ABSTRACT:
Fluxing station (34) has a flux dispenser (52) where liquid flux cascades down steps (88, 90). Circulating pump (46) draws liquid flux from a reservoir (54) below the steps and recirculates it to cascade down the steps. There is provision to add makeup flux from reservoir (38) or supply a cleaning liquid such as alcohol from reservoir (37) to clean the circulating system. A drain (62) is provided. Electrical components can be positioned with their leads on the steps so that liquid flux cascades thereover for accurately fluxing only the ends of the leads. Two or more pairs of steps, with different spacing, may be provided to accommodate components of different lengths.
