EO-Y-014A is universally suitable for wave and selective soldering of PCBs. It contains organic, halogen-free, rosin-free, activating additives in a combination specially tuned to the thermal requirements of the wave soldering process with leaded and lead-free solders. EO-Y-014A contains small amounts of special alcoholic additives for stabilization and improved drying times compared to conventional water-based fluxes.
The solids content is 2.0 wt.-%.

Instructions for use:
This flux must be applied by spraying. After application, it is advisable to dry the flux in order to transform the liquid into fusible phase which favours the soldering operation.
Foamfluxing: Not recommended
Sprayfluxing: If possible, try at first a quantity of 20 – 30 ml/min. and observe the distribution of the flux. After that, correct to the quantity. Air-pressure: 18 – 22 l/min.
Preheating: For “simple” PCBs a preheating temperature of 80 – 110 °C is recommended, for “more complex” PCBs of 100 – 130 °C on the top side of the PCB. The use can be made both in leaded and lead-free solder systems.

Customer added value

  • Wide range of applications (multiflux)
  • 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)
