results of climatic shocks administered to specimens of Sn-Pb and leadfree solders, and compares the results.While the experimental results are negative regarding the use of electrical resistance as a method for tracking degradation of the joints, the research has provided a large number of specimens that can be examined for structural changes in the solder after climatic stress.
