• Solvent based no-clean liquid flux
  • Wave & selective soldering
  • High reliability and no visual residues

Developed to have a good wettability on different PCB lead free finish as OSP, Ni/Au, Sn, Ag. ECOFREC™ 202 is a very low dry extract flux which can be used for lead free soldering, by foam or by spray. Its activation system, without any halide (Fluoride, Chloride or Bromide) and no amine, is eliminated after wave soldering, without leaving any visible residue on printed circuit boards.




  • Compatible with a wide range of solder mask
  • Compatible with different PCB lead-free finishing as Ni/Au, Sn, Ag, HAL and OSP
  • good wetting
  • no visual flux residue after soldering
  • High SIR values and BONO test compatible
  • Possible to use with leaded and lead-free product


  • Passes Bono test to guarantee a long life time of your product.
  • No flux residue cleaning required
  • No interference with electrical test probes


  • No CMR substances
  • Free of halogen and amine
