Among the various lead-free solder alloys, the National Electronics Manufacturing Initiative (NEMI) recommends Sn-3.9Ag-0.6Cu ( 0.2%) for reflow soldering (Ref 1), while JEITA (Japan Electronics and Information Technology Industries Association) recommends Sn-3.0Ag-0.5Cu. Under most typical use conditions, Sn-Ag-Cu (SAC) alloy in general exhibits a greater resistance to creep as compared to Pb-Sn alloy and hence creeps 10 to 100 times slower (Ref 2). The microstructure, the plastic and creep behavior, and the failure mechanism in Sn-Ag-Cu solder are vastly different compared to Pb-Sn solder, and therefore, it is important to develop appropriate thermomechanical predictive models for Sn-Ag-Cu solder.

While an increasing number of environmentally friendly products continue to be introduced in Japan and Europe, some North American companies have taken a wait and see approach while others are pacing themselves based on market demands and supply line availability to the lead-free issue. Many Japanese companies have adopted the use of lead-free solder and lead-free components. The use of green labels helps to promote lead-free product introduction using guidelines established by the Japan Electronics and Information Technology Industries Association (JEITA).

There continue to be perception issues over some species of flame retardants, specifically relating to persistence, bioaccumulation, and toxicity (PBT). Most of these PBT issues are legislatively mandated in the European Union (EU), but these issues are beginning to show up at the state level in the United States and at the national level in Japan and a few other Pacific Rim nations. In addition to PBT issues, there is an increased requirement for recycling plastics used in commercial products, which is most prevalent in the area of information technology equipment (ITE). ITE sale and use in the EU is covered by the Waste Electronic and Electrical Equipment (WEEE) protocol, which dictates that plastics used for ITE need to be either recycled or incinerated after use. Due to the perception issues behind halogenated flame retardants, some have been deselected for ITE applications in favor of nonhalogenated flame retardants. So with the emphasis...
