Examines effects of several process variables on lead free solder pastes. Need for a consistent joint quality across a printed circuit board (PCB) in implementation of lead-free assembly; Four variables that were tested in the examination of damage sensitivity; Two factors that limit maximum temperature that a PCB assembly can tolerate; Three problems associated with flux residues from solder materials; Relation between surface tension and solderability.
