Abstract
A filter (21) for removing flux from a hot heat transfer liquid-flux mixture. The heat transfers liquid-flux mixture is directed into a chamber (41) having a plurality of spaced, hollow members (64--64) through which a coolant passes. Upon being cooled the flux deposits on the surface of the members (64--64). The liquid, with substantial portions of the flux removed therefrom, then leaves the filter (21).
Claims3
A method of removing solder flux from a liquid-flux mixture, the method comprising the steps of:
- directing the liquid-flux mixture into a chamber having a plurality of spaced, substantially planar, hollow members arranged in a plurality of staggered, parallel rows within the chamber, said mixture being directed into said chamber in a direction normal to the planar, hollow members;
- passing a coolant through the hollow members to lower the temperature of the mixture to increase the viscosity of the flux to cause said flux to deposit on said planar hollow members;
- accumulating a predetermined amount of the directed liquid-flux mixture within the chamber;
- and
- discharging the liquid from the chamber after a predetermined period of time.

An apparatus for removing solder flux from a liquid-flux mixture, the apparatus comprising:
- a chamber adapted to accumulate the liquid-flux mixture;
- a plurality of spaced, substantially planar, hollow, members arranged in a plurality of staggered, parallel rows mounted within the chamber, through which a coolant flows to lower the temperature of the mixture to increase the viscosity of the flux to cause said flux to deposit on said planar hollow members;
- an input located in the chamber, above the substantially planar hollow members, through which the liquid-flux mixture is directed into the chamber in a direction normal to the planar hollow members;
- and
- an output located in the chamber below the substantially planar hollow members, through which the liquid is discharged from the chamber after a predetermined period of time.
