EO-G-002 is a purely water-based soldering flux for wave and selective soldering. It is ecologically harmless and non-flammable. The EO-G-002 with its soldering-related properties is at least just as good as comparable alcohol-based soldering fluxes.

The soldering results and the cleanliness of the circuit boards after the soldering process are very good.

In practice it has been shown that with the correct application, the washing of printed circuit boards soldered with this flux can be largely dispensed with.

Application (recommended): Wave soldering (spray fluxing), selective soldering

Customer added value:

  • Non-flammable (no legal restrictions for transport, storage and handling)
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (high thermal stability, good activity over a long interval)
  • Very good residue behaviour (optically very clean, high SIR)
