Abstract Water soluble solder paste developed using T7 powder particles revealed good solderability when printed on copper, tin, gold flash nickel plated surfaces and on reflow as well. Its cross-section showed absence of voids, good wetting and soldering to the plated surfaces with angle of contact from 42° to 84° on reflow. All the solder interface are integral with pad/substrate surfaces and revealed formation of tin based intermetallics. T7 solder powder processed using Welco technology showed spherical, clean, smooth, un-agglomerated powder particles with the size range of 2 to 12μm. The developed solder paste is used for fine pitch applications.
