Abstract

The invention relates to the field of soldering, namely, devices for tinning and soldering radio components and microcircuits. The aim of the invention is to improve the quality of tinning and brazing. To solve this problem, the mechanism for removing solder oxides is made in the form of a balanced T-shaped round arm 16, rigidly mounted on the swing axis, with a scraper 19 fixed on the upper 30 B 20 of the people's upper arm with the possibility of supporting it in an upturned position on the upper plane B of the bath 2 and adjacent to In the plane of the inclined tray 4 for resetting oxides. On the other arm of the lever 16, the counterweights 21 are mounted with the possibility of supporting in another tilted position on the limiting stop. Bath 2 is kinematically connected with the mechanism of its rise through the sliding articulated parallelogram. On the path of moving the base link 8 of the latter to the lower position, there is a stop 17 fixed on the axis 15 of the swing of the lever 16. This allows cleaning the surface of the solder from oxides and removing the latter from the bath before each immersion cycle of the parts. 4 il.

The invention relates to a device for lifting and lowering a bath for you to tin and solder a variety of components, -, and 2. For feeding the bath 2 with solder of preradio components and microcircuits by immersion in a molten beer.

The purpose of the invention is iioBbimeftHe of the quality of tinning and soldering,

Fig, 1 shows the device, a general view, with the upper position of the bath; in figure 2. - the same, with the lower position of the bath; FIG. 3 is a view along arrow A in FIG. 1; Fig, 4 shows the device from above.

In the housing 1 is placed bath 2 with integrated heating element 3.

In the upper part of the bath 2 finishes- 5 not 11 the adjusting screw is installed

30, which serves to precisely position the 2n upper position and change the depth of the radio components 29 in the molten solder 5.

The device works as follows.
