Recommendations for the processing of this flux:

This flux is very versatile in use, 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 heat-sensitive 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 lead as well as lead-free solder systems.
