    Abstract: A tool employing a solder foot (20) to deposit solder on a series of conductive surfaces (21, 22) as the tool moves. In one embodiment, non-wettable blade (18) attached to the tool breaks the film. A pair of sensors (15) coupled to a control circuit monitor the position of the solder foot and the position may be changed as a function of the operation to be performed, i.e. deposit, reflow, standby while tool is moved. In a second embodiment a discrete solder mass is extruded and deposited on a preheated pad. In a third embodiment, solder wire is delivered to an omnidirectional tool for deposition.
