    Abstract: A method for interconnecting multiple components of an electrical assembly with a solder joint, including the steps of positioning a first component adjacent to a second component to provide a connection area, dispensing a solid solder sphere to a capillary tube, wherein the capillary tube is positioned with an exit orifice above the connection area between the first and second components, applying a first laser through the capillary tube while measuring light from the first laser that reflects off the connection area as the solder sphere moves through the capillary tube, and applying a second laser to at least partially melt the solder sphere when the measured light decreases to a predetermined level and as the solder sphere falls from the exit orifice toward the connection area between the first and second components.
