Durafuse™ LT is a novel solder paste mixed-alloy system for low-temperature reflow processes which require high drop shock reliability. Durafuse™ LT is made up of a low-melting In-containing alloy and higher-melting SAC alloy. The SnInAg alloy initiates joint fusion while the SAC alloy provides enhanced strength and
durability. Durafuse™ LT is ideal for high-reliability applications, which utilize thermally sensitive components.
