Point-of-Source & Ambient Fume Purification for SMT and Electronics Assembly - LEFILTER Solution

Product Introduction:

LEFILTER offers a dual-pronged approach for electronics manufacturing cleanrooms. For point-of-source capture at soldering stations, wave soldering machines, or selective soldering heads, we provide high-efficiency benchtop or overhead fume extractors. These units feature multi-stage filtration: a pre-filter for larger particles, a primary HEPA-grade particulate filter (99.97% @ 0.3μm), and an integrated activated carbon filter layer to adsorb organic acid vapors from rosin-based fluxes. For broader ambient air purification in the assembly area, we supply ceiling-mounted or free-standing recirculation air cleaners. These units quietly draw in room air, pass it through similar HEPA and carbon stages, and return clean air, maintaining positive pressure and ISO class cleanliness without exhausting conditioned air.

Application Area:

This solution is critical for Surface Mount Technology (SMT) lines, PCB assembly, and rework stations where soldering and glue dispensing occur. The process releases ultra-fine particulate matter (<1.0 μm) and colophony (rosin) fumes. These contaminants can settle on sensitive electronic components, leading to corrosion, electrochemical migration, and premature device failure. Inhalation of these fumes by operators can cause respiratory irritation and occupational asthma. In precision electronics manufacturing, controlling airborne contamination is directly linked to product reliability, yield rates, and occupational health compliance.

Our Solution:

LEFILTER understands the balance between effective fume capture and maintaining a controlled cleanroom environment. Our engineers recommend a hybrid strategy: using low-volume, high-capture-efficiency extraction arms directly at the soldering iron tip or machine exhaust port to remove over 90% of pollutants at the source. This is complemented by ambient air scrubbers to manage any fugitive fumes and maintain overall air quality. Our equipment is designed for quiet operation (low dBA) and features filter change indicators for easy maintenance. By preventing fume spread, we help you protect valuable product, reduce rework and failure rates, and provide a safer, more comfortable environment for skilled technicians, all while preserving your costly HVAC energy.
