Tin-lead Component Projections

Can you provide a rough estimate for the percentage of current and future tin-lead finish components that will be required for the aerospace and defense industries?

Expert Panel Responses

It seems that the Aerospace and Defense Industry will continue to use tin-lead processes & components at least until 2019. Last year, members of the Aerospace Industries Association (AIA) gathered to develop a road map for the implementation of a lead-free process for Aerospace & Defense. Since this is just the early stages of the process I'm afraid I cannot make any predictions as far as materials or future technologies.
