For the PCB electronics industry and many companies that use wave soldering and reflow soldering, the smoke and dust in the workshop must be removed, otherwise the company will be troubled by a series of problems such as production capacity, quality, environmental protection, and yield. PURE-AIR technology focuses on the development and manufacture of nederman portable welding fume extractor and reflow soldering fume extractor!

The wave soldering machine is selected to heat the welding area based on the basic principle of widespread heat transfer. The molten solder wave acts as a pyrogen. On the one hand, the fluidity is used to wash the foot pads, and on the other hand, it also has the effect of heat conduction. 

The foot pads are heated by this effect. In order to better ensure the temperature increase of the soldering area, the solder wave generally has a certain overall width, so that when the component is welded according to the wave, there will be sufficient time for heating and wetting. In the traditional wave soldering machine, a single wave is generally used, and the wave is relatively flat. With the application of lead solder, the double-wave method is mostly adopted at this stage.

The pin of the electronic device is solid, and the solder penetrates into the plated buried hole to give a stripe pattern. When the pin touches the solder wave, the liquid solder lifts up along the pin and the edge of the hole by virtue of the effect of interfacial tension. The development of capillary action of plated buried holes promotes the uplift of solder. After the solder reaches the solder layer of the PcB part, it spreads out under the effect of the interfacial tension of the solder layer. The rising solder discharges the flux vapor and gas in the buried hole, and then fills the buried hole. After cooling, spot welding is finally produced and the welding target is completed.

Dongguan PURE-AIR Technology, in the process of long-term cooperation with these wave soldering and reflow soldering companies, found that mobile welding fume extractor has effectively helped companies solve some key problems. So equipped with mobile welding fume extractor with filtration and reflow soldering fume extractor is the beginning of things these companies have to do.
