Abstract
Systems and methods for solder bonding that employ an equilibrium solidification process in which the solder is solidified by dissolving and alloying metals that raise the melting point temperature of the solder. Two or more structure surfaces may be solder bonded, for example, by employing heating to melt the solder and holding the couple at a temperature above the initial solder melting point of the solder until interdiffusion reduces the volume fraction of liquid so as to form a solid bond between surfaces before cooling to below the initial melting point of the solder.
