Abstract

A solder alloy for use in automated soldering of workpieces by application thereto of liquid solder from a molten reservoir. The alloy consists essentially of from about 50 to 57.5% by weight tin, from about 1.5 to 4% by weight antimony, with the balance being substantially lead. The alloy is preferably further characterized in displaying a solidus-to-liquidus temperature range no greater than that of a 60/40 weight ratio tin/lead solder.
