A method and system for rapid heat-sink soldering, having a workpiece gripper, an intense heat source, and an optional air-jet cooling system, is provided for soldering workpieces to substrates of dissimilar material composition. The workpiece gripper selectively positions the workpiece closely adjacent the substrate and continually removes excess heat from the workpiece, both during and after the application of heat to the workpiece. Upon termination of the heat application, air-jet cooling can be provided to the workpiece to quickly cool the terminal and the molten layer of solderable material.
