Air Quality sensor for smt area

What I would look at is the chemicals being used in the facility where the complaints are. Flux/flux gel, IPA, cleaning agents, etc. Perhaps you should limit the usage to certain people only, who would be trained how to properly use these. Something else - use extractors for workbenches, especially for the people doing rework. Fumes can be damaging long term, and people need to understand the risks if they don't use extraction. Use extraction for ovens too, if there is already, check for leaks in the ducting, check for any valves that have been accidentally closed (true story, happened). Clean/change the filters of the extractors as per manufacturer recommendation for all extraction units. If you have stencil/PCB washing machine in the production area, use an extractor there too - and/or switch to a less smelly cleaning agent. We use extractors everywhere, people understand the risks of not using them. Nobody ever complained about anything, unless somebody is burning a massive connector at the BGA rework station :D Regards, Tom

Good ventilation is also important to removing aerosols and other vapors. Make sure your building HVAC is pulling in a good portion of outside air. If people are complaining try to up the ratio of recirculated/outside air. This will add cost depending on your climate.

Air purifiers are another great solution but also have added cost of replacing the filters.

Fans to circulate air will help also
