Reliability Concerns of Lead-free Solder Use in Aerospace Applications

In this paper, it has been provided the impact of lead free solder use in electronics to the aerospace electronics in the aerospace environment. These impacts especially have been faced in the areas of reliability, assembly methods, cost drivers, supply chain management, and alternative materials selection. Reliability will probably be the most significant factor for the aerospace industry if it converts to Pb free. So, the question has been addressed by focusing in the reliability issues in this paper. Some information has been summarized from other studies to give an idea and references.
