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.

There is a smaller process window and a much narrower margin of error when creating and using lead-free reflow profiles for surface mount parts on printed circuit boards (PCBs). Solder balls, dewetting, tombstones, voids, and head-on-pillow problems will occur much more frequently because lead-free alloys behave differently than eutectic pastes. Problems are compounded due to the extra heat necessary for some lead-free pastes to reach their melting points.
Our experienced engineers and technicians can craft processes that require a variety of surface mount technology (SMT) and plated through-hole (PTH) assembly techniques. ACI can assist manufacturers that require process development with solder alloy

BANNOCKBURN, Ill., USA — The IPC Solder Products Value Council (SPVC) has published a free white paper, Analytical Procedures for Portable Lead-Free Alloy Test Data, that provides a set of test protocols for the evaluation of new lead-free alloys on the basis of their physical properties. Developed in cooperation with leading original equipment manufacturers (OEMs) and electronics manufacturing services (EMS) companies, the white paper will help the electronics assembly industry reduce the time and effort required to characterize an alloy and improve its processes without jeopardizing reliability.
