Like all multi-fluxes, the EO-B-007A can be used for wave (spray fluxes) as well as for selective, manual, and dip soldering. The A version has a low 1.9% solids content. This variant was developed especially for full-tunnel nitrogen applications. It features a wide processing window and great temperature stability to guarantee a better soldering result than that obtained with traditional adipic acid solutions under full nitrogen. Soldering results and cleanliness are very good.

Practice has shown, that no washing is needed for PCBs properly soldered with EO-B-007A.

Customer added value:

  • Wide range of applications (multiflux)
  • Very good soldering properties (capillarity, wetting)
  • Available as concentrate (granulate)
  • Broad process window (very high thermal stability, good activity over a long interval)
  • Very good residue behaviour (very clean, high SIR)
  • Successful passing of internal test (SIR selective)
  • Recommended for N2-systems
  • Very low solids content
