Water Soluble Solder Paste, Wet Behind the Ears or Wave of the Future


Water soluble lead-free solder paste is widely used in today's SMT processes, but the industry is slowly moving away from water soluble solder pastes in favor of no-clean solder pastes. This shift in usage of solder paste is driven by an effort to eliminate the water wash process. Some components cannot tolerate water wash and elimination of water washing streamlines the SMT process. Despite this shift, certain applications lend themselves to the use of water soluble solder paste.

This paper details the research and development of a new water soluble lead-free solder paste which improves on the performance characteristics of existing technologies.
