Electronics Industry Extraction
When solder flux is heated above 183 degrees Celsius (or higher for lead free) a complex mixture of resin acid particulates (smoke) and gases are generated - this is called ‘colophony’ and is produced from hand soldering, solder pots and fountains, wave solder machines and reflow ovens. It is important to understand how to keep dust away from electronics, electricians and machinery operators.
Fume extraction in the electronics industry is vital to avoid frequent inhalation of substances such as solder fumes, vapours from potting/ dipping and conformal coating. A typical solder fume is a mix of very small particles (smoke) and gases which can be explained as around 95% particulates (the physical smoke plume), and around 5% gases and vapours which can contain a cocktail of acetones, methyl alcohol, formaldehyde, carbon dioxide, diterpene acid, carbon monoxide and isopropyl alcohol.
