The PM-334 soldering flux can be used for a wide range of applications. It fulfils all the requirements for use with wave, selective and manual soldering as well as dip tinning. In practice it is used mainly in manual and repair soldering and stranded wire tinning. In addition to canister products, soldering flux pens and dosing bottles are also available.

Customer added value

  • Very wide range of applications (multiflux)
  • Very good soldering properties (capillarity, wetting)
  • 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)
