Extraction and filtration technology for soldering fumes and vapors Air pollution control in industrial and craft soldering processes

Soldering processes and applications Soldering processes are utilized in a wide range of industrial and craft sectors. It is an important and versatile technology for joining primarily metallic parts together, thus enabling the manufacture of various products. SOLDERING PROCESSES ARE UTILIZED IN: • Electronics manufacturing • Machinery and metalworking • Aviation and aerospace • Construction industry • Jewelry making • Instrument making • Arts and crafts • and more CURRENTLY APPLIED SOLDER PROCESSES: • Dip soldering • Piston soldering •W ave soldering • Reflow soldering • Selective...

Technologies and emissions Soldering processes are also subdivided according to the liquidus temperature of the solder and are used in different areas: SOFT SOLDERING HARD SOLDERING HIGH TEMPERATURE SOLDERING Liquidus temperature •C opper and copper alloys • Sheet steel • Aluminum • Zinc • Stainless steel • Steel • Brass • Copper • Silver (alloys) • Gold (alloys) • Stainless steel • Nickel • Cobalt • Ceramics Application examples • Electronics manufacturing • Electrical installation • Sanitary engineering •J ewelry and handicrafts • Heating construction • Instrument making • Plumbing...

Health risks and legal basis In many countries there are a number of legal regulations that prescribe how airborne pollutants in the process air must be removed. A distinction is made as to whether the substances are harmful to the brain, nerves or respiratory tract, or whether they are inhalable or alveolar. Material processing releases pollutants 100 μm COARSE DUST 10 μm FINE DUST 1 μm 0.1 μm FINEST DUST AND SMOKE The exact composition of the soldering fume depends on various factors, e.g. the solder used, flux, soldering temperature, and soldered materials. Therefore, an analysis of the...

Pollutant collection The filtration process begins with the capture Air pollutants are collected before filtration, because only what is captured can be filtered. The degree of capture forms the basis for the subsequent optimal filtration. Consequently, this results in the efficiency of the entire system and therefore the pollutant residues in the recirculated exhaust air. The greatest proximity to the pollutant source is crucial here. The selection of the best-suited collection element is also of great importance. ULT is at the customer's side to provide advice. Further information on the...
