EO-Y-014C 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 lead and lead-free solders. EO-Y-014C contains small amounts of special alcoholic additives for stabilization and improved drying times compared to conventional water-based fluxes.

The solids content is 4%.

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.

Instructions for use:

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..
