A Cost Model for Assessing the Transition to Lead-Free Electronics

Actions such as the WEEE Directive and RoHS Directive are forcing electronics suppliers to transition their products from tin-lead to lead-free solder in order to support consumer goods. The defense and avionics industries obtain their parts from the same suppliers and must adapt to these new lead-free products. In this thesis, a cost model was created to evaluate the transition from lead-free to tin-lead electronics. The model provides the industry with multiple transition options and determines the costs associated with each of these options. The options modeled are an all tin-lead assembly, a lead-free assembly and a mixed assembly. The cost model assimilates all the costs involved in the transition to lead-free and includes changes in reliability…
