2Ag (138jC), and Sn– In (120jC). The NCMS Lead-Free Project member companies selected solders with liquidus temperatures less than 225jC and with a pasty range (the diﬀerence between liquidus and solidus temperatures) to less than 30jC. The IDEALS and NEMI projects limited its candidate solders to eutectic and near eutectic, Sn-rich solders. For Sn-rich solders, a simple linear equation can be used to estimate the change in liquidus temperature with composition for additions of Ag, Bi, Cu, Ga, In, Pb, Sb, and Zn to Sn .
Production equipment and the entire basis of assembly design has been optimized for the use of Sn–Pb eutectic over the last 30 years and it is therefore important to consider to what stage lead-free implementation within a process has been achieved. An alloy selected for use with older style production equipment where good temperature control may be problematic, and, where some possibility of Pb contamination exists, may not be the optimum choice, even for an identical assembly, if the process has been initially designed to utilize energy-saving lead-free compatible production equipment, suitable components and other materials.
