Tin (Sn) metal displays the characteristic of growing “tin whiskers” from pure tin coatings (most actively on relatively thin, electrodeposited or immersion tin coatings), usually months or years from the initial deposition of the tin. Tin whiskers are electrically conductive, filamentary, single crystals of white (beta phase) tin. These filaments of single crystal tin are usually one to five microns in diameter, and a few microns up to several tens of millimeters long, that grow spontaneously from the tin coatings. Alloying additions of several percent (by weight) of lead (Pb) prevents these electrically conductive tin whiskers from growing. Pb alloyed into the Sn was discovered to prevent the occurrence of tin whiskers in electronic assemblies in the 1950s as the Bell Laboratories solution to the problem of tin whiskers. The alloying of the tin with lead has thus quietly averted incalculable losses from short circuits in electronic equipment for the last 60 years.

The SMTA Officer team is excited to provide our members with a new webinar by Dr. Nathan Blattau, R&D Fellow at Ansys, Inc., on "Next Generation Lead Free Solders for High Reliability and SMT Yield improvement in Client Computing Systems." The webinar will be on Tuesday, April 6th at 12:00 PM EST and will discuss the evolution of lead free (Pb-free) solder, from tin-silver-copper (SAC) system with silver content of 3.0 and 4.0 to low SAC solders and the emergence of high reliability Pb-free solder. It will cover the reasons and the driving forces of industries implementing this change.
