Process Development for Lead-Free Selective Soldering

摘要

This investigation identifies and characterizes the critical parameters that arc involved in the selective soldering process. In this paper, the various process steps including fluxing, preheating and soldering will be discussed with respect to the lead-free process, and compared/contrasted to wave soldering where possible, to illustrate differences as well as similarities. This paper concludes that selective lead-free soldering is technologically feasible.
