Ecofrec™ TF49

  • No clean tacky flux
  • Flip Chip, spheres soldering & components rework
  • Transparent colorless residue & high viscosity

A halogen free, no-clean tacky flux designed for lead-free and leaded applications. After reflow, the residue is non-corrosive.  Best in class for dispensing, dipping and printing applications. Best choice for applications where the residues cosmetics are important.






  • High viscosity tacky flux to keep components firm in place
  • Non corrosive and transparent colorless residues


  • Stable process as great reproducible volumes of flux are applied
  • no flux residues cleaning required


  • No CMR substances
  • Free of halide (Fluoride, Chloride, Bromide) and amine
  • RoHS & REACH compliant
