The EO-Y-003 has been developed to be used with wave and selective soldering.
Practice has shown that with the correct application, no washing of assembled printed circuit boards soldered with this flux is needed.

Customer added value

  • Wide range of applications
  • 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)
