EO-Y-005C is universally suitable for wave and selective-soldering of PCBs. It contains organic, halogen-free, activating additives as well as synthetic resin in a combination specially tuned to the thermal requirements of the wave-soldering process with leaded and lead-free solders.
EO-Y-005C contains small amounts of special alcoholic additives for stabilization and improved drying time compared to conventional water-based fluxes.

This flux must be applied by spraying.
After application, it is advisable to dry the flux in order to transform the liquid into the fusible phase which favours the soldering operation.

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)
