Description

The invention relates to a foam fluxer, consisting of a container with a central area delimited by protruding wall parts, Foam pipes are arranged at the bottom, and with guides arranged above the container wall for circuit boards or the like.

The object of the innovation is to improve such known foam fluxers.

For this purpose, the innovation provides that the protruding wall parts only up to below the height of the container walls range and wear flaps around the upper edges of these wall parts in an erect and a folded end position can be pivoted.

In the upright end position, the flaps protrude the container wall up close to the guides, so that the foam above the liquid level in the Container also against the circuit boards or the like. Can rise. After swiveling the flaps, you can the foam flows off to the side and then only slightly deviates from the upper edges of the wall parts mentioned out.

The air supply to the foam pipes needs a. Such a construction is not suitable for fluxing every new one Plate to be switched on again, rather it is sufficient to open the flaps after the correct positioning of the To erect plates on the guideways.

A foam fluxer according to the invention comprises a container 1, the / a central area 4 as well as the outer area delimited by means of protruding wall parts and 3 Chambers 5 and 6 is divided. These outer chambers are connected to the central area in a communicating manner.

Foam pipes 7 are arranged in the middle area, above which the foam to above the upper edges the wall parts 2 and 3 rises and can flow from there into the lateral chambers 5 and 6.

At the upper edges of the towering wall parts 2 and flaps 7 and 8 are now hinged, which in an upper End position and can be pivoted into a lowered end position.

Above the container walls are lateral guides 9 for supporting plates to be beluxed or for a slidable one Arranged slide 1o on which the plates to be fluxed are placed.

Fig. 1 shows the position of the flaps when the slide is retracted. Here the flap 8 is in its erect state End position and the flap 7 shown in the folded end position so that the carriage over the middle area 4 of the container can be retracted.

Fig. 2 shows the working position in which the now erected flaps 7 and 8 form a chimney, in which the foam Ms can rise to the guides and above the container walls and so to fully wet the fluxing plates.

After a sufficient exposure time, the slide 1o is extended. This situation is shown in FIG. 3. Before extending the flap 8 is lowered,

while the flap 7 can remain erect. The foam can now go into the adjoining container space 6 flow off and now extends at most to the upper edge of the container walls.
