An apparatus for applying a soldering alloy to an element to be soldered including an open-channeled member having a receiving region for holding the element, a vacuum system connected to the member for creating a negative pressure through the open channel and at the receiving region sufficient to retain the element against the receiving region, a heating coil connected to the member for conducting heat to the element at a soldering temperature, and a gas distribution and heating system for providing heated gas to a soldering alloy at a temperature sufficient to melt and provide at least one soldering connection on the heated element. The invention also comprises a method for providing heat to an element to be soldered substantially by conduction and heat to a soldering alloy substantially by convection employing a heated gas all at temperatures sufficient to provide a soldered connection without damaging the element being soldered.
