Lead-Free Electronics: A Reliability Update
Keywords: Lead-free, Reliability, RoHS
Available lead-free materials and their associated reliability are changing rapidly as the search for drop-in replacements for tin-lead solders and termination finishes. There are a number of studies looking at the basic mechanisms of tin whisker growth, whisker mitigation methodologies, and tin plague. The DOD and industry groups have or are developing standards for the use of lead free materials in server service long life high reliability applications. This paper will summarize the current situation and what can be expected in the near future.
