Like all multi-fluxes, the EO-B-002B can be used for wave (spray fluxes) as well as for selective, manual, and dip soldering. The B variant is the standard version with a 3% solids content. It is an all-round version. Soldering results and cleanliness are very good.  Even on pure copper surfaces good results are achieved– for instance when processing LEDs on heat sinks. Practice has shown, that no washing is needed for PCBA properly soldered with EO-B-002B.

The B variant is also offered as a metering pen or metering bottle. It is thus ideal for manual and repair soldering.

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)
