ABSTRACT:
A mist of liquid coolant is introduced into the path of atomized, molten, solder droplets. The mist and other conditions within the chamber are engineered to enable the liquid coolant droplets in the mist to contract the surfaces of molten solder droplets and be flash vaporized upon contact, thereby rapidly extracting heat from the molten solder droplets and accelerating cooling and solidification to produce an enhanced solder ball as a product of this process.
