Like all multi-fluxes, the EO-B-002B can be used both for wave (spray fluxes) as well as for selective, manual, and dip soldering. The B variant on the other hand represents the standard version with a 3% solids content. An all-round version is involved here. Soldering results and cleanliness are quite good. Good results are achieved even on a pure copper surface – 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)
