This flux is very versatile in use and OSP-compatible. Good results have been achieved with manual-, wave- and selective soldering. The general rule, to apply as little flux as possible, is also applicable for this product.

Spray fluxing: With the dosing option quantify the flux, first set to 30 – 40 ml/min., observe the even distribution of flux on the circuit board (if necessary test with heatsensitive paper) and then adjust to the optimal quantity.

Preheating: With “simple” circuit boards a preheating temperature of 80 – 110 °C is recommended on the top side of the circuit board, with “more complex” boards a temperature of 100 – 130 °C. It can be used both in solder systems containing leaded as well as lead-free solder systems.

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 behavior (very clean, high SIR)
  • Successful passing of internal test (SIR selective)
