  • Patent number: 5104689
    Abstract: The method and apparatus of the present invention permits the automated deposition of heated solder onto a plurality of conductive pads which are disposed in one or more linear arrays on a circuit board or other planar member. A robotically controlled arm is utilized to mount a solder nozzle and selectively manipulate the solder nozzle over the circuit board. The solder nozzle is first manipulated to a selected point offset in a known direction and distance from a first conductive pad by means of a data set which specifies the centroid and footprint for a selected group of conductive pads. After feeding solder into the solder nozzle, aligning the solder nozzle at a desired angle parallel to a linear array of conductive pads and lowering the solder nozzle until a solder droplet contacts the circuit board, the solder nozzle is manipulated at a substantially constant velocity toward the first conductive pad and thereafter along a selected line which tracks the linear array of conductive pads.
