The RS-4004 has been developed for use with wave and selective soldering. In addition, it can be used for manual and dip soldering a. The application can be done by means of all the conventional application methods. The solids content amounts to 3.5%. The soldering flux contains a corrosion inhibitor.
Application (recommended):
Multiflux: Wave soldering (spray fluxing), selective soldering, manual- and repair soldering, dip soldering

Customer added value:

  • Very wide range of applications (multiflux)
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (very high thermal stability, very high activity over a long interval)
  • Good residue behaviour (very clean, high SIR)
  • Successful passing of internal test (SIR selective)
