Abstract
A method and system for introducing flux onto at least one surface of a solder pump achieve their objects as follows. A solder pump nozzle is submerged into a flux reservoir. In response to such submersion, the flux in the reservoir is actively introduced into the solder pump nozzle. In one embodiment, the active introduction is achieved by creating a negative pressure in a solder pump nozzle such that flux fills a vacated volume. The created negative pressure is produced by moving a solder column, contained within the solder pump nozzle, under the influence of an applied electric current and an applied magnetic field.
