Lead-Free Rework Process For Chip Scale Packages Universal Instruments Corporation Arun Gowda, K. Srihari, Ph.D. State University of New York, Anthony
Primavera, Ph.D. Consortium Manager, Universal Instruments Corporation. Legislation against the use of lead in electronics has been the driving force behind the use of lead-free solders, surface finishes, and component lead finishes. The major concern in using lead-free solders in the assembly and rework Chip Scale Packages (CSPs) is the relatively high temperatures that the components and the boards experience. Fine-pitch CSPs have very low standoff heights following assembly making inspection and rework of these components more difficult.

Lead-Free (SAC Alloy) Through-Hole Soldering Bob Wettermann BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
