Description

Condensation recovery unit Technical Field The application relates to the technical field of reflow soldering auxiliary equipment, in particular to a condensation recovery device. Background The nitrogen reflow soldering is a common soldering method, namely soldering is performed under the protection of nitrogen, and is generally performed by adopting a nitrogen atmosphere furnace or a hot air circulation furnace under the nitrogen atmosphere, and solder between soldering parts is melted by placing the soldering parts under the nitrogen atmosphere and heating and maintaining a certain temperature and air pressure, so as to form soldering spots. In welding, in order to improve the utilization rate of nitrogen, the nitrogen is generally enabled to flow in a furnace for recycling, and because the nitrogen is contacted with the soldering flux when being used as a protective atmosphere for reflow welding, the possibility of doping the soldering flux in the circularly flowing nitrogen is easily caused, and when the nitrogen is circulated to a weldment, the doped soldering flux is contacted with the weldment and causes the possibility of pollution to the weldment, so that the welding quality is adversely affected.
