ECOFREC 303E
Low-residue, VOC-free soldering flux
- Water-based no-clean liquid flux
- Wave & selective soldering
- Excellent wetting & High electronic reliability
ECOFREC 303E
Is a low-residue, no-clean, VOC-free flux designed for wave and selective soldering. It is based on our legacy product ECOFREC 303, offering enhanced wetting performance while maintaining exceptionally low residue levels.
Thanks to its high SIR values, cleaning before applying compatible conformal coatings is generally unnecessary.
