Abstract

A fluxer applies powdered flux to an object. The fluxer includes an enclosure that defines a chamber where the object is fluxed. The enclosure includes an inlet for receiving the object into the chamber prior to application of the flux and an outlet for discharging the object from the chamber after the flux has been applied. A conveyor extends through the enclosure for traversing the object into and out of the chamber. The fluxer also includes a hopper for storing the flux and an applicator in fluid communication with the hopper for applying the flux to the object. A flux recovery system is in fluid communication with the chamber to introduce and maintain a negative pressure within the chamber. As a result, excess flux is retained within the enclosure. This excess flux can then be recovered and recycled to the hopper.
