Description
EO-Y-005A is universally suitable for the wave- and selective soldering of printed circuit boards and contains organic, halogen-free, activating additives formulated with a small amount of synthetic resin. This flux was developed in a combination with leaded and lead-free solders, coordinated especially to the thermal requirements of the soldering process. EO-Y-005A contains special alcoholic additives for the stabilization and improvement of the drying time in comparison with conventional water- or partially water-based fluxes.
Recommendations for the processing of this flux:
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 favors the soldering operation.
Foam fluxes: Not recommended
Spray fluxing: 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 behavior (optically very clean, high SIR)
