Patent ID: 7131565

Claim:
A solder feeding device comprising: a reservoir being configured to melt a solid solder wire into molten solder, said reservoir being fluidly connectable to an injection molded solder system; a drive unit being configured to selectively feed said solid solder wire into said reservoir; a first lead in electrical communication with said drive unit; and a second lead in electrical communication with said drive unit, said first lead being positioned in said reservoir so that said first lead electrically communicates with said second lead through said molten solder when said molten solder reaches a triggering level and so that said first lead does not electrically communicate with said second lead when said level is below said triggering level, said drive unit being configured to feed said solid solder wire into said reservoir based upon a state of electrical communication between said first and second leads, wherein said reservoir is configured to maintain a positive pressure therein while said drive unit feeds said solid solder wire into said reservoir.
