Abstract
A flux filtration system (10) for removing rosin flux from a heat transfer liquid (14). The flux and heat transfer liquid (14) on an article (17) that has been condensation soldered is drained into a pan (13) located within a condensation soldering facility (11). The pan (13) diverts the liquid-flux mixture from a boiling reservoir of the liquid (14) in the lower portion of the facility (11). The liquid-flux mixture drained during a plurality of batch soldering operations is accumulated in a coarse flux filter (21). Periodically the filter (21) outpulses the coarsely filtered material sequentially through a heat exchanger (23), a fine flux filter (24), a preheater (28) and is then returned to the reservoir in the facility (11). When the liquid-flux mixture is not being outpulsed from the filter (21), the liquid (14) from the reservoir flows into the heat exchanger (23) and passes through the remainder of the filtration system (10) to maintain a flow therethrough to clean the system and prevent buildup of flux within the system (10).
