It was widely believed that the move to lead-free soldering would create more environmentally-friendly conditions however because of the higher temperatures required and extra flux used lead-free soldering smoke emissions actually contain more fine dust particles which are easier to breathe in. Soldering and rework, like other activities involving adhesives, welding and laser applications, create particles and gases which can be harmful to workers. Why soldering fumes are a risk to workers In this article we look at the nature of the risk, the relevant legislation, and how fume extraction can be managed safely, effectively, energy-efficiently and in compliance with regulatory demands. Even in regions without such legislation employers have an ethical duty to provide such protection. Most countries recognise this and enforce legislation to ensure that employers protect their employees from these harmful effects. Employers may face expensive compensation claims as a result. Further hand soldering and desoldering is frequently used in rework stations to carry out repairs and upgrades.Īll of this soldering activity generates fumes which can cause long term, serious harm to operators if inhaled. A small part of the operation is automated, using wave soldering machines, with the majority being manual as operators add individual components using hand soldering irons. Essential considerations for managing soldering fume extractionĮlectronics production is heavily concerned with soldering components on to printed circuit boards (PCBs).
