The importance of soldering fume extraction

Depending on areas of application of the finished assembly and requirements of the components, various soldering alloys and flux agents are considered. During the soldering process, large parts of the flux agent and a small portion of the solder will evaporate. The emerging aerosols and particles could be released into ambient air. These airborne pollutants are far more than just an unfortunate side effect but can lead to serious medical conditions. Particularly dangerous substances are aldehydes, which emerge from materials containing colophony; some of them may be carcinogenic. In addition, gases are released from coatings, adhesives or substrates during heating of the assembly.

These gases also transport sticky aerosols, which build up in the soldering machines or – even worse – on the products and contaminate them. This leads to increased cleaning and maintenance costs, and the operability of the plant can be impaired. In addition, the manufactured products may even be corroded by the contaminations, which could affect functionality and quality.

In order to eliminate soldering fumes, it is not sufficient to provide for only good ventilation in the manufacturing environment. The use of efficient fume extraction technology is mandatory.

The variety of the available air purification systems is high. The selection of the appropriate unit depends on type and volume of pollution, the use in automated, semi-automated or manual production environments and on mobility as well as flexibility.

State of the art fume extraction units achieve such a high purificationg rate for the processing air that the cleaned air can even be re-circulated into the work area.
