Abstract: The European Commission (EC) directive on the Restriction of Hazardous Substances (RoHS) has sparked a worldwide race for transitioning to lead-free manufacturing. Electronics Manufacturing Service (EMS) providers in the United States have been in the process of converting to lead-free manufacturing before the July 1, 2006 deadline. A lot of research has been done and results have been published for virtually all aspects of lead-free manufacturing. These results can at times be confusing from a practical implementation standpoint. The lack of firm guidelines from the European Union (EU) for RoHS compliancy makes the transition even more challenging. In view of this uncertainty, it is necessary to interpret available literature and apply the relevant knowledge for a particular application of interest. This paper describes the implementation of lead-free manufacturing in a Contract Electronics Manufacturing (CEM) environment. Different researches are cited and a brief description of how these results can be used for the lead-free transition is provided. The process for lead-free transition is approached from a materials, process and logistical perspective to enable a systematic and timely switch to lead-free manufacturing and RoHS compliancy.
