EO-B-004 is a multiflux intended for wave (spray fluxes), selective, immersion, or manual soldering processes, it consists of alcohol-based solvents, synthetic resin and halogen-free activators. With a 1.8% 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 PCBA properly soldered with EO-B-004.

Customer added value:

  • Wide range of applications (multiflux)
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (very high thermal stability, good activity over a long interval)
  • Recommended for N2-systems
  • Very low solids content
  • High surface resistance of flux residues (SIR) (even with selective special testing)
