Claim:
An underfill material dispenser, comprising: a heater having a first end and an opposing second end, the heater further having an exterior surface and an interior surface; a plurality of heating ducts defined within the heater between the heater exterior surface and the heater interior surface, and extending from the heater first end to the heat second end; an underfill material chamber defined within the heater; a needle disposed within the underfill material chamber; a nozzle attached to the heater second end, wherein the nozzle includes an exit conduit; and a satellite trap attached to the nozzle, wherein the satellite trap comprises: a substantially cylindrical outer wall attached by a first end to the nozzle and having a second end opposing the satellite trap outer wall first end; a substantially cylindrical inner wall positioned substantially concentrically within the satellite trap outer wall and attached by a first end to the nozzle, wherein the satellite trap inner wall further includes a second end substantially opposing the satellite trap inner wall first end; a flange extending substantially perpendicularly from the satellite trap outer wall second end toward a centerline of the satellite trap; a flange lip extending substantially perpendicularly toward the nozzle from a portion of the flange nearest the satellite trap centerline, wherein the satellite trap outer wall, the flange, and the flange lip form a trap channel; and at least one air inlet conduit extending through the nozzle and angled to form two symmetrical air cones, within a passage defined by the satellite trap inner wall, upon introduction of air through the at least one air conduit.
